Detailsinfo

A vulnerability was found in Linux Kernel (Operating System). It has been classified as problematic. This affects some unknown processing of the file net/ipv6/udp.c. The manipulation of the argument udp_v6_get_port() with an unknown input leads to a infinite loop vulnerability. CWE is classifying the issue as CWE-835. The product contains an iteration or loop with an exit condition that cannot be reached, i.e., an infinite loop. This is going to have an impact on availability. The summary by CVE is:

The udp_v6_get_port function in udp.c in Linux 2.6 before 2.6.14-rc5, when running IPv6, allows local users to cause a denial of service (infinite loop and crash).

The issue has been introduced in 12/18/2003. The weakness was presented 10/21/2005 by Tetsuo Handa (Website). The advisory is shared at kernel.org. This vulnerability is uniquely identified as CVE-2005-2973 since 09/19/2005. Access to the local network is required for this attack to succeed. No form of authentication is needed for exploitation. Technical details and a public exploit are known.

The exploit is shared for download at exploit-db.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 673 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 21997 (CentOS 4 : kernel (CESA-2006:0493)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family CentOS Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 117771 (CentOS Security Update for Kernel (CESA-2006:0140)).

Upgrading eliminates this vulnerability. Applying a patch is able to eliminate this problem. The bugfix is ready for download at kernel.org. The best possible mitigation is suggested to be upgrading to the latest version. A possible mitigation has been published 5 months after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (23513), Exploit-DB (26382), Tenable (21997), SecurityFocus (BID 15156†) and OSVDB (20163†). See VDB-1879, VDB-1997, VDB-2134 and VDB-2178 for similar entries. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
