CVE-2014-8542
libavcodec/utils.c omitted a certain codec ID during enforcement of alignment, which allowed remote attackers to cause a denial of ervice (out-of-bounds access) or possibly have unspecified other impact via crafted JV data.
CVE-2015-1207
Double-free vulnerability in libavformat/mov.c allowed remote attackers to cause a denial of service (memory corruption and crash) via a crafted .m4a file.
CVE-2017-7863
libav had an out-of-bounds write caused by a heap-based buffer overflow related to the decode_frame_common function in libavcodec/pngdec.c.
CVE-2017-7865
libav had an out-of-bounds write caused by a heap-based buffer overflow related to the ipvideo_decode_block_opcode_0xA function in libavcodec/interplayvideo.c and the avcodec_align_dimensions2 function in libavcodec/utils.c.
CVE-2017-14169
In the mxf_read_primer_pack function in libavformat/mxfdec.c in, an integer signedness error might have occurred when a crafted file, claiming a large item_num field such as 0xffffffff, was provided. As a result, the variable item_num turned negative, bypassing the check for a large value.
CVE-2017-14223
In libavformat/asfdec_f.c a DoS in asf_build_simple_index() due to lack of an EOF (End of File) check might have caused huge CPU consumption. When a crafted ASF file, claiming a large ict field in the header but not containing sufficient backing data, was provided, the for loop would have consumed huge CPU and memory resources, since there was no EOF check inside the loop.
For Debian 8 Jessie, these problems have been fixed in version 6:11.12-1~deb8u5.
We recommend that you upgrade your libav packages.
