Secunia Advisory SA27552
Where:
Local system
Impact:
Privilege escalation,
Solution Status:
Vendor Patch
CVE Reference(s):
Description
A vulnerability has been reported in Microsoft Sysinternals DebugView, which can be exploited by malicious, local users to gain escalated privileges.
The problem is that the application loads the Dbgv.sys driver, which is accessible by all users and includes a certain unspecified function that can be exploited to e.g. copy arbitrary data to an arbitrary address.
Successful exploitation allows execution of arbitrary code with kernel privileges, but requires that the application is first started by a user with administrative privileges.
The vulnerability is reported in version 4.64. Other versions may also be affected.
Solution:
Update to version 4.72.
