Noroxi assessment
Priority: Monitor (action score 29/100)
- 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: 6.7% (FIRST EPSS); higher than 94% of all records.
- Fixed version: tiff (Debian:12) 4.0.2-4; tiff (Debian:6.0) 3.9.4-5+squeeze6; libtiff (Red Hat:enterprise_linux:5::client) 0:3.8.2-18.el5_8.
Low priority for now. Upgrade to tiff (Debian:12) 4.0.2-4; tiff (Debian:6.0) 3.9.4-5+squeeze6; libtiff (Red Hat:enterprise_linux:5::client) 0:3.8.2-18.el5_8 or later.
