CVE-2020-14310

There is an issue on grub2 before version 2.06 at function readsectionasstring. It expects a font name to be at max UINT32MAX - 1 length in bytes but it doesn't verify it before proceed with buffer allocation to read the value from the font value. An attacker may leverage that by crafting a...

Heap overflow

There is an issue on grub2 before version 2.06 at function readsectionasstring. It expects a font name to be at max UINT32MAX - 1 length in bytes but it doesn't verify it before proceed with buffer allocation to read the value from the font value. An attacker may leverage that by crafting a...

CVE-2020-14310

CVE-2020-14310 affects grub2 prior to version 2.06. The issue is in read_section_as_string(): a font name of length UINT32_MAX may trigger arithmetic overflow, causing zero-size allocation and a subsequent heap-based buffer overflow. This requires a crafted malicious font file and is a local impa...
