Detailsinfo

A vulnerability classified as problematic has been found in FreeBSD 8.4/9.3/10.1 (Operating System). Affected is an unknown function of the component SCTP. The manipulation with an unknown input leads to a null pointer dereference vulnerability. CWE is classifying the issue as CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. This is going to have an impact on availability. CVE summarizes:

The sctp module in FreeBSD 10.1 before p5, 10.0 before p17, 9.3 before p9, and 8.4 before p23 allows remote attackers to cause a denial of service (NULL pointer dereference and kernel panic) via a crafted RE_CONFIG chunk.

The weakness was disclosed 01/27/2015 as FreeBSD-SA-15:03.sctp as confirmed advisory (Website). The advisory is available at security.FreeBSD.org. This vulnerability is traded as CVE-2014-8613 since 11/04/2014. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. The technical details are unknown and an exploit is not available. The advisory points out:

The input validation of received SCTP RE_CONFIG chunks is insufficient, and can result in a NULL pointer deference later.

The vulnerability scanner Nessus provides a plugin with the ID 92885 (FreeBSD : FreeBSD -- SCTP stream reset vulnerability (0aad3ce5-600a-11e6-a6c3-14dae9d210b8)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family FreeBSD Local Security Checks.

Applying a patch is able to eliminate this problem.

The vulnerability is also documented in the databases at Tenable (92885), SecurityFocus (BID 72345†), SecurityTracker (ID 1031649†) and Vulnerability Center (SBV-48366†). The entry VDB-68921 is pretty similar. If you want to get best quality of vulnerability data, you may have to visit VulDB.
