{"id":"CVE-2022-28737","details":"There's a possible overflow in handle_image() when shim tries to load and execute crafted EFI executables; The handle_image() function takes into account the SizeOfRawData field from each section to be loaded. An attacker can leverage this to perform out-of-bound writes into memory. Arbitrary code execution is not discarded in such scenario.","modified":"2026-04-10T04:47:02.957565Z","published":"2023-07-20T01:15:10.473Z","related":["ALSA-2022:5095","ALSA-2022:5099","SUSE-SU-2023:1702-1","SUSE-SU-2023:1863-1","SUSE-SU-2023:2084-1","SUSE-SU-2023:2086-1","SUSE-SU-2023:2091-1","SUSE-SU-2023:2150-1","SUSE-SU-2024:1368-1","SUSE-SU-2024:1461-1","SUSE-SU-2024:1462-1"],"references":[{"type":"ADVISORY","url":"https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-28737"},{"type":"ADVISORY","url":"https://www.openwall.com/lists/oss-security/2022/06/07/5"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/rhboot/shim","events":[{"introduced":"0"},{"fixed":"505cdb678b319fcf9a7fdee77c0f091b4147cbe5"}],"database_specific":{"versions":[{"introduced":"0"},{"fixed":"15.6"}]}}],"versions":["0.3","0.4","0.5","0.7","0.8","0.9","11","12","13","14","15","15.2","15.3","15.4","15.5","15.5-rc2","15.6-rc2","shim-15.3-rc1","shim-15.3-rc2","shim-15.3-rc3","shim-15.3-rc4"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-28737.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"}]}
