HighCVSS 7.5 · v2.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 31/100)

  • 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: 4.4% (FIRST EPSS); higher than 91.6% of all records.
  • No special conditions are required; it is repeatable.
  • Fixed version: mutt (Debian:12) 1.5.4-1; mutt (Debian:3.0) 1.3.28-2.1.

Low priority for now. Upgrade to mutt (Debian:12) 1.5.4-1; mutt (Debian:3.0) 1.3.28-2.1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Buffer overflow in Mutt 1.4.0 and possibly earlier versions, 1.5.x up to 1.5.3, and other programs that use Mutt code such as Balsa before 2.0.10, allows a remote malicious IMAP server to cause a denial of service (crash) and possibly execute arbitrary code via a crafted folder.
