Ubuntu 5.04 / 5.10 / 6.06 LTS : openssl vulnerability (USN-339-1)

Ubuntu Security Notice (C) 2006-2013 Canonical, Inc. / NASL script (C) 2007-2013 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related patches.

Description :

Philip Mackenzie, Marius Schilder, Jason Waddle and Ben Laurie of
Google Security discovered that the OpenSSL 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.

Solution :

Update the affected packages.

Risk factor :

Medium / CVSS Base Score : 5.8
(CVSS2#AV:N/AC:M/Au:N/C:N/I:P/A:P)
