Description

This update provides the binutils 2.33.1 and fixes at least the
following security issues:

An issue was discovered in GNU libiberty, as distributed in GNU Binutils
2.32. simple_object_elf_match in simple-object-elf.c does not check for a
zero shstrndx value, leading to an integer overflow and resultant heap-
based buffer overflow (CVE-2019-14250).

find_abstract_instance in dwarf2.c in the Binary File Descriptor (BFD)
library (aka libbfd), as distributed in GNU Binutils 2.32, allows remote
attackers to cause a denial of service (infinite recursion and application
crash) via a crafted ELF file )CVE-2019-17450).

An issue was discovered in the Binary File Descriptor (BFD) library (aka
libbfd), as distributed in GNU Binutils 2.32. It is an integer overflow
leading to a SEGV in _bfd_dwarf2_find_nearest_line in dwarf2.c, as
demonstrated by nm (CVE-2019-17451).

GNU binutils gold linker is affected by Improper Input Validation, Signed/
Unsigned Comparison, Out-of-bounds Read. The impact is: Denial of service.
The attack vector is: An ELF file with an invalid e_shoff header field
must be opened (CVE-2019-1010204).
