Detailsinfo

A vulnerability was found in Linux Kernel 3.12 (Operating System) and classified as critical. This issue affects an unknown code block of the file wlags49_h2/wl_priv.c of the component Station Name Handler. The manipulation with an unknown input leads to a memory corruption vulnerability. Using CWE to declare the problem leads to CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Multiple buffer overflows in drivers/staging/wlags49_h2/wl_priv.c in the Linux kernel before 3.12 allow local users to cause a denial of service or possibly have unspecified other impact by leveraging the CAP_NET_ADMIN capability and providing a long station-name string, related to the (1) wvlan_uil_put_info and (2) wvlan_set_station_nickname functions.

The weakness was presented 10/30/2013 by Fabian Yamaguchi and Nico Golde as some unstracked linux kernel security fixes as confirmed mailinglist post (oss-sec). The advisory is shared at seclists.org. The public release was coordinated in cooperation with Linux. The identification of this vulnerability is CVE-2013-4514 since 06/12/2013. The exploitation is known to be difficult. An attack has to be approached locally. No form of authentication is needed for a successful exploitation. Technical details are known, but no exploit is available.

The vulnerability scanner Nessus provides a plugin with the ID 77074 (Mandriva Linux Security Advisory : kernel (MDVSA-2014:155)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Mandriva Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 195832 (Ubuntu Security Notification for Linux-lts-raring Vulnerabilities (USN-2069-1)).

Applying the patch staging: wlags49_h2: buffer overflow setting station name is able to eliminate this problem. The bugfix is ready for download at git.kernel.org. A possible mitigation has been published immediately after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at Tenable (77074), SecurityFocus (BID 63509†), OSVDB (99326†) and Vulnerability Center (SBV-42192†). seclists.org is providing further details.
