Date: Wed, 30 Apr 2003 18:45:13 -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-2003:635] Conectiva Security Announcement - balsa -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- CONECTIVA LINUX SECURITY ANNOUNCEMENT - -------------------------------------------------------------------------- PACKAGE : balsa SUMMARY : Buffer overflow in the IMAP code DATE : 2003-04-30 18:44:00 ID : CLA-2003:635 RELEVANT RELEASES : 9 - ------------------------------------------------------------------------- DESCRIPTION Balsa is a GNOME email client. It includes code from mutt, wich is a text-mode email client. An update[1] for mutt with a fix for a buffer overflow vulnerability[2] (CAN-2003-0140) in the code that handles IMAP folders was released in March 14th, 2003. The mutt version distributed with Conectiva Linux 9 (mutt-1.5.4-28732cl) is not vulnerable to this issue, but balsa versions <= 1.2 incorporate the same code from the old mutt, thus being also vulnerable (Conectiva Linux 9 includes the package balsa-2.0.9-29085cl). An attacker who is able to control an IMAP server accessed by balsa can exploit this vulnerability to remotely crash the client or execute arbitrary code with the privileges of the user running it. This update fixes this vulnerability. SOLUTION All balsa users should upgrade. Please note that it is necessary to restart the balsa program (if it is already running) after the upgrade in order to run the new installed version.
