Secunia Advisory SA17595

Where:

From local network

Impact:

DoS

Solution Status:

Unpatched

CVE Reference(s):

No CVE references.

Description


Winny Thomas has discovered a vulnerability in Microsoft Windows, which can be exploited by malicious people to cause a DoS (Denial of Service).

The vulnerability is caused due to a memory allocation error when handling UPnP GetDeviceList requests via RPC. This can be exploited to cause "services.exe" to consume large amount of memory for a limited period of time.

Successful exploitation causes a DoS but requires valid logon credentials on Windows XP Service Pack 1.

The vulnerability has been confirmed in Windows 2000 SP4 and is also reported in Windows XP Service Pack 1.

Note: An exploit for this vulnerability is publicly available.


Solution:
Restrict access to the affected systems using a firewall.
