Microsoft Windows kernel font code execution
| win-kernel-font-code-execution (53974) |  High Risk |
Description:
Microsoft Windows kernel-mode drivers could allow a remote attacker to execute arbitrary code on the system, caused by the improper parsing of font code when building a table of directory entries. By persuading a victim to open a specially-crafted file containing EOT font embedded in the document, a remote attacker could execute arbitrary code on the system or cause the application to crash.
