    Hi

    The recent MFSA's for firefox mention the following issue as critical:

    | A double-free could have occurred in vpx_codec_enc_init_multi after a
    | failed allocation when initializing the encoder for WebRTC. This could
    | have caused memory corruption and a potentially exploitable crash.

    Cf. https://www.mozilla.org/en-US/security/advisories/mfsa2025-44/

    Fix is at: https://chromium.googlesource.com/webm/libvpx/+/1c758781c428c0e895645b95b8ff1512b6bdcecb

    MR (for unstable) is at https://salsa.debian.org/multimedia-team/libvpx/-/merge_requests/5

    Regards,
    Salvatore
