CVE-2009-3765 unimportant priority: Debian including 1 source packages (mutt), 5 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): resolved 5.
mutt_ssl.c in mutt 1.5.19 and 1.5.20, when OpenSSL is used, does not properly handle a '\0' character in a domain name in the subject's Common Name (CN) field of an X.509 certificate, which allows man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority, a related issue to CVE-2009-2408.
