Detail
| Problem Description: An updated squid package that fixes a remote denial of service vulnerability is now avaliable. 2. Relevant releases/architectures: Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - i386, ia64 Red Hat Linux Advanced Workstation 2.1 - ia64 Red Hat Enterprise Linux ES version 2.1 - i386 Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Desktop version 3 - i386, x86_64 Red Hat Enterprise Linux ES version 3 - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 3 - i386, ia64, x86_64 3. Problem description: Squid is a full-featured Web proxy cache. iDEFENSE reported a flaw in the squid SNMP module. This flaw could allow an attacker who has the ability to send arbitrary packets to the SNMP port to restart the server, causing it to drop all open connections. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0918 to this issue. All users of squid should update to this erratum package, which contains a backport of the security fix for this vulnerability. 4. Solution: Before applying this update, make sure that all previously-released errata relevant to your system have been applied. Use Red Hat Network to download and update your packages. To launch the Red Hat Update Agent, use the following command: up2date For information on how to install packages manually, refer to the following Web page for the System Administration or Customization guide specific to your system: http://www.redhat.com/docs/manuals/enterprise/ 5.
