rsync is a server and client utility that provides fast
|
|
incremental file transfers. It is used to efficiently synchronize files
|
|
between hosts and is used by emerge to fetch Gentoo's Portage tree.

<p>
|
|
An integer overflow was found in the receive_xattr function from
|
|
the extended attributes patch (xattr.c) for rsync. The vulnerable
|
|
function is only present when the "acl" USE flag is set.
|
|

|
<impact type="high">
|
|
<p>
|
|
A remote attacker with write access to an rsync module could craft
|
|
malicious extended attributes which would trigger the integer overflow,
|
|
potentially resulting in the execution of arbitrary code with the
|
|
rights of the rsync daemon.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
Do not provide write access to an rsync module to untrusted
|
|
parties.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All rsync users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=net-misc/rsync-2.6.8"</code>
|
|
