"Martin von Gagern found a flow in how GnuTLS versions 1.2.4 up until
2.6.1 verified certificate chains provided by a server. A malicious
server could use this flaw to spoof its identity by tricking client
applications that used the GnuTLS library to trust invalid
certificates (CVE-2008-4989).

Update :

It was found that the previously-published patch to correct this issue
caused a regression when dealing with self-signed certificates. An
updated patch that fixes the security issue and resolves the
regression issue has been applied to these packages."
