Description

This update provides the latest stable binutils, currently version 2.32
and fixes at least the following security issues:

ihex.c in GNU Binutils before 2.26 contains a stack buffer overflow when
printing bad bytes in Intel Hex objects (CVE-2014-9939)

Use-after-free vulnerability in libiberty allows remote attackers to cause
a denial of service (segmentation fault and crash) via a crafted binary,
related to "btypevec." (CVE-2016-4487)

Use-after-free vulnerability in libiberty allows remote attackers to cause
a denial of service (segmentation fault and crash) via a crafted binary,
related to "ktypevec." (CVE-2016-4488)

attackers to cause a denial of service (segmentation fault and crash) via
a crafted binary, related to the "demangling of virtual tables."
(CVE-2016-4489)

Integer overflow in cp-demangle.c in libiberty allows remote attackers to
cause a denial of service (segmentation fault and crash) via a crafted
binary, related to inconsistent use of the long and int types for lengths.
(CVE-2016-4490)

Buffer overflow in the do_type function in cplus-dem.c in libiberty allows
remote attackers to cause a denial of service (segmentation fault and
crash) via a crafted binary. (CVE-2016-4492)

The demangle_template_value_parm and do_hpacc_template_literal functions
in cplus-dem.c in libiberty allow remote attackers to cause a denial of
service (out-of-bounds read and crash) via a crafted binary. 
(CVE-2016-4493)

The demangler in GNU Libiberty allows remote attackers to cause a denial
of service (infinite loop, stack overflow, and crash) via a cycle in the
references of remembered mangled types. (CVE-2016-6131)

readelf in GNU Binutils 2.28 writes to illegal addresses while processing
corrupt input files containing symbol-difference relocations, leading to
a heap-based buffer overflow. (CVE-2017-6965)

readelf in GNU Binutils 2.28 has a use-after-free (specifically
read-after-free) error while processing multiple, relocated sections in an
MSP430 binary. This is caused by mishandling of an invalid symbol index,
and mishandling of state across invocations. (CVE-2017-6966)

readelf in GNU Binutils 2.28 is vulnerable to a heap-based buffer over-read
while processing corrupt RL78 binaries. The vulnerability can trigger
program crashes. It may lead to an information leak as well. (CVE-2017-6969)

The dump_section_as_bytes function in readelf in GNU Binutils 2.28 accesses
a NULL pointer while reading section contents in a corrupt binary, leading
to a program crash. (CVE-2017-7209)

objdump in GNU Binutils 2.28 is vulnerable to multiple heap-based buffer
over-reads (of size 1 and size 8) while handling corrupt STABS enum type
strings in a crafted object file, leading to program crash. (CVE-2017-7210)

overflow (of size 1) while attempting to unget an EOF character from the
input stream, potentially leading to a program crash. (CVE-2017-7223)

The find_nearest_line function in objdump in GNU Binutils 2.28 is vulnerable
to an invalid write (of size 1) while disassembling a corrupt binary that
contains an empty function name, leading to a program crash. (CVE-2017-7224)

The find_nearest_line function in addr2line in GNU Binutils 2.28 does not
handle the case where the main file name and the directory name are both
empty, triggering a NULL pointer dereference and an invalid write, and
leading to a program crash. (CVE-2017-7225)

The pe_ILF_object_p function in the Binary File Descriptor (BFD) library
(aka libbfd), as distributed in GNU Binutils 2.28, is vulnerable to a
heap-based buffer over-read of size 4049 because it uses the strlen
function instead of strnlen, leading to program crashes in several
utilities such as addr2line, size, and strings. It could lead to
information disclosure as well. (CVE-2017-7226)

GNU linker (ld) in GNU Binutils 2.28 is vulnerable to a heap-based buffer
overflow while processing a bogus input script, leading to a program
crash. This relates to lack of '\0' termination of a name field in ldlex.l.
(CVE-2017-7227)

The Binary File Descriptor (BFD) library (aka libbfd), as distributed in
GNU Binutils 2.28, has an invalid read (of size 8) because the code to
emit relocs (bfd_elf_final_link function in bfd/elflink.c) does not check
the format of the input file before trying to read the ELF reloc section
header. The vulnerability leads to a GNU linker (ld) program crash.
(CVE-2017-7299)

leading to a GNU linker (ld) program crash. (CVE-2017-7300)

The Binary File Descriptor (BFD) library (aka libbfd), as distributed in
GNU Binutils 2.28, has an aout_link_add_symbols function in bfd/aoutx.h

the string offset. The vulnerability could lead to a GNU linker (ld)
program crash. (CVE-2017-7301)

The Binary File Descriptor (BFD) library (aka libbfd), as distributed in
GNU Binutils 2.28, has a swap_std_reloc_out function in bfd/aoutx.h that

for relocs that could not be recognised. This vulnerability causes
Binutils utilities like strip to crash. (CVE-2017-7302)

The Binary File Descriptor (BFD) library (aka libbfd), as distributed in
GNU Binutils 2.28, is vulnerable to an invalid read (of size 4) because

distributed in GNU Binutils 2.28, has a "member access within null
pointer" undefined behavior issue, which might allow remote attackers to
cause a denial of service (application crash) or possibly have unspecified
other impact via an "int main() {return 0;}" program. (CVE-2017-7614)

The Binary File Descriptor (BFD) library (aka libbfd), as distributed in
GNU Binutils 2.28, is vulnerable to an invalid read of size 8 because of
missing a check to determine whether symbols are NULL in the

that conduct an analysis of binary programs using the libbfd library,
such as objdump, to crash. (CVE-2017-8392)

The Binary File Descriptor (BFD) library (aka libbfd), as distributed in
GNU Binutils 2.28, is vulnerable to a global buffer over-read error
because of an assumption made by code that runs for objcopy and strip,
that SHT_REL/SHR_RELA sections are always named starting with a 
.rel/.rela prefix. This vulnerability causes programs that conduct an
analysis of binary programs using the libbfd library, such as objcopy
and strip, to crash. (CVE-2017-8393)

GNU Binutils 2.28, is vulnerable to an invalid read of size 1 and an
invalid write of size 1 during processing of a corrupt binary containing
reloc(s) with negative addresses. This vulnerability causes programs that
