Red Hat Security Advisory

Synopsis:           Important: java-17-openjdk security and bug fix update  
Advisory ID:        RHSA-2024:0267-03  
Product:            Red Hat Enterprise Linux  
Advisory URL:       https://access.redhat.com/errata/RHSA-2024:0267  
Issue date:         2024-01-17  
Revision:           03  
CVE Names:          CVE-2024-20918  
====================================================================

Summary: 

An update for java-17-openjdk is now available for Red Hat Enterprise Linux 8, Red Hat Enterprise Linux 8.8 Extended Update Support, Red Hat Enterprise Linux 9, and Red Hat Enterprise Linux 9.2 Extended Update Support.

Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Description:

The java-17-openjdk packages provide the OpenJDK 17 Java Runtime Environment and the OpenJDK 17 Java Software Development Kit.

Security Fix(es):

* OpenJDK: array out-of-bounds access due to missing range check in C1 compiler (8314468) (CVE-2024-20918)

* OpenJDK: incorrect handling of ZIP files with duplicate entries (8276123) (CVE-2024-20932)

* OpenJDK: RSA padding issue and timing side-channel attack against TLS (8317547) (CVE-2024-20952)

* OpenJDK: JVM class file verifier flaw allows unverified bytecode execution (8314295) (CVE-2024-20919)

* OpenJDK: range check loop optimization issue (8314307) (CVE-2024-20921)

* OpenJDK: logging of digital signature private keys (8316976) (CVE-2024-20945)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Bug Fix(es):

* When Transparent Huge Pages (THP) are unconditionally enabled on a system, Java applications using many threads were found to have a large Resident Set Size (RSS). This was due to a race between the kernel transforming thread stack memory into huge pages and the Java Virtual Machine (JVM) shattering these pages into smaller ones when adding a guard page. This release resolves this issue by getting glibc to insert a guard page and prevent the creation of huge pages. (RHEL-13930, RHEL-13931, RHEL-13934, RHEL-13935)

Red Hat Security Advisory 2024-0246-03

Google has issued a security update for the Chrome browser that includes a patch for one zero-day vulnerability.

Google has released an update for Chrome which includes four security fixes, including one for a vulnerability that has reportedly already been exploited.

The easiest way to update Chrome is to allow it to update automatically, which basically uses the same method as outlined below but does not require your attention. But you can end up lagging behind if you never close the browser or if something goes wrong—such as an extension stopping you from updating the browser.

So, it doesn’t hurt to check now and then. And now would be a good time, given the severity of the vulnerability in this patch. My preferred method is to have Chrome open the page _chrome://settings/help_ which you can also find by clicking **Settings > About Chrome**.

If there is an update available, Chrome will notify you and start downloading it. Then all you have to do is relaunch the browser in order for the update to complete, and for you to be safe from those vulnerabilities.

After the update, the version should be 120.0.6099.224, or later

**Technical details**

Google never gives out a lot of information about vulnerabilities, for obvious reasons. Access to bug details and links may be kept restricted until a majority of users are updated with a fix. However, from the update page we can learn a few things.

Three vulnerabilities found by external researchers all lie in Chrome’s V8 JavaScript engine.

The Common Vulnerabilities and Exposures (CVE) database lists publicly disclosed computer security flaws. The three V8 vulnerabilities are listed as:

CVE-2024-0517: an out of bounds write in V8 in Google Chrome prior to 120.0.6099.224 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page.

An out-of-bounds write can occur when a program writes outside the bounds of an allocated area of memory, potentially leading to a crash or arbitrary code execution. This can happen when the size of the data written is larger than the size of the allocated memory area, when the data is written to an incorrect location within the memory area, or when the program incorrectly calculates the size or location of the data to be written.

CVE-2024-0518: a type confusion in V8 in Google Chrome prior to 120.0.6099.224 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page.

Type confusion vulnerabilities are programming flaws that happen when a piece of code doesn’t verify the type of object that is passed to it before using it. Type confusion can allow an attacker to feed function pointers or data into the wrong piece of code. In this case, it can lead to heap corruption.

Heap corruption occurs when a program modifies the contents of a memory location outside of the memory allocated to the program. The heap is an area of memory made available for use by the program. The program can request blocks of memory for its use within the heap.

CVE-2024-0519: out of bounds memory access in V8 in Google Chrome prior to 120.0.6099.224 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page.

An out-of-bounds memory access means that the software has access to data past the end, or before the beginning, of the intended buffer.

Google notes that it is aware of reports that an exploit for CVE-2024-0519 exists in the wild.

V8 is an open-source JavaScript and WebAssembly engine developed by the Chromium Project for Chromium and Google Chrome web browsers, so users of other Chromium based browsers, like Microsoft Edge, can expect to see similar updates in the near future.

