Message-ID: <200307111934.QAA24199@frajuto.distro.conectiva> Date: Fri, 11 Jul 2003 16:34:35 -0300 From: Conectiva Updates <secure@...ectiva.com.br> To: conectiva-updates@...aleguas.conectiva.com.br, lwn@....net, bugtraq@...urityfocus.com, security-alerts@...uxsecurity.com, linsec@...ts.seifried.org Subject: [CLA-2003:694] Conectiva Security Announcement - gnupg -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- 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.
