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.
