VULNERABILITY DETAILS


This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Novell iPrint Client. User interaction is required in that a target must visit a malicious page or open a malicious file.

The flaw exists within the exposed GetDriverSettings method in the nipplib component imported by ienipp and npnipp. When encountering a realm parameter this user supplied value's length is not properly verified before copying into a fixed length buffer on the stack. A remote attacker can exploit this vulnerability to execute arbitrary code under the context of the process.
