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

+ <background>
+ <p>
+ 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>
+ </background>
+ <description>
+ <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.
+ </p>
+ </description>
+ <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 "&gt;=net-misc/rsync-2.6.8"</code>
