Detail
| Problem Description: An updated cpio package that fixes multiple issues 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 (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 WS version 2.1 - i386 3. Problem description: GNU cpio copies files into or out of a cpio or tar archive. A race condition bug was found in cpio. It is possible for a local malicious user to modify the permissions of a local file if they have write access to a directory in which a cpio archive is being extracted. The Common Vulnerabilities and Exposures project has assigned the name CVE-2005-1111 to this issue. 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 users can read and write) regardless of the user's umask setting. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-1999-1572 to this issue. All users of cpio are advised to upgrade to this updated package, which contains backported fixes for these issues. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. This update is available via Red Hat Network. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. 5. Bug IDs fixed (http://bugzilla.redhat.com/): 169760 - CVE-2005-1111 Race condition in cpio 172191 - CVE-1999-1572 cpio insecure file creation |
