security advisorysecurity updateRed Hat Enterprise LinuxRed Hat Enterprise Linux 3: RHSA-2005:080-01 Low: Cpio Umask Issue
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. - --------------------------------------------------------------------- Red Hat Security Advisory Synopsis: Low: cpio security update Advisory ID: RHSA-2005:080-01 Advisory URL: https://access.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 user's 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 Forinformation on how to install packages manually, refer to the following Web page for the System Administration or Customization guide specific to your system: https://docs.redhat.com/en/documentation/red_hat_enterprise_linux/10/ 5.
