descriptionThe remote Windows host contains a version of the Embedded OpenType (EOT) Font Engine that is affected by multiple buffer overflow vulnerabilities due to the way the EOT font technology parses name tables in specially crafted embedded fonts. If an attacker can trick a user on the affected system into viewing content rendered in a specially crafted EOT font, these issues could be leveraged to execute arbitrary code subject to the user
