AI-suggested
Users should upgrade to version 3.2.1 or later once available, as the vulnerability affects versions before 3.2.1. Until then, avoid processing untrusted or malformed bitstreams that could trigger the crash. Monitor vendor advisories for official patches or updates.
Description
Fraunhofer HHI VVdeC versions before 3.2.1 have an out-of-bounds read vulnerability that can cause the decoder to crash. This occurs when attackers supply bitstreams with overlapping slice CTU coverage, leading to a negative reference index in a bi-predicted BDOF coding unit. The flaw triggers an out-of-bounds read in the Slice::getRefPic function, resulting in a denial of service via decoder crash.
