An issue was discovered in Libav 12.3. A read access violation in the intableinit16 function in libavcodec/aacsbr.c allows remote attackers to cause a denial of service (application crash), as demonstrated by avconv.
There exists a heap-based buffer overflow in vc1decodeiblockadv in vc1block.c in Libav 12.3, which allows attackers to cause a denial-of-service via a crafted aac file.
There exists a heap-based buffer over-read in ffvc1preddc in vc1block.c in Libav 12.3, which allows attackers to cause a denial-of-service via a crafted aac file.
There exists a heap-based buffer overflow in vc1decodepmbintfi in vc1block.c in Libav 12.3, which allows attackers to cause a denial-of-service via a crafted aac file.
There exists a NULL pointer dereference in ffvc1parseframeheaderadv in vc1.c in Libav 12.3, which allows attackers to cause a denial-of-service through a crafted aac file.
An issue was discovered in Libav 12.3. A read access violation in the movprobe function in libavformat/mov.c allows remote attackers to cause a denial of service (application crash), as demonstrated by avconv.
DISPUTED An issue was discovered in Libav 12.3. An access violation allows remote attackers to cause a denial of service (application crash), as demonstrated by avconv. This is related to ffmpasynthfilterfloat in avcodec/mpegaudiodsptemplate.c. NOTE: This may be a duplicate of CVE-2018-19129.
In Libav 12.3, there is an infinite loop in the function wvreadblockheader() in the file wvdec.c.
In mpc8readheader in libavformat/mpc8.c in Libav 12.3, an input file can result in an avioseek infinite loop and hang, with 100% CPU consumption. Attackers could leverage this vulnerability to cause a denial of service via a crafted file.
An issue was discovered in Libav 12.3. Division by zero in rangedecodeculshift in libavcodec/apedec.c allows remote attackers to cause a denial of service (application crash), as demonstrated by avconv.
An issue was discovered in Libav 12.3. There is an infinite loop in the function movprobe in the file libavformat/mov.c, related to offset and tag.
DISPUTED A stack-based buffer overflow in the subtitle decoder in Libav 12.3 allows attackers to corrupt the stack via a crafted video file in Matroska format, because srttoass in libavcodec/srtdec.c misuses snprintf. NOTE: Third parties dispute that this is a vulnerability because “no evidence of a vulnerability is provided” and only “a generic warning from a static code analysis” is provided.
In Libav 12.3, a denial of service in the subtitle decoder allows attackers to hog the CPU via a crafted video file in Matroska format, because srttoass in libavcodec/srtdec.c has a complex format argument to sscanf.
A stack-based buffer overflow in the subtitle decoder in Libav 12.3 allows attackers to corrupt the stack via a crafted video file in Matroska format, because srttoass in libavcodec/srtdec.c misuses snprintf.
In Libav 12.3, there is a segmentation fault in vc1decodebmbintfr in vc1block.c that allows an attacker to cause denial-of-service via a crafted file.
In Libav 12.3, there is a heap-based buffer over-read in vc1decodepmbintfi in vc1block.c that allows an attacker to cause denial-of-service via a crafted file.
