Sebastian Krahmer from the SUSE Security Team discovered two off-by-one
errors in the function "f_name()" in file sender.c when processing
overly long directory names.

<impact type="normal">
<p>
A remote attacker could entice a user to synchronize a repository
containing specially crafted directories, leading to the execution of
arbitrary code with the privileges of the user running the application.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All rsync users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=net-misc/rsync-2.6.9-r3&quot;</code>
</resolution>
