Detailsinfo

A vulnerability, which was classified as critical, was found in Linux Kernel 2.6.23 (Operating System). Affected is the function sctp_process_init. The manipulation with an unknown input leads to a improper authentication vulnerability. CWE is classifying the issue as CWE-287. When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct. This is going to have an impact on availability. CVE summarizes:

sctp in Linux kernel before 2.6.25.18 allows remote attackers to cause a denial of service (OOPS) via an INIT-ACK that states the peer does not support AUTH, which causes the sctp_process_init function to clean up active transports and triggers the OOPS when the T1-Init timer expires.

The bug was discovered 09/19/2008. The weakness was shared 10/15/2008 (Website). The advisory is shared for download at redhat.com. This vulnerability is traded as CVE-2008-4576 since 10/15/2008.
