Attackers can craft IMC or IAC audio files that drive freebits negative, causing the reduction loop to never terminate and consuming 100% CPU.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":6.8,"severity":"medium","source":"CNA: VulnCheck","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},{"score":5.5,"severity":"medium","source":"CNA: VulnCheck","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.1"}],"modifiedAt":1794258418891,"publishedAt":1794251451514,"references":[{"source":"CNA: VulnCheck","tags":["issue-tracking"],"url":"https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/25696"},{"source":"CNA: VulnCheck","tags":["patch"],"url":"https://github.com/FFmpeg/FFmpeg/commit/9b26bb4c9a4457d480899a1bf64ec080eceb1acd"},{"source":"CNA: VulnCheck","tags":["technical-description"],"url":"https://github.com/FFmpeg/FFmpeg/blob/n9.0.2/libavcodec/imc.c#L572"},{"source":"CNA: VulnCheck","tags":["product"],"url":"https://github.com/FFmpeg/FFmpeg"},{"source":"CNA: VulnCheck","tags":["third-party-advisory"],"url":"https://www.vulncheck.com/advisories/ffmpeg-through-9.0.2-infinite-loop-denial-of-service-via-imc-iac-decoder"}],"remediation":[{"kind":"fix","source":"CNA: VulnCheck","text":"The reporting source identifies this reference as a patch.
