CVE-2015-1872
The ff_mjpeg_decode_sof function in libavcodec/mjpegdec.c did not validate the number of components in a JPEG-LS Start Of Frame segment, which allowed remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted Motion JPEG data.
CVE-2017-14058
The read_data function in libavformat/hls.c did not restrict reload attempts for an insufficient list, which allowed remote attackers to cause a denial of service (infinite loop).
CVE-2017-1000460
In get_last_needed_nal() (libavformat/h264.c) the return value of init_get_bits was ignored and get_ue_golomb(&gb) was called on an uninitialized get_bits context, which caused a NULL deref exception.
CVE-2018-6392
The filter_slice function in libavfilter/vf_transpose.c allowed remote attackers to cause a denial of service (out-of-array access) via a crafted MP4 file.
CVE-2018-1999012
libav contained a CWE-835: Infinite loop vulnerability in pva format demuxer that could result in a vulnerability that allowed attackers to consume excessive amount of resources like CPU and RAM. This attack appeared to be exploitable via specially crafted PVA file had to be provided as input.
For Debian 8 Jessie, these problems have been fixed in version 6:11.12-1~deb8u6.
We recommend that you upgrade your libav packages.
