Debian DSA-1925-1 : proftpd-dfsg - insufficient input validation

medium Nessus Plugin ID 44790

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

It has been discovered that proftpd-dfsg, a virtual-hosting FTP daemon, does not properly handle a '\0' character in a domain name in the Subject Alternative Name field of an X.509 client certificate, when the dNSNameRequired TLS option is enabled.

Solution

Upgrade the proftpd-dfsg packages.

For the stable distribution (lenny), this problem has been fixed in version 1.3.1-17lenny4.

For the oldstable distribution (etch), this problem has been fixed in version 1.3.0-19etch3.

Binaries for the amd64 architecture will be released once they are available.
