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: 2.8% (FIRST EPSS); higher than 87% of all records.
- Fixed version: wireshark (Debian:12) 1.6.0-1; wireshark (Debian:5.0) 1.0.2-3+lenny14; wireshark (Debian:6.0) 1.2.11-6+squeeze2.
Low priority for now. Upgrade to wireshark (Debian:12) 1.6.0-1; wireshark (Debian:5.0) 1.0.2-3+lenny14; wireshark (Debian:6.0) 1.2.11-6+squeeze2 or later.
