For more information, see Microsoft Exploitability Index. A remote code execution vulnerability exists in the way that affected components handle a specially crafted OpenType font file.

The vulnerability could allow ms12-079 patch code execution if a user opens a specially crafted OpenType font file. An attacker who successfully exploited this vulnerability could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full administrative rights. Mitigation refers to a setting, common configuration, or general best-practice, existing in a default state, that could samsung apps whatsapp apk the severity of exploitation of a vulnerability.

The following mitigating factors may be helpful in your situation:. Workaround refers to a setting or configuration change that does not correct the underlying vulnerability but would help block known attack vectors before you ms12-079 patch the update. Microsoft has tested the following workarounds and states in the discussion whether a workaround reduces functionality.

Disable the WebClient service Disabling the WebClient service helps protect affected systems from attempts to exploit this vulnerability by blocking the most likely remote attack vector through the Web Distributed Authoring and Versioning WebDAV client service. After applying this workaround it is still ms12-079 patch for remote attackers who successfully exploit this vulnerability to cause the system to run programs located on the targeted user's computer or the Local Area Network LANbut users will be prompted for confirmation before opening arbitrary programs from the Internet.

Impact of workaround. In addition, any services that explicitly depend on the Web Client ms12-079 patch will not start, and an error message will be logged in ms12-079 patch System log.

For example, WebDAV shares will be inaccessible from the client computer. Block TCP ports and at the firewall These ports are used to initiate a connection ms12-079 patch the affected component. Blocking TCP ports and at the firewall will help protect systems that are behind that firewall from attempts to exploit this vulnerability. Microsoft recommends that you block all unsolicited inbound communication from the Internet to help prevent attacks that may use other ports.

Several Windows services use the affected ms12-079 patch. Blocking connectivity to the ports may cause various applications or services to not function. Some of the applications or services that could be impacted are listed below:. How to undo the workaround. Ms12-079 patch TCP ports and at the firewall.
