    Two more security issues have been corrected in multiple demuxers and decoders of the libav multimedia library.
    Package        : libav
    Version        : 6:11.12-1~deb8u7
    CVE ID         : CVE-2018-15822 CVE-2019-11338
    Two more security issues have been corrected in multiple demuxers and
    decoders of the libav multimedia library.
        The flv_write_packet function in libavformat/flvenc.c in libav did
        not check for an empty audio packet, leading to an assertion failure.
        libavcodec/hevcdec.c in libav mishandled detection of duplicate first
        slices, which allowed remote attackers to cause a denial of service
        (NULL pointer dereference and out-of-array access) or possibly have
        unspecified other impact via crafted HEVC data.
    For Debian 8 "Jessie", these problems have been fixed in version
    We recommend that you upgrade your libav packages.
