Grub2 Heap Buffer Overflow DoS

The vulnerability of the readsectionasstring function in the Grub2 operating system’s loader is related to the issue of data operations going beyond the buffer boundaries. This is because the maximum length of a UINT32MAX is 1 byte. Exploiting this vulnerability could allow an attacker to influen...

grub2: Integer overflow read_section_as_string may lead to heap-based buffer overflow

A flaw was found in grub2. An expected font value is not verified before proceeding with buffer allocations allowing an attacker to use a malicious font file to create an arithmetic overflow, zero-sized allocation, and further heap-based buffer overflow. The highest threat from this vulnerability...
