CVE-2013-7271

https://notcve.org/view.php?id=CVE-2013-7271

The x25_recvmsg function in net/x25/af_x25.c in the Linux kernel before 3.12.4 updates a certain length value without ensuring that an associated data structure has been initialized, which allows local users to obtain sensitive information from kernel memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg system call. La función x25_recvmsg en net/x25/af_x25.c en el kernel Linux anteriores a 3.12.4 actualiza cierto valor de longitud sin asegurarse que una estructura de datos asociada fué inicializada, lo que permite a usuarios locales obtener información sensible de la memoria dle kernel a través de una llamada de sistema (1) recvfrom, (2) recvmmsg o (3) recvmsg • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=f3d3342602f8bcbf37d7c46641cb9bca7618eb1c http://secunia.com/advisories/55882 http://secunia.com/advisories/56036 http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.12.4 http://www.openwall.com/lists/oss-security/2013/12/31/7 http://www.securityfocus.com/bid/64746 http://www.ubuntu.com/usn/USN-2109-1 http://www.ubuntu.com/usn/USN-2110-1 http://www.ubuntu.com/usn/USN-2113- • CWE-20: Improper Input Validation •
