(Mandrake Issues Fix) Squid Input Validation Error in Processing WCCP Messages Lets Remote Users Crash Squid
SecurityTracker Alert ID:  1012979
SecurityTracker URL:  http://securitytracker.com/id/1012979
CVE Reference:   CVE-2005-0095   (Links to External Site)
Date:  Jan 25 2005
Impact:   Denial of service via network
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): 2.5
Description:   A denial of service vulnerability was reported in Squid in the processing of WCCP messages. A remote user can cause Squid to crash.

The vendor reported that a remote user can send specially crafted WCCP_I_SEE_YOU packet with the 'number of caches' field set to a value outside of the 1 - 32 range and with a spoofed address. If WCCP is enabled on the target system (which is not the default setting), Squid may crash.

Impact:   A remote user can cause Squid to crash.
Solution:   Mandrake has released a fix.

 Package name:           squid
 Advisory ID:            MDKSA-2005:014
 Date:                   January 24th, 2005

 Affected versions:	 10.0, 10.1, 9.2, Corporate Server 2.1,
			 Corporate Server 3.0
 ______________________________________________________________________

 Problem Description:

 "infamous41md" discovered two vulnerabilities in the squid proxy
 cache server.  The first is a buffer overflow in the Gopher response
 parser which leads to memory corruption and would usually crash squid
 (CAN-2005-0094).  The second is an integer overflow in the receiver of
 WCCP (Web Cache Communication Protocol) messages.  An attacker could
 send a specially crafted UDP datagram that would cause squid to crash
 (CAN-2005-0095).
 
 The updated packages have been patched to prevent these problems.
