Noroxi assessment
Priority: Monitor (action score 14/100)
- 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: 0.24% (FIRST EPSS).
- Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. Special conditions such as timing or configuration are required.
- Fixed version: ffmpeg (Debian:13) 7:7.0.1-3; ffmpeg-5 (openSUSE:Tumbleweed) 5.1.4-5.1.
- Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).
Low priority for now. Upgrade to ffmpeg (Debian:13) 7:7.0.1-3; ffmpeg-5 (openSUSE:Tumbleweed) 5.1.4-5.1 or later.

Root cause
When data is copied, the source length is not compared with the size of the destination buffer. Excess data overwrites adjacent memory.
