Detailsinfo

A vulnerability was found in ProFTPD 1.3.1/1.3.2/1.3.3 (File Transfer Software). It has been classified as critical. This affects an unknown function of the component mod_tls. The manipulation with an unknown input leads to a cryptographic issue vulnerability. CWE is classifying the issue as CWE-310. This is going to have an impact on integrity, and availability. The summary by CVE is:

The mod_tls module in ProFTPD before 1.3.2b, and 1.3.3 before 1.3.3rc2, 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, which allows remote attackers to bypass intended client-hostname restrictions via a crafted certificate issued by a legitimate Certification Authority, a related issue to CVE-2009-2408.
