                 Mandrakelinux Security Update Advisory
 _______________________________________________________________________

 Package name:           gnupg
 Advisory ID:            MDKSA-2005:057
 Date:                   March 15th, 2005

 Affected versions:	 10.0, 10.1, 9.2, Corporate 3.0,
			 Corporate Server 2.1
 ______________________________________________________________________

 Problem Description:

 The OpenPGP protocol is vulnerable to a timing-attack in order to
 gain plain text from cipher text.  The timing difference appears as a
 side effect of the so-called "quick scan" and is only exploitable on
 systems that accept an arbitrary amount of cipher text for automatic
 decryption.
 
 The updated packages have been patched to disable the quick check for
 all public key-encrypted messages and files.
