530719 - CVE-2009-3639 ProFTPD: Doesn't properly handle NULL character in subjectAltName

This update fixes CVE-2009-3639, in which proftpd's mod_tls, when the dNSNameRequired TLS option is enabled, does not properly handle a '\0' character in a domain name in the Subject Alternative Name field of an X.509 client certificate. This allows remote attackers to bypass intended client-hostname restrictions via a crafted certificate issued by a legitimate Certification Authority. This update to upstream release 1.3.2b also fixes the following issues recorded in the proftpd bug tracker at bugs.proftpd.org: - Regression causing command-line define options not to work (bug 3221) - Use correct cached user values with "SQLNegativeCache on" (bug 3282) - Slower transfers of multiple small files (bug 3284) - Support MaxTransfersPerHost, MaxTransfersPerUser properly (bug 3287) - Handle symlinks to directories with trailing slashes properly (bug 3297)...
