Package : libav Version : 6:11.12-1~deb8u8 CVE ID : CVE-2017-9987 CVE-2018-5766 CVE-2018-11102 CVE-2019-14372 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.
