USN-6221-1: Linux kernel vulnerabilities It was discovered that a race condition existed in the overlay file system implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash). (CVE-2021-20321) It was discovered that the virtual terminal (vt) device implementation in the Linux kernel contained a race condition in its ioctl handling that led to an out-of-bounds read vulnerability. A local attacker could possibly use this to expose sensitive information. (CVE-2021-3753) It was discovered that the ext4 file system implementation in the Linux kernel contained a use-after-free vulnerability. An attacker could use this to construct a malicious ext4 file system image that, when mounted, could cause a denial of service (system crash). (CVE-2022-1184) Pawan Kumar Gupta, Alyssa Milburn, Amit Peled, Shani Rehana, Nir Shildan and Ariel Sabba discovered that some Intel processors with [ more… ]
Announcing Windows 11 Insider Preview Build 25905 Hello Windows Insiders, today we are releasing Windows 11 Insider Preview Build 25905 to the Canary Channel. We are releasing ISOs for this build – they can be downloaded here. Starting with today’s build, Windows Insiders in the Canary Channel will notice that the name of the branch shown in the desktop watermark has changed back to RS_PRERELEASE. As a result of this change, Insiders will notice that some features that were previously removed temporarily with the switch over to ZN_RELEASE have now returned – in addition to some new features mentioned below. REMINDER: As builds released to the Canary Channel are “hot off the presses,” we will offer limited documentation for builds flighted to the Canary Channel including documenting only the most significant and highly impactful known issues. Please note that we will [ more… ]
USN-6219-1: Ruby vulnerabilities It was discovered that Ruby incorrectly handled certain regular expressions. An attacker could possibly use this issue to cause a denial of service. This issue only affected Ubuntu 20.10 and Ubuntu 20.04 LTS. (CVE-2023-28755) It was discovered that Ruby incorrectly handled certain regular expressions. An attacker could possibly use this issue to cause a denial of service. This issue exists because of an incomplete fix for CVE-2023-28755. (CVE-2023-36617) Source: USN-6219-1: Ruby vulnerabilities
USN-6220-1: Linux kernel vulnerabilities Hangyu Hua discovered that the Flower classifier implementation in the Linux kernel contained an out-of-bounds write vulnerability. An attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-35788, LP: #2023577) It was discovered that for some Intel processors the INVLPG instruction implementation did not properly flush global TLB entries when PCIDs are enabled. An attacker could use this to expose sensitive information (kernel memory) or possibly cause undesired behaviors. (LP: #2023220) Source: USN-6220-1: Linux kernel vulnerabilities
