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...

The vulnerability of the Windows operating system’s font library allows a hacker to execute arbitrary code.

The vulnerability of the Windows operating system’s font library relates to the improper handling of embedded fonts. Exploiting this vulnerability allows a malicious actor to execute arbitrary code using a specially crafted font file from a remote location...

Microsoft Windows PFB Font File Out-Of-Bounds Write Privilege Escalation Vulnerability

This vulnerability allows local attackers to escalate privileges on affected installations of Microsoft Windows. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the parsing of...

grub2-bhyve -- multiple privilege escalations

Reno Robert reports: FreeBSD uses a two-process model for running a VM. For booting non-FreeBSD guests, a modified grub-emu is used grub-bhyve. Grub-bhyve executes command from guest grub.cfg file. This is a security problem because grub was never written to handle inputs from OS as untrusted. In...
