It can be used with HTTP proxies that support the ICAP protocol to implement content adaptation and filtering services. </p> </background> <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. </p> </description> <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 ">=net-proxy/c-icap-0.2.6" </code> </resolution> <references> <uri link="http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-7401">CVE-2013-7401</uri> <uri link="http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-7402">CVE-2013-7402</uri> </references> <metadata tag="requester" timestamp="Mon, 04 Aug 2014 19:33:11 +0000"> keytoaster </metadata> <metadata tag="submitter" timestamp="Fri, 19 Sep 2014 18:54:16 +0000">K_F</metadata> </glsa>
