TWCERT/CC發布日期：2005-03-04
原漏洞發布日期：2005-03-03
原漏洞最新更新日期：--
通用安全漏洞編號：CAN-2005-0446
分類：Dos,
來源參考：RHSA-2005:173-01
──── 簡述 ─────────────────────────────────
更新 squid 套件，修正阻斷服務攻擊弱點。
Red Hat Security Response Team 將此列為高度安全性更新。
──── 說明 ─────────────────────────────────
Squid 是全功能的 Web proxy cache。
Squid 在處理 FQDN 檢視時存在錯誤。利用傳送特別設計的 DNS 回應給 FQDN
檢視可能會造成 Squid 伺服器當機。CVE (cve.mitre.org) 已將此問題命名為
CAN-2005-0446 。
建議 squid 使用者更新此勘誤套件，如此即不會受此問題影響。

Red Hat Security Advisory
Synopsis: Moderate: squid security update
Advisory ID: RHSA-2005:173-01
Advisory URL: https://rhn.redhat.com/errata/RHSA-2005-173.html
Issue date: 2005-03-03
Updated on: 2005-03-03
Product: Red Hat Enterprise Linux
CVE Names: CAN-2005-0446
- - ---------------------------------------------------------------------
1. Summary:
Updated squid packages that fix a denial of service issue are now available.
This update has been rated as having important security impact by the Red
Hat Security Response Team
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

3. Problem description:
Squid is a full-featured Web proxy cache.
A bug was found in the way Squid handles FQDN lookups. It was possible
to crash the Squid server by sending a carefully crafted DNS response to
an FQDN lookup. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2005-0446 to this issue.
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. 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:
