Noroxi assessment

Priority: Monitor (action score 18/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 2.5% (FIRST EPSS); higher than 85.2% of all records.
  • Fixed version: ffmpeg (Debian:12) 7:2.4.1-1; ffmpeg (Debian:6.0) 4:0.5.8-1.

Low priority for now. Upgrade to ffmpeg (Debian:12) 7:2.4.1-1; ffmpeg (Debian:6.0) 4:0.5.8-1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

The dv_extract_audio function in libavcodec in FFmpeg 0.7.x before 0.7.12 and 0.8.x before 0.8.11 and in Libav 0.5.x before 0.5.9, 0.6.x before 0.6.6, 0.7.x before 0.7.5, and 0.8.x before 0.8.1 allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via a crafted DV file.
