NO FIX YET · SEE WHAT TO DO
VVdeC, Fraunhofer HHI's VVC video decoder, dereferences a NULL pointer in InterPrediction::xPredInterBlk when a new SPS enables reference wrap-around. An attacker who supplies a crafted VVC bitstream can crash the decoder, causing denial of service.

It checks your repository and tells you if you’re affected, with the fix.
Applications that embed VVdeC and decode VVC bitstreams, especially those that accept streams from untrusted sources. Apps that never decode VVC or only decode trusted content can skip it.

3.2.1).3.2.1.Fraunhofer HHI VVdeC through 3.2.1 contains a NULL pointer dereference vulnerability in InterPrediction::xPredInterBlk that allows attackers to crash the decoder by switching SPS to enable reference wrap-around. Attackers can supply a crafted VVC bitstream activating a new SPS with sps_ref_wraparound_enabled_flag set, causing reads from missing PIC_RECON_WRAP buffers and denial of service.
