Vulnerability Assessment Details

[GLSA-200503-29] GnuPG: OpenPGP protocol attack

Vulnerability Assessment Summary
GnuPG: OpenPGP protocol attack

Detailed Explanation for this Vulnerability Assessment
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 permits a possible hacker 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.
