Debian Security Advisory
DLA-1809-1 libav -- LTS security update
- Date Reported:
- 29 May 2019
- Affected Packages:
- Security database references:
- In Mitre's CVE dictionary: CVE-2018-15822, CVE-2019-11338.
- More information:
Two more security issues have been corrected in multiple demuxers and decoders of the libav multimedia library.
The flv_write_packet function in libavformat/flvenc.c in libav did not check for an empty audio packet, leading to an assertion failure.
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.
