A vulnerability, which was classified as problematic, was found in Linux Kernel 3.10 (Operating System). Affected is an unknown code block in the library libceph of the component CEPH auth_reply Messages. The manipulation with an unknown input leads to a null pointer dereference vulnerability. CWE is classifying the issue as CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. This is going to have an impact on availability. CVE summarizes:

net/ceph/auth_none.c in the Linux kernel through 3.10 allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via an auth_reply message that triggers an attempted build_request operation.

The weakness was released 07/01/2013 by Prasad J Pandit as 54042 as not defined advisory (Secunia). The advisory is shared for download at secunia.com. This vulnerability is traded as CVE-2013-1059 since 01/11/2013. The exploitability is told to be difficult. It is possible to launch the attack remotely. The requirement for exploitation is a authentication. There are known technical details, but no exploit is available.
