    Ubuntu: GnuTLS vulnerability

    Date 16 Oct 2006
    3660
    Posted By LinuxSecurity Advisories
    The GnuTLS library did not sufficiently check the padding of PKCS #1 v1.5 signatures if the exponent of the public key is 3 (which is widely used for CAs). This could be exploited to forge signatures without the need of the secret key.
    =========================================================== 
    Ubuntu Security Notice USN-348-1         September 18, 2006
    gnutls11, gnutls12 vulnerability
    CVE-2006-4790
    ===========================================================
    
    A security issue affects the following Ubuntu releases:
    
    Ubuntu 5.04
    Ubuntu 5.10
    Ubuntu 6.06 LTS
    
    This advisory also applies to the corresponding versions of
    Kubuntu, Edubuntu, and Xubuntu.
    
    The problem can be corrected by upgrading your system to the
    following package versions:
    
    Ubuntu 5.04:
      libgnutls11                              1.0.16-13ubuntu0.3
    
    Ubuntu 5.10:
      libgnutls11                              1.0.16-13.1ubuntu1.2
    
    Ubuntu 6.06 LTS:
      libgnutls11                              1.0.16-14ubuntu1.1
      libgnutls12                              1.2.9-2ubuntu1.1
    
    After a standard system upgrade you need to reboot your computer to
    effect the necessary changes.
    
    Details follow:
    
    The GnuTLS library did not sufficiently check the padding of PKCS #1
    v1.5 signatures if the exponent of the public key is 3 (which is
    widely used for CAs). This could be exploited to forge signatures
    without the need of the secret key.
