libav: Multiple issues (4.2)
Last modified: 2017-11-21 13:56:05 CET
Upstream Debian package version 6:11.9-1~deb8u1 fixes: * Multiple integer overflows have been discovered in libav 11.8 and earlier, allowing remote attackers to cause a crash via a crafted MP3 file (CVE-2016-9821 CVE-2016-9822)
6:11.11-1~deb8u1 fixes: * The smka_decode_frame function in libavcodec/smacker.c in FFmpeg before 2.6.5, 2.7.x before 2.7.3, and 2.8.x through 2.8.2 does not verify that the data size is consistent with the number of channels, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted Smacker data. (CVE-2015-8365) * The decode_residual function in libavcodec in libav 9.21 allows remote attackers to cause a denial of service (buffer over-read) or obtain sensitive information from process memory via a crafted h264 video file. (CVE-2017-7208) * FFmpeg before 2017-02-07 has an out-of-bounds write caused by a heap-based buffer overflow related to the decode_frame function in libavcodec/pictordec.c. (CVE-2017-7862) * Heap-based buffer overflow in the decode_dds1 function in libavcodec/dfa.c in FFmpeg before 2.8.12, 3.0.x before 3.0.8, 3.1.x before 3.1.8, 3.2.x before 3.2.5, and 3.3.x before 3.3.1 allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted file. (CVE-2017-9992)
Imported, advisory: libav.yaml
we have 6:11.9-1~deb8u1 in errata 4.2-2, but the fixed version is 6:11.11-1~deb8u1
Ok Philipp fixed the tool and imported 6:11.11-1~deb8u1.
OK
