Posted by LinuxSecurity.com Team   
Mandrake If rsync is running in daemon mode, and not in a chrooted environment, it is possible for a remote attacker to trick rsyncd into creating an absolute pathname while sanitizing it.

Mandrakelinux Security Update Advisory
 _______________________________________________________________________

 Package name:           rsync
 Advisory ID:            MDKSA-2004:083
 Date:                   August 17th, 2004

 Affected versions:	 10.0, 9.1, 9.2, Corporate Server 2.1,
			 Multi Network Firewall 8.2
 ______________________________________________________________________

 Problem Description:

 An advisory was sent out by the rsync team regarding a security
 vulnerability in all versions of rsync prior to and including 2.6.2.
 If rsync is running in daemon mode, and not in a chrooted environment,
 it is possible for a remote attacker to trick rsyncd into creating an
 absolute pathname while sanitizing it.  This vulnerability allows a
 remote attacker to possibly read/write to/from files outside of the
 rsync directory.
 
 The updated packages are patched to prevent this problem.
