This can be exploited to cause a crash or potentially execute arbitrary code via specially crafted configured PAC files. - When processing GIF, color maps can be exploited to cause a heap based buffer overflow and potentially execute arbitrary code via a specially crafted GIF file. - An error in the 'XPCVariant::VariantDataToJS()' XPCOM utility, which can be exploited to execute arbitrary JavaScript code with chrome privileges. - An error in the implementation of the JavaScript 'document.getSelection()' can be exploited to read text selected on a web page in a different domain. - An error when downloading files can be exploited to display different file names in the download dialog title bar and download dialog body. This can be exploited to obfuscate file names via a right-to-left override character and potentially trick a user into running an executable file. - Multiple unspecified errors in the browser engines can be exploited to cause crash or potentially execute arbitrary code.

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
