Mandrake 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).

 Mandriva Linux Security Advisory                       MDVSA-2008:227-1
 http://www.mandriva.com/security/
 _______________________________________________________________________

 Package : gnutls
 Date    : November 17, 2008
 Affected: 2008.0, 2008.1, 2009.0
 _______________________________________________________________________

 Problem Description:

 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.
