CVE-2022-28734 Description

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.
