Synopsis: Moderate: squid security update
Advisory ID: RHSA-2007:0131-01
Advisory URL: https://rhn.redhat.com/errata/RHSA-2007-0131.html
Issue date: 2007-04-03
Updated on: 2007-04-03
Product: Red Hat Enterprise Linux
CVE Names: CVE-2007-1560
- ---------------------------------------------------------------------

1. Summary:

An updated squid package that fixes a security vulnerability is now
available for Red Hat Enterprise Linux 5.

This update has been rated as having moderate security impact by the Red
Hat Security Response Team.

2. Relevant releases/architectures:

RHEL Desktop Workstation (v. 5 client) - i386, x86_64
Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64

3. Problem description:

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 processed the TRACE
request method. It was possible for an attacker behind the Squid proxy
to issue a malformed TRACE request, crashing the Squid daemon child
process. As long as these requests were sent, it would prevent
legitimate usage of the proxy server. (CVE-2007-1560)

This flaw does not affect the version of Squid shipped in Red Hat
Enterprise Linux 2.1, 3, or 4.

Users of Squid should upgrade to this updated package, which contains a
backported patch and is not vulnerable to this issue.

4. Solution:

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
