Squid < 2.5.STABLE8 Malformed Host Name Error Message Information Disclosure

medium Nessus Plugin ID 15929

Language:

Synopsis

The remote proxy server is affected by an information disclosure vulnerability.

Description

According to its banner, the version of Squid running on the remote host is prior to 2.5.STABLE8. It is, therefore, affected by an information disclosure vulnerability due to improper handling of malformed host names. An unauthenticated, remote attacker can exploit this issue to disclose the contents of recently freed memory as error messages.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Squid version 2.5.STABLE8 or later. Alternatively, apply the vendor-supplied patch.
