Squid 3.x < 3.0.STABLE26 / 3.1.15 / 3.2.0.11 Gopher Buffer Overflow

medium Nessus Plugin ID 56215

Language:

Synopsis

The remote proxy server is affected by a buffer overflow.

Description

According to its banner, the version of Squid running on the remote host is 3.x prior to 3.0.STABLE26 / 3.1.15 / 3.2.0.11. It reportedly contains a buffer overflow when parsing responses from Gopher servers that results in memory corruption and usually causes the Squid server itself to crash.

Note that Nessus has relied only on the version in the proxy server's banner, which is not updated by either of the patches the project has released to address the issue. If one of those has been applied properly and the service is restarted, consider this to be a false positive.

Solution

Upgrade to Squid version 3.0.STABLE26 / 3.1.15 / 3.2.0.11 or later.
