<background>
<p>c-icap is an implementation of an ICAP server. It can be used with HTTP
proxies that support the ICAP protocol to implement content adaptation
and filtering services.

<description>
<p>c-icap contains a flaw in the parse_request() function of request.c that
may allow a remote denial of service. The issue is triggered when the
buffer fails to contain a ‘ ‘ or ‘?’ symbol, which will cause the
end pointer to increase and surpass allocated memory. With a specially
crafted request (e.g. via the OPTIONS method), a remote attacker can
cause a loss of availability for the program.

<impact type="normal">
<p>A remote attacker may cause a Denial of Service condition.</p>
</impact>
<workaround>
<p>There is no known workaround at this time.</p>
</workaround>
<resolution>
<p>All c-icap users should upgrade to the latest version:</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose "&gt;=net-proxy/c-icap-0.2.6"
</code>
</resolution>
