Description Agostino Sarubbo gentoo-dev 2014-03-04 09:40:36 UTC
From ${URL} :


Some vulnerabilities have been reported in GnuTLS, which can be exploited by malicious people to conduct 
spoofing attacks.

The vulnerabilities are caused due to some unspecified errors when verifying certificates and can be 
exploited to bypass certain certificate validation checks and subsequently e.g. spoof a server.

The vulnerabilities are reported in versions 3.x prior to 3.2.12 and prior to 3.1.22 and versions 2.x.

Update to a fixed version or apply patch.

Further details available to Secunia VIM customers

Reported by the vendor.

Original Advisory:

@maintainer(s): after the bump, in case we need to stabilize the package, please let us know if it is ready for the stabilization or not.
Comment 1 Hanno Böck gentoo-dev 2014-03-04 13:04:38 UTC
3.12.2 is already in the tree, but ~-only. For gnutls 2.x, there's no update available, but a patch from upstream.

So we need either a patched 2.x-ebuild or stabilize 3.12.2.

gnutls-2.12.23-r3 in tree with patch[1]

Sorry, yet another CVE at bug#501282, please stabilize gnutls-2.12.23-r4 which contains both.

CVE-2014-0092 (
  lib/x509/verify.c in GnuTLS before 3.1.22 and 3.2.x before 3.2.12 does not
  properly handle unspecified errors when verifying X.509 certificates from
  SSL servers, which allows man-in-the-middle attackers to spoof servers via a
  crafted certificate.
