CVE-2024-31585: FFmpeg version n5.1 to n6.1 was discovered to contain an Off-by-one Error vulnerability in libavfilter/avf_showspectrum.c.

MediumCVSS 5.3 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 21/100)

  • 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: 0.33% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. A user must open a link or visit a page. Special conditions such as timing or configuration are required.
  • Fixed version: ffmpeg (Debian:12) 7:5.1.5-0+deb12u1; ffmpeg (Debian:13) 7:7.0.1-3; ffmpeg-5 (openSUSE:Tumbleweed) 5.1.4-5.1.

Low priority for now. Upgrade to ffmpeg (Debian:12) 7:5.1.5-0+deb12u1; ffmpeg (Debian:13) 7:7.0.1-3; ffmpeg-5 (openSUSE:Tumbleweed) 5.1.4-5.1 or later.
