Common Weakness Enumeration (CWE)

CWE-125 - Out-of-bounds Read

Common Attack Pattern Enumeration and Classification (CAPEC)

Overread Buffers
An adversary attacks a target by providing input that causes an application to read beyond the boundary of a defined buffer. This typically occurs when a value influencing where to start or stop reading is set to reflect positions outside of the valid memory location of the buffer. This type of attack may result in exposure of sensitive information, a system crash, or arbitrary code execution.

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. For Debian 8
