Improper Input Validation vulnerability in Apache Tomcat. Incorrect error handling for some invalid HTTP priority headers resulted in incomplete clean-up of the failed request which created a memory leak. A large number of such requests could trigger an OutOfMemoryException resulting in a denial of service. This issue affects Apache Tomcat: from 9.0.76 through 9.0.102, from 10.1.10 through 10.1.39, from 11.0.0-M2 through 11.0.5. Users are recommended to upgrade to version 9.0.104, 10.1.40 or 11.0.6 which fix the issue.

### Summary There is a possibility for denial of service by memory exhaustion when `net-imap` reads server responses. At any time while the client is connected, a malicious server can send can send a "literal" byte count, which is automatically read by the client's receiver thread. The response reader immediately allocates memory for the number of bytes indicated by the server response. This should not be an issue when securely connecting to trusted IMAP servers that are well-behaved. It can affect insecure connections and buggy, untrusted, or compromised servers (for example, connecting to a user supplied hostname). ### Details The IMAP protocol allows "literal" strings to be sent in responses, prefixed with their size in curly braces (e.g. `{1234567890}\r\n`). When `Net::IMAP` receives a response containing a literal string, it calls `IO#read` with that size. When called with a size, `IO#read` immediately allocates memory to buffer the entire string before processing continu...

EXECUTIVE SUMMARY CVSS v3 10.0 ATTENTION: Exploitable remotely/low attack complexity Vendor: Schneider Electric Equipment: Modicon M580, Modicon M340, Modicon Premium, and Modicon Quantum Vulnerabilities: Trust Boundary Violation, Uncaught Exception, Exposure of Sensitive Information to an Unauthorized Actor, Authentication Bypass by Spoofing, Improper Access Control, Reliance on Untrusted Inputs in a Security Decision, Out-of-bounds Read 2. RISK EVALUATION Successful exploitation of these vulnerabilities may risk execution of unsolicited command on the PLC, which could result in a loss of availability of the controller. 3. TECHNICAL DETAILS 3.1 AFFECTED PRODUCTS Schneider Electric reports that the following products are affected: Modicon M580: All versions prior to 2.90 (CVE-2018-7846, CVE-2018-7849, CVE-2018-7848, CVE-2018-7842, CVE-2018-7847, CVE-2018-7850, CVE-2018-7853, CVE-2018-7854, CVE-2019-6808, CVE-2019-6828, CVE-2019-6829, CVE-2019-6809) Modicon Momentum CPU (pa...

Mattermost versions 10.4.x <= 10.4.2, 10.5.x <= 10.5.0, 9.11.x <= 9.11.10 fail to properly validate the props used by the RetrospectivePost custom post type in the Playbooks plugin, which allows an attacker to create a specially crafted post with maliciously crafted props and cause a denial of service (DoS) of the web app for all users.

Mattermost versions 10.4.x <= 10.4.2, 10.5.x <= 10.5.0, 9.11.x <= 9.11.10 fail to validate the uniqueness and quantity of task actions within the UpdateRunTaskActions GraphQL operation, which allows an attacker to create task items containing an excessive number of actions triggered by specific posts, overloading the server and leading to a denial-of-service (DoS) condition.

### Impact The local file storage implementation does not restrict the size of uploaded files. An attacker could exploit this by uploading excessively large files, potentially causing the server to run out of space and return HTTP 500 error, resulting in a denial of service. The severity of the vulnerability is mitigated by the fact that the application UI and the generic REST API are typically accessible only to authenticated users. ### Patches The problem has been fixed in CUBA 7.2.23. ### Workarounds A workaround for those who are unable to upgrade: [Disable Files Endpoint in CUBA Application](https://docs.jmix.io/jmix/files-vulnerabilities.html#disable-files-endpoint-in-cuba-application). ### References [Files Functionality Vulnerabilities :: Jmix Documentation](https://docs.jmix.io/jmix/files-vulnerabilities.html) Similar vulnerability in Jmix: [DoS in the Local File Storage · Advisory · jmix-framework/jmix](https://github.com/jmix-framework/jmix/security/advisories/GHSA-...

### Impact The local file storage implementation does not restrict the size of uploaded files.

The severity of the vulnerability is mitigated by the fact that the application UI and the generic REST API are typically accessible only to authenticated users. Additionally, the /files endpoint in Jmix requires specific permissions and is disabled by default. ### Patches The problem has been fixed in Jmix 1.6.2+ and 2.4.0+. ### Workarounds A workaround for those who are unable to upgrade: [Disable Files Endpoint in Jmix Application](https://docs.jmix.io/jmix/files-vulnerabilities.html#disable-files-endpoint-in-jmix-application).
