GLSA-200503-29 : GnuPG: OpenPGP protocol attack

Medium Nessus Plugin ID 17616


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


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.


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