Microsoft says it’s actively working on releasing a security patch and added:

> “It’s worth highlighting that Microsoft Edge’s enhanced security mode feature mitigates this vulnerability. You can opt-in into this security feature and have peace of mind that Microsoft Edge is protecting you against this exploit.”

Use the following steps to configure enhanced security in Edge.

1.  In Microsoft Edge, go to **Settings and more** > **Settings** > **Privacy, search, and services**.
2.  Under **Security**, verify that **Enhance your security on the web** is enabled.
3.  Select the option that’s best for your browsing.

The following toggle settings are available:

*   Toggle Off (Default): Feature is turned off
*   Toggle On – Balanced (Recommended): Microsoft Edge will apply added security protections when users visit unfamiliar sites but bypass those protections for commonly visited sites. This combination provides a practical level of protection against attackers while preserving the user experience for a user’s usual tasks on the web.
*   Toggle On – Strict: Microsoft Edge will apply added security protections for all the sites a user visits. Users may report some challenges accomplishing their usual tasks.

 Update Chrome! Google patches actively exploited zero-day vulnerability 

There are also multiple vulnerabilities in AVideo, an open-source video broadcasting suite, that could lead to arbitrary code execution.

Wednesday, January 17, 2024 12:00

Cisco Talos’ Vulnerability Research team has disclosed dozens of vulnerabilities over the past month, including more than 30 advisories in GTKWave and a critical vulnerability in ManageEngine OpManager. 

Cisco ASIG also recently discovered an information disclosure vulnerability in DuoUniversalKeycloakAuthenticator, an authentication solution for Keycloak, an open-source identity and access management solution.  

There are also multiple vulnerabilities in AVideo, an open-source video broadcasting suite, that could lead to arbitrary code execution. 

All the vulnerabilities mentioned in this blog post have been patched by their respective vendors, all in adherence to Cisco’s third-party vulnerability disclosure policy. 

For Snort coverage that can detect the exploitation of these vulnerabilities, download the latest rule sets from Snort.org, and our latest Vulnerability Advisories are always posted on Talos Intelligence’s website.  

**ManageEngine OpManager directory traversal vulnerability **

_Discovered by Marcin “Icewall” Noga._ 

A directory traversal vulnerability exists in the uploadMib functionality of ManageEngine OpManager, a network management solution. 

TALOS-2023-1851 (CVE-2023-47211) can be exploited if an adversary sends a target a specially crafted HTTP request, which could allow them to create a file in any location outside of the default MiBs file’s location directory. This vulnerability has a critical severity score of 9.1 out of 10. 

This vulnerability arises if the adversary uses OpManager and navigates to Settings -> Tools -> MiB Browser and selects “Upload MiB.” The arbitrary file they could eventually create can only be one of a few file extensions, however, including .txt, .mib and .mi2. 

**Multiple vulnerabilities in GTKWave **

_Discovered by Claudio Bozzato._ 

Cisco Talos recently discovered multiple vulnerabilities in the GTKwave simulation tool, some of which could allow an attacker to execute arbitrary code on the targeted machine. 

GTKwave is a wave viewer used to run different FPGA simulations. It includes multiple versions to run on macOS, Linux, Unix and Microsoft machines. The open-source software analyzes trace files to look at the results of simulations run across different design implementations, or to analyze protocols captured with logic analyzers.  

Talos researchers found a wide array of security issues across this software that affect different functions in GTKwave, many of which are triggered if an attacker can trick the targeted user into opening a specially crafted malicious file. In all, Talos recently released 33 advisories that cover more than 80 CVEs. Many of these issues are caused by the reuse of vulnerable code across the software. Other vulnerabilities are often duplicated by the adversary sending different file types as the initial infection document. 

There are eight integer overflow vulnerabilities that could result in memory corruption, and eventually, arbitrary code execution: TALOS-2023-1812 (CVE-2023-38618, CVE-2023-38621, CVE-2023-38620, CVE-2023-38619, CVE-2023-38623, CVE-2023-38622), TALOS-2023-1816 (CVE-2023-35004), TALOS-2023-1822 (CVE-2023-35989), TALOS-2023-1798 (CVE-2023-36915, CVE-2023-36916), TALOS-2023-1777 (CVE-2023-32650), TALOS-2023-1824 (CVE-2023-39413, CVE-2023-39414), TALOS-2023-1790 (CVE-2023-35992) and TALOS-2023-1792 (CVE-2023-35128). 

