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)

Integer overflow in the gnu_special function in libiberty allows remote 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)

GNU assembler in GNU Binutils 2.28 is vulnerable to a global buffer 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…
