CVE-2019-14442
Several security issues have been corrected in multiple demuxers and
decoders of the libav multimedia library.
CVE-2017-9987
In Libav, there was a heap-based buffer overflow in the function
hpel_motion in mpegvideo_motion.c. A crafted input could have lead to
a remote denial of service attack.
CVE-2018-5766
In Libav there was an invalid memcpy in the av_packet_ref function of
libavcodec/avpacket.c. Remote attackers could have leveraged this
vulnerability to cause a denial of service (segmentation fault) via a
crafted avi file.
CVE-2018-11102
A read access violation in the mov_probe function in
libavformat/mov.c allowed remote attackers to cause a denial of
service (application crash), as demonstrated by avconv.
CVE-2019-14372
In Libav, there was an infinite loop in the function
wv_read_block_header() in the file wvdec.c.
CVE-2019-14442
In mpc8_read_header in libavformat/mpc8.c, an input file could have
resulted in an avio_seek infinite loop and hang, with 100% CPU
consumption. Attackers could have leveraged this vulnerability to
cause a denial of service via a crafted file.
For Debian 8 "Jessie", these problems have been fixed in version
6:11.12-1~deb8u8.
We recommend that you upgrade your libav packages.
