Vulnerability discussion

Data Execution Prevention (DEP) is a set of hardware and software technologies performing additional checks on memory to help prevent malicious code from running on a system. The primary benefit of DEP is to help prevent code execution from data pages. Enabling this setting, turns off Data Execution Prevention. As a result, malicious code takes advantage of code injection or buffer overflow vulnerabilities possibly exploiting the computer.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
