New tool? Tell us	Local root compromise through Lexmark MarkVision printer drivers 9 Dec. 2000    Summary MarkVision is a printer administration package from Lexmark. In addition to software to remotely administer printers, it also provides printer drivers for a wide variety of printers for various flavors of Unix. Several of the utilities that make up the Unix printer drivers contain command line buffer overflows. As some of these utilities are installed setuid root, a local attacker can trivially exploit the vulnerabilities to execute arbitrary code as root.   Credit: The information has been provided by Secure Reality Advisories.    Details Audit your web server for security holes - see what the hackers see.
