A vulnerability in the boot logic of Cisco IOS XE Software could allow an authenticated, local attacker with level 15 privileges or an unauthenticated attacker with physical access to execute arbitrary code on the underlying Linux operating system of an affected device. This vulnerability is due to incorrect validations of specific function arguments that are passed to the boot script. An attacker could exploit this vulnerability by tampering with a specific file, which an affected device would process during the initial boot process. On systems that are protected by the Unified Extensible Firmware Interface (UEFI) secure boot feature, a successful exploit could allow the attacker to execute unsigned code at boot time and bypass the image verification check in the secure boot process of the affected device.

## Vulnerability Spotlight: Use-after-free in Google Chrome could lead to code execution
Marcin Towalski of Cisco Talos discovered this vulnerability.
Cisco Talos recently discovered an exploitable use-after-free vulnerability in Google Chrome.
Google Chrome is a cross-platform web browser — and Chromium is the open-source version of the browser that other software developers use to build their browsers, as well. This specific vulnerability exists in a specific object in the browser that's responsible for creating streams of audio and video.
