CVE-2009-1390 Information

Description

Mutt 1.5.19 when linked against (1) OpenSSL (mutt_ssl.c) or (2) GnuTLS (mutt_ssl_gnutls.c) allows connections when only one TLS certificate in the chain is accepted instead of verifying the entire chain which allows remote attackers to spoof trusted servers via a man-in-the-middle attack.
