Descriptions

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.

Desbordamiento de búfer en el metodo extend_buffers del comparador expresiónes regulares (posix / regexec.c) en glibc, posiblemente, v2.17 y anteriores, permite a atacantes dependientes de contexto provocar una denegación de servicio (corrupción de memoria y caída) mediante caracteres multibyte artesanales.

A flaw was found in the regular expression matching routines that process multibyte character input. If an application utilized the glibc regular expression matching mechanism, an attacker could provide specially-crafted input that, when processed, would cause the application to crash.
