(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 : Low
