CVE-2018-18605
A specially crafted ELF allows remote attackers to cause a denial of service, as demonstrated by ld.
MEDIUM 5.5EPSS 2.32%
Does this matter?
Lower severity and a low EPSS score (2.32%). Track it; it rarely justifies an emergency change on its own.
Description
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.
