<p>libproxy is a library for automatic proxy configuration management.</p>
<p>A boundary error when processing the proxy.pac file could cause a
stack-based buffer overflow.
<impact type="normal">
<p>A man-in-the-middle attacker could provide a specially crafted proxy.pac
file on a remote server, possibly resulting in execution of arbitrary
code with the privileges of the process or a Denial of Service condition.
<p>There is no known workaround at this time.</p>
<p>All libproxy users should upgrade to the latest version:</p>
# emerge --sync
# emerge --ask --oneshot --verbose "&gt;=net-libs/libproxy-0.4.10"
