What is CVE-2017-14057?
CVE-2017-14057 is a medium-severity denial of service vulnerability in Ffmpeg Ffmpeg, published on 31 Aug 2017. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official description
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.
Weakness: CWE-834
