TW-CA-2005-023-[RHSA-2005:080-01: Low: cpio security update]
────────────────────────────────────────
TWCERT/CC發布日期：2005-02-25
原漏洞發布日期：2005-02-18
原漏洞最新更新日期：--
通用安全漏洞編號：CAN-1999-1572
分類：Gain Privilege
來源參考：RHSA-2005:080-01
──── 簡述 ─────────────────────────────────
更新 cpio 套件，修正 umask 錯誤並支援超過 2GB 的大型檔案。
Red Hat Security Response Team 將此列為低度安全性更新。
──── 說明 ─────────────────────────────────
GNU cpio 將檔案複製到 cpio 或 tar 壓縮檔。
cpio 用到 -O 壓縮選項產生新檔時會使用 0 umask，儘管有使用者的 umask 設定，
仍產出權限為 0666 的檔案(皆可讀寫)。CVE (cve.mitre.org) 已將此問題命名為
CAN-1999-1572。
建議 cpio 使用者更新此勘誤套件，解決此問題與支援超過 2GB 的大型檔案。

Red Hat Security Advisory
Synopsis: Low: cpio security update
Advisory ID: RHSA-2005:080-01
Advisory URL: https://rhn.redhat.com/errata/RHSA-2005-080.html
Issue date: 2005-02-18
Updated on: 2005-02-18
Product: Red Hat Enterprise Linux
Keywords: cpio umask
CVE Names: CAN-1999-1572
- - ---------------------------------------------------------------------
1. Summary:
An updated cpio package that fixes a umask bug and supports large files
(>2GB) is now available.
This update has been rated as having low security impact by the Red Hat
Security Response Team
2. Relevant releases/architectures:
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:
GNU cpio copies files into or out of a cpio or tar archive.
It was discovered that cpio uses a 0 umask when creating files using the -O
(archive) option. This creates output files with mode 0666 (all can read
and write) regardless of the users umask setting. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CAN-1999-1572 to this issue.
All users of cpio should upgrade to this updated package, which resolves
this issue, and adds support for large files (> 2GB).
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. Bug IDs fixed (http://bugzilla.redhat.com/):
145720 - CAN-1999-1572 cpio insecure file creation
