AI analysisSummaries by Vani AI
Fraunhofer HHI VVdeC before 3.2.1 has an out-of-bounds read in Slice::getRefPic. A local attacker who can get a user to decode a crafted bitstream can mark a CTU in a second slice so a bi-predicted BDOF coding unit has a negative reference index. The decoder then reads past m_apcRefPicList and crashes. Limited information disclosure is also possible.
What to do: Upgrade Fraunhofer HHI VVdeC to 3.2.1 or later. No workaround is stated.

Description · NVD
Fraunhofer HHI VVdeC before 3.2.1 contains an out-of-bounds read vulnerability that allows attackers to crash the decoder by supplying bitstreams with overlapping slice CTU coverage. Attackers can code a CTU in a second slice so a bi-predicted BDOF coding unit carries a negative reference index, causing Slice::getRefPic to read outside m_apcRefPicList and crash decoding.
