NASL family Debian Local Security Checks NASL id DEBIAN_DLA-1630.NASL description Several security vulnerabilities were corrected in the libav multimedia library which may lead to a denial of service, information disclosure or the execution of arbitrary code if a malformed file is processed. 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 does not ensure that pix_fmt is set, which 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 the vp8_decode_mb_row_no_filter and pred8x8_128_dc_8_c functions. CVE-2017-14055 denial of service in mv_read_header() due to lack of an EOF (End of File) check might cause huge CPU and memory consumption. CVE-2017-14056 denial of service in rl2_read_header() due to lack of an EOF (End of File) check might cause huge CPU and memory consumption. CVE-2017-14057 denial of service in asf_read_marker() due to lack of an EOF (End of File) check might cause huge CPU and memory consumption. CVE-2017-14170 denial of service in mxf_read_index_entry_array() due to lack of an EOF (End of File) check might cause huge CPU consumption. CVE-2017-14171 denial of service in nsv_parse_NSVf_header() due to lack of an EOF (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.
