+ <description>
+ <p>
+ A flaw has been identified in an integrity checking mechanism of
+ the OpenPGP protocol.
+ </p>
+ </description>
+ <impact type="low">
+ <p>
+ 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.
+ </p>
+ </impact>
+ <workaround>
+ <p>
+ There is no known workaround at this time.
+ </p>
+ </workaround>
+ <resolution>
+ <p>
+ All GnuPG users should upgrade to the latest version:
+ </p>
+ <code>
+ # emerge --sync
+ # emerge --ask --oneshot --verbose "&gt;=app-crypt/gnupg-1.4.1"</code>
