grub2: Crafted PNG grayscale images may lead to out-of-bounds write in heap

A flaw was found in grub 2, where a crafted 16-bit grayscale PNG image may lead to an out-of-bounds write. This flaw allows an attacker to corrupt the data on the heap portion of the grub2's memory, leading to possible code execution and the circumvention of the secure boot mechanism...

grub2: Crafted JPEG image can lead to buffer underflow write in the heap

A flaw was found in grub2 when handling JPEG images. This flaw allows an attacker to craft a malicious JPEG image, which leads to an underflow on a grub2's internal pointer, leading to a heap-based out-of-bounds write. Secure-boot mechanisms circumvention and arbitrary code execution may also be...
