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).
The updated packages have been patched to correct this issue.
