USN-113-1: libnet-ssleay-perl vulnerability

Releases

• Ubuntu 5.04

Details

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.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 5.04

• libnet-ssleay-perl -

In general, a standard system update will make all the necessary changes.
