An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.31. An invalid memory address dereference was discovered in read_reloc in reloc.c. The vulnerability causes a segmentation fault and application crash, which leads to denial of service, as demonstrated by objdump, because of missing _bfd_clear_contents bounds checking.

CVE-2018-19932 GNU binutils vulnerabilities
Title: GNU binutils vulnerabilities
Summary: Several security issues were fixed in GNU binutils.
USN-4336-1 fixed several vulnerabilities in GNU binutils. This update provides
the corresponding update for Ubuntu 16.04 ESM.
Original advisory details:
It was discovered that GNU binutils contained a large number of security
issues. If a user or automated system were tricked into processing a
specially-crafted file, a remote attacker could cause GNU binutils to
crash, resulting in a denial of service, or possibly execute arbitrary
code.
Instructions: In general, a standard system update will make all the necessary changes.

CVE-2018-18309 [MEDIUM] CWE-119 binutils: invalid memory address dereference in read_reloc in reloc.c
binutils: invalid memory address dereference in read_reloc in reloc.c
An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.31. An invalid memory address dereference was discovered in read_reloc in reloc.c. The vulnerability causes a segmentation fault and application crash, which leads to denial of service, as demonstrated by objdump, because of missing _bfd_clear_contents bounds checking.
Statement: Red Hat has determined this flaw to be of low impact as successful exploitation results in a crash (denial of service) of the application utilizing the binutils library and does not impact system-wide stability or lead to arbitrary code execution or memory corruption.
