PACKAGE : rsync
SUMMARY : Fix for path sanitation vulnerabilities

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.
