RHSA-2004:436 - Security Advisory

Topic

An updated rsync package that fixes a path sanitizing bug is now available.

Description

The rsync program synchronizes files over a network.

Versions of rsync up to and including version 2.6.2 contain a path
sanitization issue. This issue could allow an attacker to read or write
files outside of the rsync directory. This vulnerability is only
exploitable when an rsync server is enabled and is not running within a
chroot. The Common Vulnerabilities and Exposures project (cve.mitre.org)
has assigned the name CAN-2004-0792 to this issue.

Users of rsync are advised to upgrade to this updated package, which
contains a backported patch and is not affected by this issue.