The most common vulnerability type Talos researchers found in GTKWave were out-of-bounds write issues that could lead to arbitrary code execution. All the following vulnerabilities could be exploited if a target opened an attacker-created file: 

*   TALOS-2023-1804 (CVE-2023-37416, CVE-2023-37419, CVE-2023-37420, CVE-2023-37418, CVE-2023-37417) 
*   TALOS-2023-1805 (CVE-2023-37447, CVE-2023-37446, CVE-2023-37445, CVE-2023-37444, CVE-2023-37442, CVE-2023-37443) 
*   TALOS-2023-1810 (CVE-2023-37282) 
*   TALOS-2023-1811 (CVE-2023-36861) 
*   TALOS-2023-1813 (CVE-2023-38649, CVE-2023-38648) 
*   TALOS-2023-1817 (CVE-2023-39235, CVE-2023-39234) 
*   TALOS-2023-1819 (CVE-2023-34436) 
*   TALOS-2023-1823 (CVE-2023-38657) 
*   TALOS-2023-1826 (CVE-2023-39443, CVE-2023-39444) 

TALOS-2023-1807 (CVE-2023-37921, CVE-2023-37923, CVE-2023-37922) can also lead to remote code execution, but in this case, is caused by an arbitrary write issue. 

For a complete list of all the vulnerabilities Talos discovered in GTKWave, refer to our Vulnerability Reports page here. 

**DuoUniversalKeycloakAuthenticator for Keycloak **

_Discovered by Benjamin Taylor of Cisco ASIG._ 

An information disclosure vulnerability exists in the instipod DuoUniversalKeycloakAuthenticator for Keycloak. Keycloak is an open-source identity and access management solution, and DuoUniversalKeyAuthenticator allows Keycloak to push a Cisco Duo notification to the Duo app, asking the user to authenticate in.  

The Keycloak extension for Duo, after it detects that initial authentication has succeeded with Keycloak, redirects the user’s browser to the configured duosecurity.com endpoint, sending the username and password in question each time. 

TALOS-2023-1907 (CVE-2023-49594) indicates that this is unnecessary exposure of this data, potentially allowing an attacker to steal or view this information. 

**Multiple vulnerabilities in WWBN AVideo **

_Discovered by Claudio Bozzato._ 

WWBN AVideo contains multiple vulnerabilities that an attacker could exploit to carry out a range of malicious actions, including brute-forcing user credentials and forcing a targeted user to reset their password to something the attacker knows. 

AVideo is a web application, mostly written in PHP, that allows users to create audio and video sharing websites. Users can import videos from other sources, like YouTube, encode the videos and then make them shareable in various ways. 

There are multiple cross-site scripting vulnerabilities in AVideo that could allow an attacker to execute arbitrary JavaScript code on the targeted machine: 

*   TALOS-2023-1882 (CVE-2023-48730) 
*   TALOS-2023-1883 (CVE-2023-48728) 
*   TALOS-2023-1884 (CVE-2023-47861) 

An attacker could exploit these vulnerabilities by tricking a user into visiting a specially crafted web page. 

There are three other vulnerabilities — TALOS-2023-1869 (CVE-2023-47171), TALOS-2023-1881 (CVE-2023-49738) and TALOS-2023-1880 (CVE-2023-49864, CVE-2023-49863, CVE-2023-49862) — that could allow adversaries to read arbitrary files with an HTTP request targeting different parameters in AVideo’s “objects/aVideoEncoderReceiveImage.json.php” file. 

Talos researchers also discovered TALOS-2023-1896 (CVE-2023-49589), an insufficient entropy vulnerability that can allow an attacker to forge a password reset for an administrator account. This could allow an adversary to reset a user’s account, set a new password that only the adversary knows, and then log in with that account information. An adversary could also exploit TALOS-2023-1897 (CVE-2023-50172) to prevent AVideo from sending an email to the associated account’s email address alerting them of the password reset process, so exploitation becomes less evident. 

Similarly, TALOS-2023-1900 (CVE-2023-49599) can also be exploited using this method, but this vulnerability targets administrator accounts. 

The most serious vulnerability Talos discovered in AVideo is TALOS-2023-1886 (CVE-2023-47862), a local file inclusion vulnerability that could eventually lead to arbitrary code execution. This vulnerability has a severity score of 9.8 out of 10. TALOS-2023-1885 (CVE-2023-49715) is an unrestricted php file upload vulnerability that can also lead to code execution, but only when used in conjunction with a local file inclusion vulnerability like TALOS-2023-1886. 

TALOS-2023-1898 (CVE-2023-49810) could be exploited in AVideo by sending a specially crafted HTTP request. An adversary could exploit this vulnerability to bypass the CAPTCHA process when trying to log into the service, therefore making it easier for an attacker to attempt to brute force login credentials or password-guessing attacks.

Critical vulnerability in ManageEngine could lead to file creation, dozens of other vulnerabilities disclosed by Talos to start 2024
