16 Jun 2009 — 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. Mutt v1.5.º9, enlazado contra (1) OpenSSL (mutt_ssl.c) o (2) GnuTLS (mutt_ssl_gnutls.c), permite conexiones cuando se acepta un certificado TLS en la cadena en vez de verificar esta última, lo que permite a atacantes re... • http://dev.mutt.org/hg/mutt/rev/64bf199c8d8a • CWE-287: Improper Authentication •
