Date: Thu, 11 Nov 2004 15:17:12 -0200 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-2004:889] Conectiva Security Announcement - sasl2 -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- CONECTIVA LINUX SECURITY ANNOUNCEMENT - -------------------------------------------------------------------------- PACKAGE : sasl2 SUMMARY : Fix for buffer overflow vulnerability DATE : 2004-11-11 15:16:00 ID : CLA-2004:889 RELEVANT RELEASES : 9, 10 - ------------------------------------------------------------------------- DESCRIPTION SASL[1] is the Simple Authentication and Security Layer, a method for adding authentication support to connection-based protocols. A vulnerability[2] has been discovered in the Cyrus implementation of the SASL library. The library honors the environment variable SASL_PATH blindly, which allows a local attacker to link against a malicious library to run arbitrary code with the privileges of a setuid or setgid application. SOLUTION It is recommended that all sasl2 users upgrade their packages. IMPORTANT: If you are using Conectiva Linux 9, it is important to restart saslauthd daemon after upgrading the packages, in order to really fix the vulnerability.
