CVE-2012-4424

Publication date 9 October 2013

Last updated 24 July 2024

Ubuntu priority

Low

Why this priority?

Stack-based buffer overflow in string/strcoll_l.c in the GNU C Library (aka glibc or libc6) 2.17 and earlier allows context-dependent attackers to cause a denial of service (crash) or possibly execute arbitrary code via a long string that triggers a malloc failure and use of the alloca function.
