rsync (SSA:2004-285-01)
Posted on: 10/12/2004 08:32 AM

New rsync 2.6.3 packages are available for Slackware 8.1, 9.0, 9.1, 10.0, and -current to a fix security issue when rsync is run as a non-chrooted server.

More details about this issue may be found in the Common Vulnerabilities and Exposures (CVE) database:

http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-792

Here are the details from the Slackware 10.0 ChangeLog:
+--------------------------+
patches/packages/rsync-2.6.3-i486-1.tgz: Upgraded to rsync-2.6.3.
From the rsync NEWS file:
A bug in the sanitize_path routine (which affects a non-chrooted
rsync daemon) could allow a user to craft a pathname that would get
transformed into an absolute path for certain options (but not for
file-transfer names). If you're running an rsync daemon with chroot
disabled, *please upgrade*, ESPECIALLY if the user privs you run
rsync under is anything above "nobody".
Note that rsync, in daemon mode, sets the "use chroot" to true by
default, and (in this default mode) is not vulnerable to this issue.
I would strongly recommend against setting "use chroot" to false
even if you've upgraded to this new package.
(* Security fix *)
