Mandriva Linux Security Advisory : gnutls (MDVSA-2008:227-1)
Medium Nessus Plugin ID 36960
SynopsisThe remote Mandriva Linux host is missing one or more security updates.
DescriptionMartin 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).
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.
SolutionUpdate the affected packages.
