CVE-2017-14054 WRITEUP MEDIUM WRITEUP
FFmpeg - Denial of Service via Crafted IVR File in ivr_read_header
In libavformat/rmdec.c in FFmpeg 3.3.3, a DoS in ivr_read_header() due to lack of an EOF (End of File) check might cause huge CPU consumption. When a crafted IVR file, which claims a large "len" field in the header but does not contain sufficient backing data, is provided, the first type==4 loop would consume huge CPU resources, since there is no EOF check inside the loop.
CVSS 6.5
CVE-2017-14056 WRITEUP MEDIUM WRITEUP
FFmpeg - Denial of Service via Crafted RL2 File
In libavformat/rl2.c in FFmpeg 3.3.3, a DoS in rl2_read_header() due to lack of an EOF (End of File) check might cause huge CPU and memory consumption. When a crafted RL2 file, which claims a large "frame_count" field in the header but does not contain sufficient backing data, is provided, the loops (for offset and size tables) would consume huge CPU and memory resources, since there is no EOF check inside these loops.
CVSS 6.5
CVE-2017-14057 WRITEUP MEDIUM WRITEUP
FFmpeg - Denial of Service via ASF Header Parsing
In FFmpeg 3.3.3, a DoS in asf_read_marker() due to lack of an EOF (End of File) check might cause huge CPU and memory consumption. When a crafted ASF file, which claims a large "name_len" or "count" field in the header but does not contain sufficient backing data, is provided, the loops over the name and markers would consume huge CPU and memory resources, since there is no EOF check inside these loops.
CVSS 6.5
CVE-2017-14059 WRITEUP MEDIUM WRITEUP
FFmpeg - Denial of Service via Crafted CINE File
In FFmpeg 3.3.3, a DoS in cine_read_header() due to lack of an EOF check might cause huge CPU and memory consumption. When a crafted CINE file, which claims a large "duration" field in the header but does not contain sufficient backing data, is provided, the image-offset parsing loop would consume huge CPU and memory resources, since there is no EOF check inside the loop.
