glibc packages fix security vulnerabilities","description":"The vfprintf function in stdio-common/vfprintf.c in GNU C Library (aka glibc)\n2.5, 2.12, and probably other versions does not \"properly restrict the use of\"\nthe alloca function when allocating the SPECS array, which allows context-\ndependent attackers to bypass the FORTIFY_SOURCE format-string protection\nmechanism and cause a denial of service (crash) or possibly execute arbitrary\ncode via a crafted format string using positional parameters and a large\nnumber of format specifiers (CVE-2012-3406).\n\nThe nss_dns implementation of getnetbyname could run into an infinite loop\nif the DNS response contained a PTR record of an unexpected format\n(CVE-2014-9402).\n\nAlso glibc lock elision (new feature in glibc 2.18) has been disabled\nas it can break glibc at runtime on newer Intel hardware (due to hardware\nbug)\n","status":"published","published":"2015-01-08T12:24:22Z","modified":"2026-04-16T06:26:15.221038973Z","updated_at":"2026-11-02T15:49:39.488462Z"},{"id":"openSUSE-SU-2024:10154-1","title":"glibc-2.24-2.3
