Vulnerability Details

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

The specific flaw exists within handling plugin parameters. The application does not properly verify the name of parameters passed via <embed> tags. If a malicious attacker provides a long enough value a destination buffer can be overflowed. Successful exploitation leads to execution of arbitrary code under the context of the user owning the browser process.

Novell has issued an update to correct this vulnerability. More details can be found at:
