Date: Mon, 1 Nov 2004 12:20:19 -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-2004:881] Conectiva Security Announcement - rsync -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- CONECTIVA LINUX SECURITY ANNOUNCEMENT - -------------------------------------------------------------------------- PACKAGE : rsync SUMMARY : Fix for path sanitation vulnerabilities DATE : 2004-11-01 12:20:00 ID : CLA-2004:881 RELEVANT RELEASES : 9, 10 - ------------------------------------------------------------------------- DESCRIPTION rsync[1] is a program used mainly to mirror files between remote sites. rsync before 2.6.1 does not properly sanitize paths[2] when running a read and write daemon without using chroot. This could allow a remote attacker to write files outside of the rsync directory, depending on rsync's daemon privileges. Also, rsync prior to version 2.6.3 has another path sanitization vulnerability[3]. This issue could allow a remote attacker to read or write files outside of the rsync directory. This vulnerability is only exploitable when an rsync daemon is running and not within a chroot, which is not the default configuration. SOLUTION It is recommended that all rsync users upgrade their packages. IMPORTANT: after the update, the rsync server must be restarted manually if it was already running.
