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.
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.
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.
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 an infinite loop in the function wvreadblockheader() in the file wvdec.c.
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.
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.
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.
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.
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.
In Libav 12.3, there is a heap-based buffer over-read in vc1decodebmbintfi in vc1block.c that allows an attacker to cause denial-of-service via a crafted file.
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.
