<title>rsync: Potential integer overflow</title>
An attacker having write access to an rsync module might be able to execute
arbitrary code on an rsync server.

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.
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">
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.
Do not provide write access to an rsync module to untrusted
All rsync users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=net-misc/rsync-2.6.8&quot;</code>
