A vulnerability classified as critical has been found in Novell Moonlight 2.0/2.3.0/2.4/2.31/3.99. Affected is an unknown functionality of the file Array.Copy. The manipulation with an unknown input leads to a race condition vulnerability. CWE is classifying the issue as 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. This is going to have an impact on integrity, and availability. CVE summarizes:

Race condition in the FastCopy optimization in the Array.Copy method in metadata/icall.c in Mono, when Moonlight 2.x before 2.4.1 or 3.x before 3.99.3 is used, allows remote attackers to trigger a buffer overflow and modify internal data structures, and cause a denial of service (plugin crash) or corrupt the internal state of the security manager, via a crafted media file in which a thread makes a change after a type check but before a copy action.

The weakness was shared 04/13/2011 by Basti (Website). The advisory is available at github.com. This vulnerability is traded as CVE-2011-0990. It is possible to launch the attack remotely.
