The manipulation with an unknown input leads to a race condition vulnerability. The CWE definition for the vulnerability is CWE-362. The product contains a code sequence that can run concurrently with other code, and the code sequence requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence that is operating concurrently. As an impact it is known to affect availability. The summary by CVE is:

Race condition in fileserver in OpenAFS 1.3.50 through 1.4.5 and 1.5.0 through 1.5.27 allows remote attackers to cause a denial of service (daemon crash) by simultaneously acquiring and giving back file callbacks, which causes the handler for the GiveUpAllCallBacks RPC to perform linked-list operations without the host_glock lock.

The bug was discovered 12/20/2007. The weakness was disclosed 01/03/2008 by Russ Allbery (Website). The advisory is shared at vupen.com. This vulnerability is known as CVE-2007-6599 since 12/31/2007. The attack can be launched remotely. The exploitation doesn't need any form of authentication. Neither technical details nor an exploit are publicly available.

It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 14 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 29908 (GLSA-200801-04 : OpenAFS: Denial of Service), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Gentoo Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 165712 (SUSE Enterprise Linux Security Update (SUSE-SR:2008:002)).
