Daylight Saving Time Changes for 2007added March 5, 2007The start and end dates for Daylight Saving Time (DST) will change this year in accordance with the Energy Policy Act of 2005. With the new rules, clocks will be set ahead on March 11th instead of April 1st, and will be turned back on November 4th instead of October 28th. The change will have an effect on and require updates to many computing systems that are time reliant. For example, any organization using software to perform scheduling, billing, transaction logging, and other time-related calculations could be at risk if upgrades are not performed. All organizations should prepare for the DST changeover by analyzing their systems and applying the appropriate updates. While the level of effort will vary widely across systems, platforms, and industries, every computing environment should be assessed for potential impact, as it is likely that most systems will require some pre-changeover action.

Exploit Code Posted for XSS Vulnerability in Google Desktop Search Engineadded February 22, 2007 | updated February 23, 2007US-CERT is aware of publicly available exploit code for a cross-site (XSS) scripting vulnerability in the Google Desktop Search engine. The vulnerability exists due to a flaw in the way the Google Desktop Search engine processes malformed user input. By persuading a user to view a specially crafted HTML document (e.g., a web page or an HTML email message), a remote unauthenticated attacker may be able to execute existing arbitrary code, search and view files, or steal sensitive data. Note: Without the presence of another vulnerability, remote exploitation is not possible. Google has addressed this issue in the latest version of Google Desktop, which updates automatically. More information about this vulnerability is located in the following:
US-CERT recommends the following workaround to help mitigate the security risks:
Vulnerability in JBOSS Application Serveradded February 20, 2007 | updated February 22, 2007US-CERT is aware of a vulnerability in JBoss Application Server. If the JBoss Application Server is installed without using the advanced installer, and these steps are not taken to secure the server, a vulnerable condition may occur. If a JBoss Application Server is improperly configured to allow unauthenticated access to the administrative interface, and is accessible from a network, then an unauthenticated, remote attacker may be able to gain access to, and possibly modify, data on the server. Note: Using the advanced installer options will configure JBoss to allow only authenticated administrative access by default. More information about this vulnerability is located in the following:

Symantec Warns Users of New Drive-By Pharming Attackadded February 16, 2007In an announcement made yesterday, security researchers at Symantec and Indiana University School of Informatics revealed that they had uncovered a serious new security threat targeting home broadband routers. The attack, dubbed Drive-By Pharming, allows an attacker to change the configuration of a home router when a user unknowingly visits a malicious website. The website employs malicious JavaScript code that allows an attacker to log into many types of home routers if the default password has not been changed. Once logged in, the attacker is able to change the configuration of the home router, including the Domain Name Server (DNS) server settings. This type of attack is particularly concerning for a few reasons:
Symantec notes that the best defense against this type of attack is for home users to change their default password. The following links provide support resources for three of the more common home router vendors: US-CERT cautions users to avoid clicking on links sent in unsolicited emails. Users should also remain cautious when browsing the web and avoid visiting untrusted sites. More information can be found in Securing Your Web Browser document.
