CVE-2016-6136

Condición de carrera en la función audit_log_single_execve_arg en kernel/auditsc.c en el kernel de Linux hasta la versión 4.7 permite a usuarios locales eludir restricciones de set de caracteres intencionados o interrumpir la auditoria del sistema de llamada cambiando una cierta cadena, también conocido como una vulnerabilidad de "doble recuperación".

When creating audit records for parameters to executed children processes, an attacker can convince the Linux kernel audit subsystem can create corrupt records which may allow an attacker to misrepresent or evade logging of executing commands.

The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix: When creating audit records for parameters to executed children processes, an attacker can convince the Linux kernel audit subsystem can create corrupt records which may allow an attacker to misrepresent or evade logging of executing commands. A flaw was found in the Linux kernel's implementation of the SCTP protocol. A remote attacker could trigger an out-of-bounds read with an offset of up to 64kB potentially causing the system to crash.
