An updated rsync package that fixes a directory traversal security flaw is now available.
Rsync is a program for synchronizing files over a network. Rsync before 2.6.1 does not properly sanitize paths when running a read/write daemon without using chroot. This could allow a remote attacker to write files outside of the module's "path", depending on the privileges assigned to the rsync daemon. Users not running an rsync daemon, running a read-only daemon, or running a chrooted daemon are not affected by this issue. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0426 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.
