DESCRIPTION:
Peter Winter-Smith of NGSSoftware has reported a vulnerability in the
LexBce Server Service included with various Lexmark printers, which
can be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to an unspecified error in the
printer sharing service provided by the LexBce Server Service
(LexPPS.EXE). This can be exploited to execute arbitrary code on a
system with Lexmark printer installed.

NOTE: The service is installed with the printer drivers of Lexmark
X1100 series (LexPPS version 8.29), and X2200 series (LexPPS version
9.41). Other Lexmark printers may also have the service installed.

SOLUTION:
Disable the service if printer sharing is not required.

PROVIDED AND/OR DISCOVERED BY:
Peter Winter-Smith, NGSSoftware.
