{"id":"CVE-2018-20651","details":"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.","modified":"2026-04-10T04:10:04.310011Z","published":"2019-01-01T16:29:00.343Z","related":["SUSE-SU-2019:2650-1","SUSE-SU-2019:2779-1","SUSE-SU-2019:2780-1","openSUSE-SU-2019:2415-1","openSUSE-SU-2019:2432-1","openSUSE-SU-2024:10651-1"],"references":[{"type":"WEB","url":"https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git%3Bh=54025d5812ff100f5f0654eb7e1ffd50f2e37f5f"},{"type":"WEB","url":"https://usn.ubuntu.com/4336-1/"},{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00072.html"},{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00008.html"},{"type":"ADVISORY","url":"http://www.securityfocus.com/bid/106440"},{"type":"ADVISORY","url":"https://security.gentoo.org/glsa/201908-01"},{"type":"ADVISORY","url":"https://support.f5.com/csp/article/K38336243"},{"type":"REPORT","url":"https://sourceware.org/bugzilla/show_bug.cgi?id=24041"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://sourceware.org/git/binutils-gdb.git","events":[{"introduced":"0"},{"last_affected":"0860693812fff944ab0602e72b762a4a2078da5b"}],"database_specific":{"versions":[{"introduced":"0"},{"last_affected":"2.31.1"}]}}],"versions":["binutils-2_31","binutils-2_31_1","gdb-4_18-branchpoint","gdb-7.10-branchpoint","gdb-7.11-branchpoint","gdb-7.12-branchpoint","gdb-7.7-branchpoint","gdb-7.8-branchpoint","gdb-7.9-branchpoint","gdb-8.0-branchpoint","gdb-8.1-branchpoint","gdb_5_2-branchpoint","gdb_5_3-branchpoint","gdb_6_0-branchpoint","gdb_6_1-branchpoint","gdb_6_2-branchpoint","gdb_6_3-branchpoint","gdb_6_4-branchpoint","gdb_6_5-branchpoint","gdb_6_6-branchpoint","gdb_6_7-branchpoint","gdb_6_8-branchpoint","gdb_7_0-branchpoint","gdb_7_1-branchpoint","gdb_7_2-branchpoint","gdb_7_3-branchpoint","gdb_7_4-branchpoint","gdb_7_5-branchpoint","gdb_7_6-branchpoint","users/ARM/embedded-binutils-master-2016q4","users/ARM/embedded-binutils-master-2017q4","users/ARM/embedded-gdb-master-2017q4"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2018-20651.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H"}]}
