libav: Multiple issues (4.2)
Last modified: 2019-01-16 13:40:09 CET
New Debian libav 6:11.12-1~deb8u4 fixes: This update addresses the following issues: * CVE-2017-9993: Libav does not properly restrict HTTP Live Streaming filename extensions and demuxer names, which allows attackers to read arbitrary files via crafted playlist data. * CVE-2017-9994: libavcodec/webp.c in Libav before does not ensure that pix_fmt is set, which allows remote attackers to cause a denial of service unspecified other impact via a crafted file, related to the vp8_decode_mb_row_no_filter and pred8x8_128_dc_8_c functions. * CVE-2017-14055: a DoS in mv_read_header() due to lack of an end-of-file check might cause huge CPU and memory consumption. * CVE-2017-14056: a DoS in rl2_read_header() due to lack of an end-of-file check might cause huge CPU consumption. * CVE-2017-14057: a DoS in asf_read_marker() due to lack of an end-of-file check might cause huge CPU and memory consumption. * CVE-2017-14170: a DoS in mxf_read_index_entry_array() due to lack of an end-of-file check might cause huge CPU consumption. * CVE-2017-14171: a DoS in nsv_parse_NSVf_header() due to lack of an end-of-file check might cause huge CPU consumption. * CVE-2017-14767: The sdp_parse_fmtp_config_h264 function in libavformat/rtpdec_h264.c mishandles empty sprop-parameter-sets values, which allows remote attackers to cause a denial of service (heap buffer overflow) or possibly have unspecified other impact via a crafted sdp file. * CVE-2017-15672: The read_header function in libavcodec/ffv1dec.c allows remote attackers to have unspecified impact via a crafted MP4 file, which triggers an out-of-bounds read. * CVE-2017-17130: The ff_free_picture_tables function in libavcodec/mpegpicture.c allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted file, related to vc1_decode_i_blocks_adv. * CVE-2018-6621: The decode_frame function in libavcodec/utvideodec.c in Libav allows remote attackers to cause a denial of service (out of array read) via a crafted AVI file. * CVE-2018-7557: The decode_init function in libavcodec/utvideodec.c in Libav allows remote attackers to cause a denial of service (out of array read) via an AVI file with crafted dimensions within chroma subsampling data. * CVE-2018-14394: libavformat/movenc.c in Libav allows attackers to cause a denial of service (application crash caused by a divide-by-zero error) with a user crafted Waveform audio file. * CVE-2018-1999010: Libav contains multiple out of array access vulnerabilities in the mms protocol that can result in attackers accessing out of bound data.
