RHEL 2.1 / 3 : rsync (RHSA-2003:399)

high Nessus Plugin ID 12440

Synopsis

The remote Red Hat host is missing a security update.

Description

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.

Solution

Update the affected rsync package.
