CVE-2018-20651 (opens in a new tab)Amendment
The SLES security team deemed this advisory irrelevant for SLES:15.0.
NVD Description
Note: Versions mentioned in the description apply only to the upstream cross-hppa-binutils package and not the cross-hppa-binutils package as distributed by SLES.
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.
