The Lexmark Printer Software G2, G3 and G4 Installation Packages have a local escalation of privilege vulnerability due to a registry entry that has an unquoted service path.
Multiple buffer overflows in Lexmark MarkVision printer driver programs allows local users to gain privileges via long arguments to the cat_network, cat_paraller, and cat_serial commands.
The Lexmark Universal Print Driver version 2.15.1.0 and below, G2 driver 2.7.1.0 and below, G3 driver 3.2.0.0 and below, and G4 driver 4.2.1.0 and below are affected by a privilege escalation vulnerability. A standard low priviliged user can use the driver to execute a DLL of their choosing during the add printer process, resulting in escalation of privileges to SYSTEM.
