--
Summary:
This event is generated when an attempt is made to exploit a denial of
service associated with Squid Web Cache Communication Protocol (WCCP).

--
Impact:
A successful attack can cause the Squid web cache server process to
terminate.

--
Detailed Information:
A vulnerability exists in the way that a Squid server handles a WCCP
message.  A WCCP I_SEE_YOU message that contains an invalid number of
web cache entries can create an out-of-bounds array reference.  This may
result in a read access violation of memory, causing a denial of service.

--
Affected Systems:
	Squid Web Proxy Cache 2.5 STABLE7 and prior versions

--
Attack Scenarios:
An attacker can craft a WCCP I_SEE_YOU message with an invalid number of
web cache entries, causing the web cache server process to terminate.

--
Ease of Attack:
Simple.

--
False Positives:
None known.

--
False Negatives:
None known.

--
Corrective Action:
Upgrade to the most current non-affected version of the product.
