A libnet-ssleay-perl security update is available for Ubuntu Linux 5.04

===========================================================
Ubuntu Security Notice USN-113-1 May 03, 2005
libnet-ssleay-perl vulnerability
CAN-2005-0106
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 5.04 (Hoary Hedgehog)

The following packages are affected:

libnet-ssleay-perl

The problem can be corrected by upgrading the affected package to version 1.25-1ubuntu0.2. In general, a standard system upgrade is sufficient to effect the necessary changes.



Details follow:

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 3rd third party sources; egd is not shipped with Ubuntu.
