{"id":"AZL-34789","summary":"CVE-2022-28734 affecting package grub2 for versions less than 2.06-14","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":"2026-04-01T05:11:41.743494Z","published":"2023-07-20T01:15:10Z","upstream":["CVE-2022-28734"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-28734"}],"affected":[{"package":{"name":"grub2","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/grub2"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.06-14"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-34789.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"}]}
