Red Hat Security Advisory

Synopsis: Low: cpio security update
Advisory ID: RHSA-2005:073-01
Advisory URL: https://rhn.redhat.com/errata/RHSA-2005-073.html
Issue date: 2005-02-15
Updated on: 2005-02-15
Product: Red Hat Enterprise Linux
CVE Names: CAN-1999-1572
---------------------------------------------------------------------

1. Summary:

An updated cpio package that fixes a umask bug is now available for Red Hat
Enterprise Linux 4.

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 4 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Enterprise Linux Desktop version 4 - i386, x86_64
Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 4 - 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.

Users of cpio should upgrade to this updated package, which resolves
this issue.

Red Hat would like to thank Mike O'Connor for bringing this issue to our
attention.
