This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Novell iPrint Client. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The flaw exists within the nipplib component which is used by both the ActiveX and Netscape compatible browser plugins. When handling the driver-version parameter from the user specified printer-url the process blindly copies user supplied data into a fixed-length buffer on the heap. A remote attacker can exploit this vulnerability to execute arbitrary code under the context of the browser.
