Description


A vulnerability has been reported in Squid, which can be exploited by malicious people to cause a DoS (Denial of Service).

The vulnerability is caused due to an error within the "strHdrAcptLangGetItem()" function (errorpage.cc) when handling the "Accept-Language" header. This can be exploited to trigger an infinite loop and consume CPU resources subsequently stopping responses to clients.

The vulnerability is reported in versions 3.2 through 3.2.8 and 3.3 through 3.3.2.


Solution:
Update to version 3.2.9 or 3.3.3 or apply a patch (please see the vendor's advisory for details).
