CVE-2018-18483

The get_count function in cplus-dem.c in GNU libiberty, as distributed in GNU Binutils 2.31, allows remote attackers to cause a denial of service (malloc called with the result of an integer-overflowing calculation) or possibly have unspecified other impact via a crafted string, as demonstrated by c++filt.

Update to binutils 2.32:

• The binutils now support for the C-SKY processor series.
• The x86 assembler now supports a -mvexwig=[0|1] option to control encoding of VEX.W-ignored (WIG) VEX instructions. It also has a new -mx86-used-note=[yes|no] option to generate (or not) x86 GNU property notes.
• The MIPS assembler now supports the Loongson EXTensions R2 (EXT2), the Loongson EXTensions (EXT) instructions, the Loongson Content Address Memory (CAM) ASE and the Loongson MultiMedia extensions Instructions (MMI) ASE.
• The addr2line, c++filt, nm and objdump tools now have a default limit on the maximum amount of recursion that is allowed whilst demangling strings. This limit can be disabled if necessary.
• Objdump's --disassemble option can now take a parameter, specifying the starting symbol for disassembly. Disassembly will continue from this symbol up to the next symbol or the end of the function.
• The BFD linker will now report property change in linker map file when merging GNU properties.
• The BFD linker's -t option now doesn't report members within archives, unless -t is given twice. This makes it more useful when generating a list of files that should be packaged for a …

It was discovered that libiberty incorrectly handled parsing certain binaries. If a user or automated system were tricked into processing a specially crafted binary, a remote attacker could use this issue to cause libiberty to crash, resulting in a denial of service, or possibly execute arbitrary code
