Squid < 3.0STABLE24 HTCP Request Denial of Service
Medium Log Correlation Engine Plugin ID 801037
The remote host is vulnerable to a Denial of Service (DoS) attack.
According to its banner, the version of Squid proxy caching server installed on the remote host is 2.x or 3.0.x earlier than 3.0.STABLE24. Such versions are potentially affected by a denial-of-service vulnerability due to incorrect processing of specially crafted HTCP packets.
Either upgrade to Squid version 3.0.STABLE24 or later, or apply the patch referenced in the project's advisory above.
