Summary
Red Hat Security Advisory: cpio security update
Severity
Low
Notes
Topic: 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.
Details: 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.

CVE-1999-1572

cpio on FreeBSD 2.1.0, Debian GNU/Linux 3.0, and possibly other operating systems, uses a 0 umask when creating files using the -O (archive) or -F options, which creates the files with mode 0666 and allows local users to read or overwrite those files.

Threats
Impact Low
CVE-2005-1111

Race condition in cpio 2.6 and earlier allows local users to modify permissions of arbitrary files via a hard link attack on a file while it is being decompressed, whose permissions are changed by cpio after the decompression is complete.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
