Title: Microsoft Windows Embedded OpenType Font Engine Remote Code Execution Vulnerability
Severity: CRITICAL
Description:
Embedded OpenType (EOT) fonts are designed for use on webpages. EOT fonts can also be embedded in documents.
Microsoft Windows is prone to a remote code-execution vulnerability that may affect 'OS\2' table records in Embedded OpenType fonts. Specifically, an integer-wrap issue occurs when adding a directory entry's offset and its size member.
To exploit this issue, an attacker may entice an unsuspecting user into visiting a malicious webpage.
Successful exploits will allow the attacker to execute arbitrary code with kernel-level privileges and completely compromise the affected computer.
