MediumCVSS 5.0 · v2.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 22/100)

  • 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: 5.4% (FIRST EPSS); higher than 92.8% of all records.
  • No special conditions are required; it is repeatable.
  • Fixed version: samba (Debian:12) 3.0.7; samba (Red Hat:enterprise_linux:3::as) 0:3.0.7-1.3E; samba-client (Red Hat:enterprise_linux:3::as) 0:3.0.7-1.3E.

Low priority for now. Upgrade to samba (Debian:12) 3.0.7; samba (Red Hat:enterprise_linux:3::as) 0:3.0.7-1.3E; samba-client (Red Hat:enterprise_linux:3::as) 0:3.0.7-1.3E or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Samba 3.0.6 and earlier allows remote attackers to cause a denial of service (infinite loop and memory exhaustion) via certain malformed requests that cause new processes to be spawned and enter an infinite loop.
