Java Patch Plugs 19 Security Holes

Oracle this week released its quarterly patch update for Java, a widely-installed program that for most casual users has probably introduced more vulnerability than utility. If you have Java installed and require it for some application or Web site, it’s time to update it. If you’re not sure you have Java on your computer or are unsure why you still have it, read on for advice that could save you some security headaches down the road.

javamessOracle’s update brings Java 7 to Update 75 and Java 8 to Update 31, and fixes at least 19 security vulnerabilities in the program. Security vendor Qualys notes that 13 of those flaws are remotely exploitable, with a CVSS score of 10 (the most severe possible score).

Java 7 users should know that Oracle plans to start using the auto-update function built into the program to migrate those users to Java 8 this week.

According to a new report (PDF) from Cisco, online attacks that exploit Java vulnerabilities have decreased by 34 percent in the past year. