{"id":"CVE-2018-18309","details":"An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.31. An invalid memory address dereference was discovered in read_reloc in reloc.c. The vulnerability causes a segmentation fault and application crash, which leads to denial of service, as demonstrated by objdump, because of missing _bfd_clear_contents bounds checking.","modified":"2026-05-18T15:06:57.516849Z","published":"2018-10-15T02:29:00.767Z","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":"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":"WEB","url":"https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git%3Bh=0930cb3021b8078b34cf216e79eb8608d017864f"},{"type":"WEB","url":"https://usn.ubuntu.com/4336-1/"},{"type":"ADVISORY","url":"http://www.securityfocus.com/bid/105692"},{"type":"FIX","url":"https://sourceware.org/bugzilla/show_bug.cgi?id=23770"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://sourceware.org/git/binutils-gdb.git","events":[{"introduced":"0"},{"last_affected":"af127c216949509e57ab2a28cc56c44e4e548813"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"last_affected":"2.31"}],"cpe":"cpe:2.3:a:gnu:binutils:2.31:*:*:*:*:*:*:*","source":"CPE_FIELD"}}],"versions":["binutils-2_31","gdb-8.1-branchpoint","users/ARM/embedded-gdb-master-2017q4","users/ARM/embedded-binutils-master-2017q4","gdb-8.0-branchpoint","users/ARM/embedded-binutils-master-2016q4","gdb-7.12-branchpoint","gdb-7.11-branchpoint","gdb-7.10-branchpoint","gdb-7.9-branchpoint","gdb-7.8-branchpoint","gdb-7.7-branchpoint","gdb_7_6-branchpoint","gdb_7_5-branchpoint","gdb_7_4-branchpoint","gdb_7_3-branchpoint","gdb_7_2-branchpoint","gdb_7_1-branchpoint","gdb_7_0-branchpoint","gdb_6_8-branchpoint","gdb_6_7-branchpoint","gdb_6_6-branchpoint","gdb_6_5-branchpoint","gdb_6_4-branchpoint","gdb_6_3-branchpoint","gdb_6_2-branchpoint","gdb_6_1-branchpoint","gdb_6_0-branchpoint","gdb_5_3-branchpoint","gdb_5_2-branchpoint","gdb-4_18-branchpoint"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2018-18309.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"}]}
