Descriptions

Integer overflow in the __tzfile_read function in glibc before 2.15 allows context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted timezone (TZ) file, as demonstrated using vsftpd.

Desbordamiento de entero en la función __tzfile_read en glibc anterior a v2.15 que permite a atacantes dependientes del contexto causar una denegación de servicios (caída) y posiblemente ejecutar código arbitrario a través de un fichero timezone (TZ), como se demostró usando vsftpd.

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.
