Synopsis :

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

Description :

The remote host is affected by the vulnerability described in GLSA-200503-29
(GnuPG: OpenPGP protocol attack)

A flaw has been identified in an integrity checking mechanism of
the OpenPGP protocol.

Impact :

An automated system using GnuPG that allows an attacker to
repeatedly discover the outcome of an integrity check (perhaps by
observing the time required to return a response, or via overly verbose
error messages) could theoretically reveal a small portion of
plaintext.

Workaround :

There is no known workaround at this time.

Solution :

All GnuPG users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=app-crypt/gnupg-1.4.1'

Risk factor :

Medium / CVSS Base Score : 5.0
