Name of the Vulnerable Software and Affected Versions libebml2 versions prior to 2012-08-26

Description The issue allows remote attackers to cause a denial of service, resulting in a null pointer dereference and application crash, via a crafted mkv file. This is due to a problem in the EBML FindNextElement function in ebmlmain.c.

Recommendations For versions prior to 2012-08-26, consider updating to a version released after 2012-08-26 to resolve the issue. As a temporary workaround, consider restricting the use of crafted mkv files to minimize the risk of exploitation.
