    Package        : aom
    CVE ID         : CVE-2024-5171

    An integer overflow was discovered in aom, the AV1 Video Codec Library,
    which could potentially result in the execution of arbitrary code if a
    malformed media file is processed.

    For the stable distribution (bookworm), this problem has been fixed in
    version 3.6.0-1+deb12u1.

    We recommend that you upgrade your aom packages.

    For the detailed security status of aom please refer to
    its security tracker page at:
    https://security-tracker.debian.org/tracker/aom
