The remote host is affected by the vulnerability described in GLSA-201612-24 (Binutils: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Binutils. Please review       the CVE identifiers referenced below for details.
  Impact :

    A remote attacker could entice a user to open a specially crafted file,       possibly resulting in execution of arbitrary code with the privileges of       the process, cause a Denial of Service condition, or overwrite arbitrary       files.
  Workaround :

    There is no known workaround at this time.

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.

  - The ld linker on 64-bit PowerPC now correctly checks the     output format when asked to produce a binary in another     format than PowerPC.

  - 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.

  - Undesirable runtime relocations described in     SLBA-2015:0974.

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.

  - Expressions of the form: 'FUNC@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.

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.

A buffer overflow flaw was found in the way various binutils utilities processed certain files. If a user were tricked into processing a specially crafted file, it could cause the utility used to process that file to crash or, potentially, execute arbitrary code with the privileges of the user running that utility.

An integer overflow flaw was found in the way the strings utility processed certain files. If a user were tricked into running the strings utility on a specially crafted file, it could cause the strings executable to crash.

A stack-based buffer overflow flaw was found in the SREC parser of the libbfd library. A specially crafted file could cause an application using the libbfd library to crash or, potentially, execute arbitrary code with the privileges of the user running that application.

A heap-based buffer overflow flaw was found in the way certain binutils utilities processed archive files. If a user were tricked into processing a specially crafted archive file, it could cause the utility used to process that archive to crash or, potentially, execute arbitrary code with the privileges of the user running that utility.

A stack-based buffer overflow flaw was found in the way various binutils utilities processed certain files. If a user were tricked into processing a specially crafted file, it could cause the utility used to process that file to crash or, potentially, execute arbitrary code with the privileges of the user running that utility.

A stack-based buffer overflow flaw was found in the way objdump processed IHEX files. A specially crafted IHEX file could cause objdump to crash or, potentially, execute arbitrary code with the privileges of the user running objdump.

It was found that the fix for the CVE-2014-8485 issue was incomplete:
a heap-based buffer overflow in the objdump utility could cause it to crash or, potentially, execute arbitrary code with the privileges of the user running objdump when processing specially crafted files.

Updated binutils packages that fix multiple security issues, several bugs, and add various enhancements are now available for Red Hat Enterprise Linux 7.

Multiple security issues have been found in binutils, a toolbox for binary file manipulation. These vulnerabilities include multiple memory safety errors, buffer overflows, use-after-frees and other implementation errors may lead to the execution of arbitrary code, the bypass of security restrictions, path traversal attack or denial of service.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Michal Zalewski discovered that the setup_group function in libbfd in GNU binutils did not properly check group headers in ELF files. An attacker could use this to craft input that could cause a denial of service (application crash) or possibly execute arbitrary code.
(CVE-2014-8485)

Hanno Bock discovered that the _bfd_XXi_swap_aouthdr_in function in libbfd in GNU binutils allowed out-of-bounds writes. An attacker could use this to craft input that could cause a denial of service (application crash) or possibly execute arbitrary code.
(CVE-2014-8501)

Hanno Bock discovered a heap-based buffer overflow in the pe_print_edata function in libbfd in GNU binutils. An attacker could use this to craft input that could cause a denial of service (application crash) or possibly execute arbitrary code.
(CVE-2014-8502)

Alexander Cherepanov discovered multiple directory traversal vulnerabilities in GNU binutils. An attacker could use this to craft input that could delete arbitrary files. (CVE-2014-8737)

Alexander Cherepanov discovered the _bfd_slurp_extended_name_table function in libbfd in GNU binutils allowed invalid writes when handling extended name tables in an archive. An attacker could use this to craft input that could cause a denial of service (application crash) or possibly execute arbitrary code. (CVE-2014-8738)

Hanno Bock discovered a stack-based buffer overflow in the ihex_scan function in libbfd in GNU binutils. An attacker could use this to craft input that could cause a denial of service (application crash).
(CVE-2014-8503)

Michal Zalewski discovered a stack-based buffer overflow in the srec_scan function in libbfd in GNU binutils. An attacker could use this to to craft input that could cause a denial of service (application crash); the GNU C library's Fortify Source printf protection should prevent the possibility of executing arbitrary code.
(CVE-2014-8504)

Michal Zalewski discovered that the srec_scan function in libbfd in GNU binutils allowed out-of-bounds reads. An attacker could use this to craft input to cause a denial of service. This issue only affected Ubuntu 14.04 LTS, Ubuntu 12.04 LTS, and Ubuntu 10.04 LTS.
(CVE-2014-8484)

