"This update for ffmpeg fixes the following issues :

CVE-2018-13300: An improper argument passed to the
avpriv_request_sample function may have triggered an out-of-array read
while converting a crafted AVI file to MPEG4, leading to a denial of
service and possibly an information disclosure (bsc#1100348)

CVE-2018-15822: The flv_write_packet function did not check for an
empty audio packet, leading to an assertion failure and DoS
(bsc#1105869)

CVE-2018-13305: Due to a missing check for negative values of the
mquant variable, the vc1_put_blocks_clamped function in
libavcodec/vc1_block.c may trigger an out-of-array access while
converting a crafted AVI file to MPEG4, leading to an information
disclosure or a denial of service. (bsc#1100345).

CVE-2018-12458: An improper integer type in the
mpeg4_encode_gop_header function in libavcodec/mpeg4videoenc.c might
have triggered an assertion violation while converting a crafted AVI
file to MPEG4, leading to a denial of service. (bsc#1097983).

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
