A heap-based buffer over-read issue was discovered in the function sec_merge_hash_lookup in merge.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.31, because _bfd_add_merge_section mishandles section merges when size is not a multiple of entsize. 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: heap-based buffer over-read in sec_merge_hash_lookup in merge.c
A heap-based buffer over-read issue was discovered in the function sec_merge_hash_lookup in merge.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.31, because _bfd_add_merge_section mishandles section merges when size is not a multiple of entsize. 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 heap-based buffer over-read is only triggered during the parsing of a specially crafted file, requiring an attacker to c
