Ubuntu Security Notice USN-6620-1
Ubuntu Security Notice 6620-1 - It was discovered that the GNU C Library incorrectly handled the syslog function call. A local attacker could use this issue to execute arbitrary code and possibly escalate privileges.

A local attacker could use this issue to execute arbitrarycode and possibly escalate privileges.Update instructions:The problem can be corrected by updating your system to the followingpackage versions:Ubuntu 23.10: libc6 2.38-1ubuntu6.1After a standard system update you need to reboot your computer to make allthe necessary changes.References: https://ubuntu.com/security/notices/USN-6620-1 CVE-2023-6246, CVE-2023-6779, CVE-2023-6780Package Information: https://launchpad.net/ubuntu/+source/glibc/2.38-1ubuntu6.1Related news
Hello everyone! In this episode, I will talk about the February updates of my open source projects, also about projects at my main job at Positive Technologies and interesting vulnerabilities. Alternative video link (for Russia): https://vk.com/video-149273431_456239140 Let’s start with my open source projects.

Gentoo Linux Security Advisory 202402-1 - Multiple vulnerabilities in glibc could result in Local Privilege Escalation. Versions greater than or equal to 2.38-r10 are affected.
Qualys discovered a heap-based buffer overflow in the GNU C Library's __vsyslog_internal() function, which is called by both syslog() and vsyslog(). This vulnerability was introduced in glibc 2.37 (in August 2022).

Qualys discovered a memory corruption in the glibc's qsort() function, due to a missing bounds check. To be vulnerable, a program must call qsort() with a nontransitive comparison function (a function cmp(int a, int b) that returns (a - b), for example) and with a large number of attacker-controlled elements (to cause a malloc() failure inside qsort()). They have not tried to find such a vulnerable program in the real world. All glibc versions from at least September 1992 (glibc 1.04) to the current release (glibc 2.38) are affected, but the glibc's developers have independently discovered and patched this memory corruption in the master branch (commit b9390ba, "stdlib: Fix array bounds protection in insertion sort phase of qsort") during a recent refactoring of qsort().
Debian Linux Security Advisory 5611-1 - The Qualys Research Labs discovered several vulnerabilities in the GNU C Library's __vsyslog_internal() function (called by syslog() and vsyslog()). A heap-based buffer overflow (CVE-2023-6246), an off-by-one heap overflow (CVE-2023-6779) and an integer overflow (CVE-2023-6780) can be exploited for privilege escalation or denial of service.

Malicious local attackers can obtain full root access on Linux machines by taking advantage of a newly disclosed security flaw in the GNU C library (aka glibc). Tracked as CVE-2023-6246, the heap-based buffer overflow vulnerability is rooted in glibc's __vsyslog_internal() function, which is used by syslog() and vsyslog() for system logging purposes. It's said to have been accidentally
