UnknownEPSS 3.38%

Last modified

CVE-2012-4424 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 3.38% chance of exploitation in the next 30 days.
