RHSA-2007:1130 - Security Advisory

Synopsis

Moderate: squid security update

Type/Severity

Security Advisory: Moderate

Topic

Updated squid packages that fix a security issue are now available for Red
Hat Enterprise Linux 2.1, 3, 4 and 5.

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

Description

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

A flaw was found in the way squid stored HTTP headers for cached objects
in system memory. An attacker could cause squid to use additional memory,
and trigger high CPU usage when processing requests for certain cached
objects, possibly leading to a denial of service. (CVE-2007-6239)

Users of squid are advised to upgrade to these updated packages, which
contain a backported patch to resolve this issue.

Solution

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

This update is available via Red Hat Network. Details on how to use
the Red Hat Network to apply this update are available at
