{"id":"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":"2026-07-30T08:13:22.994008Z","published":"2019-01-29T00:29:00.347Z","related":["SUSE-SU-2022:2614-1","SUSE-SU-2022:2614-2"],"references":[{"type":"REPORT","url":"https://sourceware.org/bugzilla/show_bug.cgi?id=24085"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://sourceware.org/git/elfutils.git","events":[{"introduced":"52b6b2f1f49e7385527e9f311f248092be0c0b61"},{"last_affected":"52b6b2f1f49e7385527e9f311f248092be0c0b61"}],"database_specific":{"cpe":"cpe:2.3:a:elfutils_project:elfutils:0.174:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0.174"},{"last_affected":"0.174"}],"source":"CPE_STRING"}}],"versions":["0.174","elfutils-0.174"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2019-7148.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H"}]}
