    CONECTIVA LINUX SECURITY ANNOUNCEMENT 
    - --------------------------------------------------------------------------
    
    PACKAGE   : gnupg
    SUMMARY   : GnuPG key validity vulnerability
    DATE      : 2003-07-11 16:02:00
    ID        : CLA-2003:694
    RELEVANT
    RELEASES  : 7.0, 8, 9
    
    - -------------------------------------------------------------------------
    
    DESCRIPTION
     GnuPG[1] is a OpenPGP-compliant tool for secure communication used
     to, for example, sign emails, encrypt, decrypt and verify (signed)
     data.
     
     During the development of GnuPG 1.2.2, a bug has been found in the
     key validation code. This bug causes keys with more than one user ID
     to give all user IDs on the key the amount of validity given to the
     most-valid key. In this situation, GnuPG would not emit a warning
     when a low trust ID is used for encryption if that key also contains
     a trusted enough ID.
     
     Keys with only one ID are not affected by this problem.
     
     For Conectiva Linux 7.0 and 8, the GnuPG package has been updated to
     version 1.0.7 and includes a fix provided by the authors[2]. GnuPG in
     Conectiva Linux 9 does not need a version upgrade and includes the
     same patch.
     
    
    
    SOLUTION
     It is recommended that all GnuPG users upgrade their packages.
     
     IMPORTANT: as part of the changes introduced in GnuPG versions 1.0.7
     and later, public keys for which the user as a corresponding secret
     key are no longer automatically considered trusted. To ease the
     transition, a script called "convert-from-106" (part of GnuPG-1.2.2)
     has been included in these packages. If executed, this script will
     mark as trusted all public keys for which the current user has the
     corresponding private keys.
