Vulnerability Assessment Details

RHSA-2003-399: rsync

Vulnerability Assessment Summary
Check for the version of the rsync packages

Detailed Explanation for this Vulnerability Assessment

Updated rsync packages are now available that fix a heap overflow in the
Rsync server.

rsync is a program for sychronizing files over the network.

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
CVE-2003-0962 to this issue.

All users should upgrade to these erratum packages containing version
2.5.7 of rsync, which is not vulnerable to this issue.

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

/sbin/chkconfig --list rsync

If the rsync server has been enabled but is not required, it can be
disabled by running the following command as root:

/sbin/chkconfig rsync off

Red Hat would like to thank the rsync team for their rapid response and
quick fix for this issue.
