{"id":"CVE-2022-28734","details":"Out-of-bounds write when handling split HTTP headers; When handling split HTTP headers, GRUB2 HTTP code accidentally moves its internal data buffer point by one position. This can lead to a out-of-bound write further when parsing the HTTP request, writing a NULL byte past the buffer. It's conceivable that an attacker controlled set of packets can lead to corruption of the GRUB2's internal memory metadata.","modified":"2026-03-15T22:45:03.170347Z","published":"2023-07-20T01:15:10.243Z","related":["ALSA-2022:5095","ALSA-2022:5099","SUSE-SU-2022:2035-1","SUSE-SU-2022:2036-1","SUSE-SU-2022:2037-1","SUSE-SU-2022:2038-1","SUSE-SU-2022:2039-1","SUSE-SU-2022:2041-1","SUSE-SU-2022:2064-1","SUSE-SU-2022:2073-1","SUSE-SU-2022:2074-1","openSUSE-SU-2024:12137-1"],"references":[{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20230825-0002/"},{"type":"ADVISORY","url":"https://www.openwall.com/lists/oss-security/2022/06/07/5"},{"type":"ADVISORY","url":"https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-28734"}],"affected":[{"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"2.00"},{"fixed":"2.06-3"}]}],"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-28734.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:H"}]}