Sang Kil Cha discovered multiple integer overflows in the
_objalloc_alloc function and objalloc_alloc macro in binutils. This could allow an attacker to cause a denial of service (application crash). This issue only affected Ubuntu 12.04 LTS and Ubuntu 10.04 LTS. (CVE-2012-3509)

Alexander Cherepanov and Hanno Bock discovered multiple additional out-of-bounds reads and writes in GNU binutils. An attacker could use these to craft input that could cause a denial of service (application crash) or possibly execute arbitrary code. A few of these issues may be limited in exposure to a denial of service (application abort) by the GNU C library's Fortify Source printf protection.

The strings(1) utility in GNU binutils used libbfd by default when examining executable object files; unfortunately, libbfd was not originally developed with the expectation of hostile input. As a defensive measure, the behavior of strings has been changed to default to 'strings --all' behavior, which does not use libbfd; use the new argument to strings, '--data', to recreate the old behavior.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Multiple vulnerabilities has been found and corrected in binutils :

Multiple integer overflows in the (1) _objalloc_alloc function in objalloc.c and (2) objalloc_alloc macro in include/objalloc.h in GNU libiberty, as used by binutils 2.22, allow remote attackers to cause a denial of service (crash) via vectors related to the addition of CHUNK_HEADER_SIZE to the length, which triggers a heap-based buffer overflow (CVE-2012-3509).

The srec_scan function in bfd/srec.c in libdbfd in GNU binutils before 2.25 allows remote attackers to cause a denial of service (out-of-bounds read) via a small S-record (CVE-2014-8484).

The setup_group function in bfd/elf.c in libbfd in GNU binutils 2.24 and earlier allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via crafted section group headers in an ELF file (CVE-2014-8485).

The _bfd_XXi_swap_aouthdr_in function in bfd/peXXigen.c in GNU binutils 2.24 and earlier allows remote attackers to cause a denial of service (out-of-bounds write) and possibly have other unspecified impact via a crafted NumberOfRvaAndSizes field in the AOUT header in a PE executable (CVE-2014-8501).

Heap-based buffer overflow in the pe_print_edata function in bfd/peXXigen.c in GNU binutils 2.24 and earlier allows remote attackers to cause a denial of service (crash) and possibly have other unspecified impact via a truncated export table in a PE file (CVE-2014-8502).

Stack-based buffer overflow in the ihex_scan function in bfd/ihex.c in GNU binutils 2.24 and earlier allows remote attackers to cause a denial of service (crash) and possibly have other unspecified impact via a crafted ihex file (CVE-2014-8503).

Stack-based buffer overflow in the srec_scan function in bfd/srec.c in GNU binutils 2.24 and earlier allows remote attackers to cause a denial of service (crash) and possibly have other unspecified impact via a crafted file (CVE-2014-8504).

Multiple directory traversal vulnerabilities in GNU binutils 2.24 and earlier allow local users to delete arbitrary files via a .. (dot dot) or full path name in an archive to (1) strip or (2) objcopy or create arbitrary files via (3) a .. (dot dot) or full path name in an archive to ar (CVE-2014-8737).

The _bfd_slurp_extended_name_table function in bfd/archive.c in GNU binutils 2.24 and earlier allows remote attackers to cause a denial of service (invalid write, segmentation fault, and crash) via a crafted extended name table in an archive (CVE-2014-8738).

The updated packages provides a solution for these security issues.

binutils has been updated to fix eight security issues :

  - Lack of range checking leading to controlled write in
    _bfd_elf_setup_sections(). (CVE-2014-8485)

  - Invalid read flaw in libbfd. (CVE-2014-8484)

  - Write to uninitialized memory in the PE parser.
    (CVE-2014-8501)

  - Crash in the PE parser. (CVE-2014-8502)

  - Segfault in the ihex parser when it encounters a     malformed ihex file. (CVE-2014-8503)

  - Stack buffer overflow in srec_scan. (CVE-2014-8504)

  - Out-of-bounds memory write while processing a crafted     'ar' archive. (CVE-2014-8738)

  - Directory traversal vulnerability allowing random file     deletion/creation. (CVE-2014-8737)

Multiple security issues have been found in binutils, a toolbox for binary file manipulation. These vulnerabilities include multiple memory safety errors, buffer overflows, use-after-frees and other implementation errors may lead to the execution of arbitrary code, the bypass of security restrictions, path traversal attack or denial of service.
