Name of the Vulnerable Software and Affected Versions libde265 versions prior to 1.0.20

Description An open source implementation of the h.265 video codec contains an issue where a crafted H.265 bitstream can trigger an out-of-bounds array write within the decoder context::process reference picture set() function. This occurs due to a missing aggregate bound check on predicted short-term reference picture set entries. While individual list sizes are validated, the combined count after predicted RPS construction can exceed the 16-entry PocStFoll array, resulting in a write at index 16.

Recommendations Update to version 1.0.20.
