RHEL 4 : squid (RHSA-2006:0052)

high Nessus Plugin ID 21031

Synopsis

The remote Red Hat host is missing a security update for squid.

Description

The remote Redhat Enterprise Linux 4 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2006:0052 advisory.

Squid is a high-performance proxy caching server for Web clients, supporting FTP, gopher, and HTTP data objects.

A denial of service flaw was found in the way squid processes certain NTLM authentication requests. It is possible for a remote attacker to crash the Squid server by sending a specially crafted NTLM authentication request.
The Common Vulnerabilities and Exposures project (cve.mitre.org) assigned the name CVE-2005-2917 to this issue.

The following issues have also been fixed in this update:

* An error introduced in squid-2.5.STABLE6-3.4E.12 can crash Squid when a user visits a site that has a bit longer DNS record.

* An error introduced in the old package prevented Squid from returning correct information about large file systems. The new package is compiled with the IDENT lookup support so that users who want to use it do not have to recompile it.

* Some authentication helpers needed SETUID rights but did not have them.
If administrators wanted to use cache administrator, they had to change the SETUID bit manually. The updated package sets this bit so the new package can be updated without manual intervention from administrators.

* Squid could not handle a reply from an HTTP server when the reply began with the new-line character.

* An issue was discovered when a reply from an HTTP server was not HTTP 1.0 or 1.1 compliant.

* The updated package keeps user-defined error pages when the package is updated and it adds new ones.

All users of squid should upgrade to this updated package, which resolves these issues.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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

Solution

Update the RHEL squid package based on the guidance in RHSA-2006:0052.
