CVE-2013-0242

Publication date 8 February 2013

Last updated 24 July 2024

Ubuntu priority

Low

Why this priority?

Buffer overflow in the extend_buffers function in the regular expression matcher (posix/regexec.c) in glibc, possibly 2.17 and earlier, allows context-dependent attackers to cause a denial of service (memory corruption and crash) via crafted multibyte characters.
