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.
dc5103364dcaf34b9733e914efeb23949628b3316a7502944e9a2800aca0bbdbUbuntu 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.
885d7737c8896c4979eff3130aedfac27d41d771214fabcaa738e3479072e0e6Qualys 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).
848273d3a06e2a275e111a84edea6cdd3e2e29de8b47a4efd45b2d0d9c53c768Qualys 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.
f022f88e03996ad79c15bbc5396c143469581fda50195569cb1d3981ecc6fad8Debian 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.
