Noroxi assessment
Priority: Monitor (action score 15/100)
- 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: 1.5% (FIRST EPSS); higher than 75.2% of all records.
- Fixed version: libxfont (Debian:12) 1:1.2.2-2; xfree86 (Debian:3.1) 4.3.0.dfsg.1-14sarge4; XFree86 (Red Hat:enterprise_linux:2.1::as) 0:4.1.0-82.EL.
Low priority for now. Upgrade to libxfont (Debian:12) 1:1.2.2-2; xfree86 (Debian:3.1) 4.3.0.dfsg.1-14sarge4; XFree86 (Red Hat:enterprise_linux:2.1::as) 0:4.1.0-82.EL or later.
