Descriptions

Integer overflow in the vfprintf function in stdio-common/vfprintf.c in glibc 2.14 and other versions allows context-dependent attackers to bypass the FORTIFY_SOURCE protection mechanism, conduct format string attacks, and write to arbitrary memory via a large number of arguments.

Desbordamiento de enteros en la función vfprint en stdio-common/vfprint.c en glibc v2.14 y otras versiones que permite a isiarios dependientes del contexto eludir el mecanismo de protección FORTIFY_SOURCE, llevar a cabo ataques de cadena de formato y escribir de forma arbitraria en memoria a través de un gran número de argumentos.

Multiple vulnerabilities have been found in GNU C Library, the worst of which allowing arbitrary code execution and privilege escalation. Versions less than 2.15-r3 are affected.
