RHEL 7 : cpio (RHSA-2015:2108)

medium Nessus Plugin ID 86969

Language:

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

Updated cpio packages that fix one security issue and two bugs are now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

The cpio packages provide the GNU cpio utility for creating and extracting archives, or copying files from one place to another.

A heap-based buffer overflow flaw was found in cpio's list_file() function. An attacker could provide a specially crafted archive that, when processed by cpio, would crash cpio, or potentially lead to arbitrary code execution. (CVE-2014-9112)

This update fixes the following bugs :

* Previously, during archive creation, cpio internals did not detect a read() system call failure. Based on the premise that the call succeeded, cpio terminated unexpectedly with a segmentation fault without processing further files. The underlying source code has been patched, and an archive is now created successfully. (BZ#1138148)

* Previously, running the cpio command without parameters on Red Hat Enterprise Linux 7 with Russian as the default language resulted in an error message that was not accurate in Russian due to an error in spelling. This has been corrected and the Russian error message is spelled correctly. (BZ#1075513)

All cpio users are advised to upgrade to these updated packages, which contain backported patches to correct these issues.

Solution

Update the affected cpio and / or cpio-debuginfo packages.
