Date Reported:

10 Mar 2015

Affected Packages:

mod-gnutls

Vulnerable:

Yes

Security database references:

In the Debian bugtracking system: Bug 578663.
In Mitre's CVE dictionary: CVE-2015-2091.

More information:

Thomas Klute discovered that in mod-gnutls, an Apache module providing SSL and TLS encryption with GnuTLS, a bug caused the server's client verify mode not to be considered at all, in case the directory's configuration was unset. Clients with invalid certificates were then able to leverage this flaw in order to get access to that directory.

For the stable distribution (wheezy), this problem has been fixed in version 0.5.10-1.1+deb7u1.

For the unstable distribution (sid), this problem has been fixed in version 0.6-1.3.

We recommend that you upgrade your mod-gnutls packages.
