Ubuntu 5.04 : libnet-ssleay-perl vulnerability (USN-113-1)

Ubuntu Security Notice (C) 2005-2014 Canonical, Inc. / NASL script (C) 2006-2014 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing a security-related patch.

Description :

Javier Fernandez-Sanguino Pena discovered that this library used the
file /tmp/entropy as a fallback entropy source if a proper source was
not set in the environment variable EGD_PATH. This can potentially
lead to weakened cryptographic operations if an attacker provides a
/tmp/entropy file with known content.

The updated package requires the specification of an entropy source
with EGD_PATH and also requires that the source is a socket (as
opposed to a normal file).

Please note that this only affects systems which have egd installed
from third-party sources
egd is not shipped with Ubuntu.

Solution :

Update the affected libnet-ssleay-perl package.

Risk factor :

Medium / CVSS Base Score : 4.6
(CVSS2#AV:L/AC:L/Au:N/C:P/I:P/A:P)
