Ubuntu Security Notice 6608-2 - It was discovered that the CIFS network file system implementation in the Linux kernel did not properly validate the server frame size in certain situation, leading to an out-of-bounds read vulnerability. An attacker could use this to construct a malicious CIFS image that, when operated on, could cause a denial of service or possibly expose sensitive information. Xingyuan Mo discovered that the netfilter subsystem in the Linux kernel did not properly handle inactive elements in its PIPAPO data structure, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.

Ubuntu Security Notice 6626-2 - Quentin Minster discovered that a race condition existed in the KSMBD implementation in the Linux kernel when handling sessions operations. A remote attacker could use this to cause a denial of service or possibly execute arbitrary code. Marek Marczykowski-Górecki discovered that the Xen event channel infrastructure implementation in the Linux kernel contained a race condition. An attacker in a guest VM could possibly use this to cause a denial of service.

Ubuntu Security Notice 6634-1 - Brennan Conroy discovered that .NET with SignalR did not properly handle malicious clients. An attacker could possibly use this issue to cause a denial of service. Bahaa Naamneh discovered that .NET with OpenSSL support did not properly parse X509 certificates. An attacker could possibly use this issue to cause a denial of service.

QR code attacks are particularly dangerous because they move the attack vector off a protected computer and onto the target’s personal mobile device, which usually has fewer security protections in place and ultimately has the sensitive information that attackers are after.

Red Hat Security Advisory 2024-0778-03 - An update for Jenkins and Jenkins-2-plugins is now available for OpenShift Developer Tools and Services for OCP 4.12. Issues addressed include bypass, code execution, cross site request forgery, cross site scripting, denial of service, improper authorization, information leakage, insecure permissions, and open redirection vulnerabilities.

Red Hat Security Advisory 2024-0774-03 - An update is now available for Red Hat Certificate System 10.4 for RHEL 8. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link in the References section. Issues addressed include a memory leak vulnerability.

### Problem Entities of the File Abstraction Layer (FAL) could be persisted directly via `DataHandler`. This allowed attackers to reference files in the fallback storage directly and retrieve their file names and contents. The fallback storage ("zero-storage") is used as a backward compatibility layer for files located outside properly configured file storages and within the public web root directory. Exploiting this vulnerability requires a valid backend user account. ### Solution Update to TYPO3 versions 8.7.57 ELTS, 9.5.46 ELTS, 10.4.43 ELTS, 11.5.35 LTS, 12.4.11 LTS, 13.0.1 that fix the problem described. #### ℹ️ Strong security defaults - Manual actions required When persisting entities of the File Abstraction Layer directly via DataHandler, `sys_file` entities are now denied by default, and `sys_file_reference` & `sys_file_metadata` entities are not permitted to reference files in the fallback storage anymore. When importing data from secure origins, this must be explicitly ...

A vulnerability in Roundcube webmail is being actively exploited and CISA is urging users to install an updated version.

P11-kit is an integral component to enable Hardware Security Module (HSM) and related technologies around PKCS#11. Over the years, its focus had mostly been on the library, with the bundled command-line tools not receiving much attention. When the user wanted to perform operations on the HSM or smartcard, they typically had to use tools from other packages. The most popular ones include p11tool from GnuTLS, modutil from NSS, and pkcs11-tool from OpenSC.With p11-kit 0.25.1 release, the p11-kit command-line tool bundled with p11-kit has been extended with a handful of utilities, to make it possi

### Summary When processing requests authorization was improperly and insufficiently checked, allowing attackers to access far more functionality than users intended, including to the administrative and moderator functionality of the Pixelfed server. This vulnerability affects every version of Pixelfed between `v0.10.4` and `v0.11.9`, inclusive. A proof of concept of this vulnerability exists. ### Details TBA. This advisory will be edited with more details on 2024/02/25, when admins have been given some time to update, as we think any amount of detail would make it very easy to come up with an exploit. ### Impact This vulnerability affects every local user of a Pixelfed server, and can potentially affect the servers' ability to federate. Some user interaction is required to setup the conditions to be able to exercise the vulnerability, but the attacker could conduct this attack time-delayed manner, where user interaction is not actively required.
