Description


A vulnerability has been reported in Microsoft Windows, which can be exploited by malicious people to compromise a vulnerable system.

The vulnerability is caused due to an error in the License Logging service when processing arguments to the "LlsrLicenseRequestW" method. This can be exploited to cause a heap-based buffer overflow by sending an RPC packet containing a string that's not NULL terminated as expected.

Successful exploitation may allow execution of arbitrary code.
