Debian LTS DLA-1809-1 Moderate: libav Denial of Service Fix
debian lts
May 29, 2019
Two more security issues have been corrected in multiple demuxers and decoders of the libav multimedia library
Summary
CVE-2018-15822
The flv_write_packet function in libavformat/flvenc.c in libav did
not check for an empty audio packet, leading to an assertion failure.
CVE-2019-11338
libavcodec/hevcdec.c in libav mishandled detection of duplicate first
slices, which allowed remote attackers to cause a denial of service
(NULL pointer dereference and out-of-array access) or possibly have
unspecified other impact via crafted HEVC data.
For Debian 8 "Jessie", these problems have been fixed in version
6:11.12-1~deb8u7.
We recommend that you upgrade your libav packages.
