Ubuntu Security Notice (C) 2006-2015 Canonical, Inc. / NASL script (C) 2007-2015 Tenable Network Security, Inc.
The remote Ubuntu host is missing one or more security-related patches.
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.
Update the affected packages.
Risk factor :
Medium / CVSS Base Score : 5.0
CVSS Temporal Score : 4.3
Public Exploit Available : false
