    CVE ID         : CVE-2023-49465 CVE-2023-49467 CVE-2023-49468


    Three issues have been found in libde265, an open H.265 video codec
    implementation. All issues are related to heap-buffer-overflow or global
    buffer overflow in different functions.



    For Debian 10 buster, these problems have been fixed in version
    1.0.11-0+deb10u6.

    We recommend that you upgrade your libde265 packages.
