CVE-2005-0211: Debian Linux

High severity, CVSS 7.5. EPSS: 22.2% chance of exploitation in the next 30 days.

Buffer overflow in wccp.c in Squid 2.5 before 2.5.STABLE7 allows remote attackers to cause a denial of service and possibly execute arbitrary code via a long WCCP packet, which is processed by a recvfrom function call that uses an incorrect length parameter.

• Squid-Cache Squid: version 2.5.stable1 only; version 2.5.stable2 only; version 2.5.stable3 only; version 2.5.stable4 only; version 2.5.stable5 only; version 2.5.stable6 only
