Description Mark J. Cox 2003-12-04 08:45:07 UTC

A heap overflow bug exists in Rsync versions prior to 2.5.7.  On
machines where the Rsync server has been enabled, a remote attacker
could use this flaw to execute arbitrary code as an unprivileged user.
 The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2003-0962 to this issue.

Our upgrade erratum packages will contain version 2.5.7 of Rsync which
is not vulnerable to this issue.

The Rsync server is disabled (off) by default in Red Hat Enterprise
Linux.  To check if the Rsync server has been enabled (on), run:

   /sbin/chkconfig --list rsync

If the Rsync server has been enabled but is not required it can be
disabled by running as root:

   /sbin/chkconfig rsync off
