CVE-2018-14394 CVE-2018-1999010
Several security vulnerabilities were corrected in the libav
multimedia library which may lead to a denial-of-service, information
disclosure or the execution of arbitrary code if a malformed file is
processed.
CVE-2017-9993
Libav does not properly restrict HTTP Live Streaming filename
extensions and demuxer names, which allows attackers to read
arbitrary files via crafted playlist data.
CVE-2017-9994
libavcodec/webp.c in Libav does not ensure that pix_fmt is set,
which allows remote attackers to cause a denial of service
(heap-based buffer overflow and application crash) or possibly have
unspecified other impact via a crafted file, related to the
vp8_decode_mb_row_no_filter and pred8x8_128_dc_8_c functions.
CVE-2017-14055
Denial-of-service in mv_read_header() due to lack of an EOF (End of
File) check might cause huge CPU and memory consumption.
CVE-2017-14056
Denial-of-service in rl2_read_header() due to lack of an EOF
(End of File) check might cause huge CPU and memory consumption.
CVE-2017-14057
Denial-of-service in asf_read_marker() due to lack of an EOF
(End of File) check might cause huge CPU and memory consumption.
CVE-2017-14170
Denial-of-service in mxf_read_index_entry_array() due to lack of an
EOF (End of File) check might cause huge CPU consumption.
CVE-2017-14171
Denial-of-service in nsv_parse_NSVf_header() due to lack of an EOF
(End of File) check might cause huge CPU consumption.
CVE-2017-14767
The sdp_parse_fmtp_config_h264 function in
libavformat/rtpdec_h264.c mishandles empty sprop-parameter-sets
values, which allows remote attackers to cause a denial of service
(heap buffer overflow) or possibly have unspecified other impact via
a crafted sdp file.
CVE-2017-15672
The read_header function in libavcodec/ffv1dec.c allows remote
attackers to have unspecified impact via a crafted MP4 file, which
triggers an out-of-bounds read.
CVE-2017-17130
The ff_free_picture_tables function in libavcodec/mpegpicture.c
allows remote attackers to cause a denial of service
(heap-based buffer overflow and application crash) or possibly have
unspecified other impact via a crafted file, related to
vc1_decode_i_blocks_adv.
CVE-2018-6621
The decode_frame function in libavcodec/utvideodec.c in Libav allows
remote attackers to cause a denial of service (out of array read)
via a crafted AVI file.
CVE-2018-7557
The decode_init function in libavcodec/utvideodec.c in
Libav allows remote attackers to cause a denial of service
(Out of array read) via an AVI file with crafted dimensions within
chroma subsampling data.
CVE-2018-14394
libavformat/movenc.c in Libav allows attackers to cause a
denial of service (application crash caused by a divide-by-zero
error) with a user crafted Waveform audio file.
CVE-2018-1999010
Libav contains multiple out of array access vulnerabilities in the
mms protocol that can result in attackers accessing out of bound
data.
For Debian 8 "Jessie", these problems have been fixed in version
6:11.12-1~deb8u4.
We recommend that you upgrade your libav packages.
