Description

The remote host is running a version of the Windows kernel that is affected by the following vulnerabilities :

  • A NULL pointer deference that could allow privilege escalation. (CVE-2011-1985)

  • A DoS caused by processing a specially crafted TrueType font file. (CVE-2011-2002)

  • A code execution vulnerability triggered by tricking a user into opening a specially crafted .fon font file. (CVE-2011-2003)

  • A use after free vulnerability that could allow privilege escalation. (CVE-2011-2011)
