[slackware-security]  rsync (SSA:2004-285-01)

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 *)
