Summary

CVE-2015-0282

GnuTLS does not verify the RSA PKCS #1 signature algorithm to match
the signature algorithm in the certificate, leading to a potential
downgrade to a disallowed algorithm without detecting it.

CVE-2015-0294

It was reported that GnuTLS does not check whether the two signature
algorithms match on certificate import.

For the stable distribution (wheezy), these problems have been fixed in
version 2.12.20-8+deb7u3.

We recommend that you upgrade your gnutls26 packages.
