A vulnerability has been found in Linux Kernel up to 3.8.5 (Operating System) and classified as problematic. This vulnerability affects the function tg3_read_vpd of the file /drivers/net/ethernet/broadcom/tg3.c of the component VPD Firmware Parser. The manipulation with an unknown input leads to a memory corruption vulnerability. The CWE definition for the vulnerability is 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. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

Heap-based buffer overflow in the tg3_read_vpd function in drivers/net/ethernet/broadcom/tg3.c in the Linux kernel before 3.8.6 allows physically proximate attackers to cause a denial of service (system crash) or possibly execute arbitrary code via crafted firmware that specifies a long string in the Vital Product Data (VPD) data structure.

The weakness was released 03/07/2013 by Oded Horovitz with PrivateCore as not defined mailinglist post (oss-sec). The advisory is shared for download at seclists.org. This vulnerability was named CVE-2013-1929 since 02/19/2013. The exploitation appears to be easy. The attack needs to be approached locally. No form of authentication is required for a successful exploitation. There are known technical details, but no exploit is available.
