{"id":"ALPINE-CVE-2019-7148","details":"An attempted excessive memory allocation was discovered in the function read_long_names in elf_begin.c in libelf in elfutils 0.174. Remote attackers could leverage this vulnerability to cause a denial-of-service via crafted elf input, which leads to an out-of-memory exception. NOTE: The maintainers believe this is not a real issue, but instead a \"warning caused by ASAN because the allocation is big. By setting ASAN_OPTIONS=allocator_may_return_null=1 and running the reproducer, nothing happens.\"","modified":"2026-09-10T06:17:54.565423479Z","published":"2019-01-29T00:29:00.347Z","upstream":["CVE-2019-7148"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2019-7148"}],"affected":[{"package":{"name":"elfutils","ecosystem":"Alpine:v3.12","purl":"pkg:apk/alpine/elfutils?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.176-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-7148.json"}},{"package":{"name":"elfutils","ecosystem":"Alpine:v3.13","purl":"pkg:apk/alpine/elfutils?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.176-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-7148.json"}},{"package":{"name":"elfutils","ecosystem":"Alpine:v3.14","purl":"pkg:apk/alpine/elfutils?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.176-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-7148.json"}},{"package":{"name":"elfutils","ecosystem":"Alpine:v3.15","purl":"pkg:apk/alpine/elfutils?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.176-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-7148.json"}},{"package":{"name":"elfutils","ecosystem":"Alpine:v3.16","purl":"pkg:apk/alpine/elfutils?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.176-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-7148.json"}},{"package":{"name":"elfutils","ecosystem":"Alpine:v3.17","purl":"pkg:apk/alpine/elfutils?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.176-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-7148.json"}},{"package":{"name":"elfutils","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/elfutils?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.176-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-7148.json"}},{"package":{"name":"elfutils","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/elfutils?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.176-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-7148.json"}},{"package":{"name":"elfutils","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/elfutils?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.176-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-7148.json"}},{"package":{"name":"elfutils","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/elfutils?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.176-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-7148.json"}},{"package":{"name":"elfutils","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/elfutils?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.176-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-7148.json"}},{"package":{"name":"elfutils","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/elfutils?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.176-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-7148.json"}},{"package":{"name":"elfutils","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/elfutils?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.176-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-7148.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H"}]}
