1. Summary:

 

Updated binutils packages that fix multiple security issues, several bugs,

and add various enhancements are now available for Red Hat Enterprise

Linux 7.

 

Red Hat Product Security has rated this update as having Moderate security

impact. Common Vulnerability Scoring System (CVSS) base scores, which give

detailed severity ratings, are available for each vulnerability from the

CVE links in the References section.

 

2. Relevant releases/architectures:

 

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

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

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

Red Hat Enterprise Linux ComputeNode Optional (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 binutils packages provide a set of binary utilities.

 

Multiple buffer overflow flaws were found in the libbdf library used by

various binutils utilities. If a user were tricked into processing a

specially crafted file with an application using the libbdf library, it

could cause the application to crash or, potentially, execute arbitrary

code. (CVE-2014-8485, CVE-2014-8501, CVE-2014-8502, CVE-2014-8503,

CVE-2014-8504, CVE-2014-8738)

 

An integer overflow flaw was found in the libbdf library used by various

binutils utilities. If a user were tricked into processing a specially

crafted file with an application using the libbdf library, it could cause

the application to crash. (CVE-2014-8484)

 

A directory traversal flaw was found in the strip and objcopy utilities.

A specially crafted file could cause strip or objdump to overwrite an

arbitrary file writable by the user running either of these utilities.

(CVE-2014-8737)

 

This update fixes the following bugs:

 

* Binary files started by the system loader could lack the Relocation

Read-Only (RELRO) protection even though it was explicitly requested when

the application was built. This bug has been fixed on multiple

architectures. Applications and all dependent object files, archives, and

libraries built with an alpha or beta version of binutils should be rebuilt

to correct this defect. (BZ#1200138, BZ#1175624)

 

* The ld linker on 64-bit PowerPC now correctly checks the output format

when asked to produce a binary in another format than PowerPC. (BZ#1226864)

 

* An important variable that holds the symbol table for the binary being

debugged has been made persistent, and the objdump utility on 64-bit

PowerPC is now able to access the needed information without reading an

invalid memory region. (BZ#1172766)

 

* Undesirable runtime relocations described in RHBA-2015:0974. (BZ#872148)

 

The update adds these enhancements:

 

* New hardware instructions of the IBM z Systems z13 are now supported by

assembler, disassembler, and linker, as well as Single Instruction,

Multiple Data (SIMD) instructions. (BZ#1182153)

 

* Expressions of the form: "FUNC ( -at -) localentry" to refer to the local entry

point for the FUNC function (if defined) are now supported by the PowerPC

assembler. These are required by the ELFv2 ABI on the little-endian variant

of IBM Power Systems. (BZ#1194164)

 

All binutils users are advised to upgrade to these updated packages, which

contain backported patches to correct these issues and add these

enhancements.

 

4. Solution:

 

Before applying this update, make sure all previously released errata

relevant to your system have been applied.
