Discourse vulnerable to auto-executing of third-party code in embedded CodePen iframe

Discourse is an open-source discussion platform. Prior to version 3.4.4 of the `stable` branch, version 3.5.0.beta5 of the `beta` branch, and version 3.5.0.beta6-dev of the `tests-passed` branch, Codepen is present in the default `allowed_iframes` site setting, and it can potentially auto-run arbitrary JS in the iframe scope, which is unintended. This issue is patched in version 3.4.4 of the `stable` branch, version 3.5.0.beta5 of the `beta` branch, and version 3.5.0.beta6-dev of the `tests-passed` branch. As a workaround, the Codepen prefix can be removed from a site's `allowed_iframes`.

Dell BIOS versions contain an Insecure Automated Optimization vulnerability. A local authenticated malicious user could exploit this vulnerability by sending malicious input via SMI to obtain arbitrary code execution during SMM.

Dell BIOS versions contain an Unchecked Return Value vulnerability. A local authenticated administrator user could potentially exploit this vulnerability in order to change the state of the system or cause unexpected failures.
