Description

The remote Windows host is affected by multiple vulnerabilities :

  • Multiple privilege escalation vulnerabilities exist in the Windows kernel-mode driver due to improper handling of objects in memory. A local attacker can exploit these vulnerabilities, with a specially crafted application, to elevate privileges to full administrative rights. (CVE-2015-2363, CVE-2015-2365, CVE-2015-2366)

  • An information disclosure vulnerability exists in the Windows kernel-mode driver due to improper handling of non-initialized values in memory. An attacker can exploit this vulnerability, with a specially crafted application, to leak memory addresses or other sensitive kernel information that can be used for further exploitation of the system. (CVE-2015-2367)

  • An information disclosure vulnerability exists in the Windows kernel-mode driver due to improper handling of private address information during a function call. An attacker can exploit this vulnerability, with a specially crafted application, to request the contents of specific memory addresses. (CVE-2015-2381, CVE-2015-2382)
