=====================================================================

 

1. Summary:

 

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.

 

2. Relevant releases/architectures:

 

Red Hat Enterprise Linux Client (v. 7) - x86_64

Red Hat Enterprise Linux ComputeNode (v. 7) - x86_64

Red Hat Enterprise Linux Server (v. 7) - aarch64, ppc64, ppc64le, s390x, x86_64

Red Hat Enterprise Linux Workstation (v. 7) - x86_64

 

3. Description:

 

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.

 

4. Solution:
