CVE-2005-0095

Description:
infamous41md has reported two vulnerabilities in Squid, which can be exploited by malicious people to cause a DoS (Denial of Service) or potentially compromise a vulnerable system.
1) An error in the handling of invalid field values in "WCCP_I_SEE_YOU" messages can be exploited to crash Squid by sending a specially crafted UDP datagram with a spoofed WCCP (Web Cache Communication Protocol) router's IP address.
Successful exploitation requires that WCCP is enabled (not default setting).
2) A boundary error in the "gopherToHTML()" function can be exploited via a malicious gopher server to cause a buffer overflow by responding with a specially crafted, overly long line.
Successful exploitation may allow execution of arbitrary code.
Solution:
Apply patches for 2.5.STABLE7:
http://www.squid-cache.org/Versions/v...2.5.STABLE7-gopher_html_parsing.patch
http://www.squid-cache.org/Versions/v....STABLE7-wccp_denial_of_service.patch
