GLSA-200408-17 : rsync: Potential information leakage

medium Nessus Plugin ID 14573

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200408-17 (rsync: Potential information leakage)

The paths sent by the rsync client are not checked thoroughly enough.
It does not affect the normal send/receive filenames that specify what files should be transferred. It does affect certain option paths that cause auxiliary files to be read or written.
Impact :

When rsyncd is used without chroot ('use chroot = false' in the rsyncd.conf file), this vulnerability could allow the listing of arbitrary files outside module's path and allow file overwriting outside module's path on rsync server configurations that allows uploading. Both possibilities are exposed only when chroot option is disabled.
Workaround :

You should never set the rsync daemon to run with 'use chroot = false'.

Solution

All users should update to the latest version of the rsync package.
# emerge sync # emerge -pv '>=net-misc/rsync-2.6.0-r3' # emerge '>=net-misc/rsync-2.6.0-r3'
