Squid 3.x < 3.2.9 / 3.3.3 strHdrAcptLangGetItem Malformed Accept-Language Denial of Service

high Nessus Plugin ID 65601

Language:

Synopsis

The remote proxy server is affected by a denial of service vulnerability.

Description

According to its banner, the version of Squid running on the remote host is 3.2.x prior to 3.2.9 or 3.3.x prior to 3.3.3 and is, therefore, affected by a denial of service vulnerability. An error exists in the function 'strHdrAcptLangGetItem' in the file 'errorpage.cc' that could allow certain 'Accept-Language' HTTP headers to cause a denial of service condition.

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

Solution

Either upgrade to Squid version 3.2.9 / 3.3.3 or later, or apply the vendor-supplied patch.
