CVE-2022-28734

Status Candidate

Overview

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.

Ubuntu Security Notice 6355-1 - Daniel Axtens discovered that specially crafted images could cause a heap-based out-of-bonds write. A local attacker could possibly use this to circumvent secure boot protections. Daniel Axtens discovered that specially crafted images could cause out-of-bonds read and write. A local attacker could possibly use this to circumvent secure boot protections. Daniel Axtens discovered that specially crafted images could cause buffer underwrite which allows arbitrary data to be written to a heap. A local attacker could possibly use this to circumvent secure boot protections.
