Memory corruption via unchecked HRD count
Published Apr 6, 2022 · Updated Aug 2, 2024
Heap-based buffer overflow in libde265 1.0.8 and earlier allows remote authenticated users to corrupt decoder memory via crafted HEVC data. The VUI HRD parser accepts cpb_cnt_minus1 values above 31, then continues processing instead of returning the range error to the sequence-parameter-set reader. The affected application must pass attacker-controlled HEVC VUI HRD data to the library; the public record does not establish a specific post-corruption outcome.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
