<description>
|
|
<p>
|
|
A flaw has been identified in an integrity checking mechanism of
|
|
the OpenPGP protocol.
|
|
</p>

|
<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 ">=app-crypt/gnupg-1.4.1"</code>
