More information:

Multiple vulnerabilities have been discovered in GnuTLS, a library implementing the TLS and SSL protocols. The Common Vulnerabilities and Exposures project identifies the following problems:

  • CVE-2014-8155

    Missing date/time checks on CA certificates

  • 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

    GnuTLS does not check whether the two signature algorithms match on certificate import.

For Debian 6 Squeeze, these issues have been fixed in gnutls26 version 2.8.6-1+squeeze5
