CVE-2009-2730Date: (C)2009-08-12   (M)2024-02-22


libgnutls in GnuTLS before 2.8.2 does not properly handle a '' character in a domain name in the subject's (1) Common Name (CN) or (2) Subject Alternative Name (SAN) 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.
