Detailsinfo

A vulnerability was found in Linux Kernel up to 2.6.19.0 (Operating System) and classified as problematic. Affected by this issue is the function get_fdb_entries. The manipulation with an unknown input leads to a integer coercion vulnerability. Using CWE to declare the problem leads to CWE-192. Integer coercion refers to a set of flaws pertaining to the type casting, extension, or truncation of primitive data types. Impacted is confidentiality, integrity, and availability. CVE summarizes:

Integer overflow in the get_fdb_entries function in net/bridge/br_ioctl.c in the Linux kernel before 2.6.18.4 allows local users to execute arbitrary code via a large maxnum value in an ioctl request.

The bug was discovered 11/29/2006. The weakness was shared 11/30/2006 by Eugene Teo (Website). The advisory is available at projects.info-pull.com. This vulnerability is handled as CVE-2006-5751 since 11/06/2006. Access to the local network is required for this attack. No form of authentication is required for exploitation. Technical details are known, but there is no available exploit.

It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 1 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 27293 (openSUSE 10 Security Update : kernel (kernel-2705)), which helps to determine the existence of the flaw in a target environment.
