Microsoft Releases Security Bulletin MS08-078

December 17th, 2008 . by DarkFiber Consulting

Microsoft has released Security Bulletin MS08-078 to address a vulnerability in Internet Explorer. This vulnerability is due to an invalid pointer reference in the data binding function. By convincing a user to view a specially crafted document that performs data binding (e.g., a web page, email message, or attachment), a remote, unauthenticated attacker may be able to execute arbitrary code.

DarkFiber Consulting encourages users to review Microsoft Security Bulletin MS08-078 and apply the update or workarounds listed in the bulletin to help mitigate the risks. Users may also want to consider implementing the best security practices listed in the Securing Your Web Browser document to strengthen their web browsers against future vulnerabilities.

Additional information regarding this vulnerability can be found in the Vulnerability Notes Database.

Multiple Web Browsers Affected by Clickjacking

September 26th, 2008 . by DarkFiber Consulting

DarkFiber Consulting is aware of public reports of a new cross-browser exploit technique called “Clickjacking.” According to one of the reports, Clickjacking gives an attacker the ability to trick a user into clicking on something only barely or momentarily noticeable. Therefore, if a user clicks on a web page, they may actually be clicking on content from another page. A separate report indicates that this flaw affects most web browsers and that no fix is available, but that disabling browser scripting and plug-ins may help mitigate some of the risks.

An additional report suggests that Firefox users consider using the NoScript plug-in as an added preventative measure. Disabling IFRAMEs by default, as outlined in the Securing Your Web Browser document, is reported to protect against the vulnerability.

DarkFiber Consulting encourages users to review the report and follow the security recommendations as described in the Securing Your Web Browser document to help mitigate some of the risks.

DarkFiber Consulting will provide additional information as it becomes available.
