An issue was discovered in the merge_strings function in merge.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.31. There is a NULL pointer dereference in _bfd_add_merge_section when attempting to merge sections with large alignments. A specially crafted ELF allows remote attackers to cause a denial of service, as demonstrated by ld.

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.

binutils: NULL pointer dereference in _bfd_add_merge_section in merge_strings function in merge.c
An issue was discovered in the merge_strings function in merge.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.31. There is a NULL pointer dereference in _bfd_add_merge_section when attempting to merge sections with large alignments. A specially crafted ELF allows remote attackers to cause a denial of service, as demonstrated by ld.
Statement: This issue is classified with a low severity primarily because binutils is not typically exposed to untrusted inputs in most environments, limiting the possibility of exploitation. Additionally, this NULL pointer dereference is only triggered during the parsing of a specially crafted file, requiring an attac
