CVE-2018-20651 (opens in a new tab)How to fix?
Upgrade SLES:15.1 binutils-gold to version 2.32-7.5.1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream binutils-gold package and not the binutils-gold package as distributed by SLES.
See How to fix? for SLES:15.1 relevant fixed versions and status.
A NULL pointer dereference was discovered in elf_link_add_object_symbols in elflink.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.31.1. This occurs for a crafted ET_DYN with no program headers. A specially crafted ELF file allows remote attackers to cause a denial of service, as demonstrated by ld.
