Aviv Raff has discovered a vulnerability in Internet Explorer, which can be exploited by malicious people to compromise a user's system.
Input passed via links within an HTML file is not being properly sanitised before being used to generate a printable HTML file. This can be exploited to inject arbitrary script code, which is executed in local context when a user is enticed to print a specially crafted HTML document with the "Print table of links" option enabled.
Successful exploitation allows execution of arbitrary code.
The vulnerability is confirmed in Internet Explorer 6 and 7 on a fully patched Windows XP SP2. Other versions may also be affected.
Solution: Do not print HTML files from untrusted sources with the "Print table of links" option.
