VUL-0: CVE-2017-14170: ffmpeg: DoS in mxf_read_index_entry_array() due to lack of an EOF check
Last modified: 2021-09-11 02:36:54 UTC
CVE-2017-14170 In libavformat/mxfdec.c in FFmpeg 3.3.3, a DoS in mxf_read_index_entry_array() due to lack of an EOF (End of File) check might cause huge CPU consumption. When a crafted MXF file, which claims a large "nb_index_entries" field in the header but does not contain sufficient backing data, is provided, the loop would consume huge CPU resources, since there is no EOF check inside the loop. Moreover, this big loop can be invoked multiple times if there is more than one applicable data segment in the crafted MXF file. Upstream fix: https://github.com/FFmpeg/FFmpeg/commit/900f39692ca0337a98a7cf047e4e2611071810c2 References: http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2017-14170 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-14170
Already fixed in ffmpeg2-2.8.13 submitted yesterday, but we need an ffmpeg(3) update then.
