Several security issues were fixed in libav, a multimedia library for
processing audio and video files.

CVE-2017-17127

    The vc1_decode_frame function in libavcodec/vc1dec.c allows remote
    attackers to cause a denial of service (NULL pointer dereference
    and application crash) via a crafted file.
    CVE-2018-19130 is a duplicate of this vulnerability.

CVE-2017-18245

    The mpc8_probe function in libavformat/mpc8.c allows remote
    attackers to cause a denial of service (heap-based buffer
    over-read) via a crafted audio file on 32-bit systems.

CVE-2018-19128

    Heap-based buffer over-read in decode_frame in libavcodec/lcldec.c
    allows an attacker to cause denial-of-service via a crafted avi
    file.

CVE-2019-14443

    Division by zero in range_decode_culshift in libavcodec/apedec.c
    allows remote attackers to cause a denial of service (application
    crash), as demonstrated by avconv.

CVE-2019-17542

    Heap-based buffer overflow in vqa_decode_chunk because of an
    out-of-array access in vqa_decode_init in libavcodec/vqavideo.c.

For Debian 8 "Jessie", these problems have been fixed in version
6:11.12-1~deb8u9.

We recommend that you upgrade your libav packages.
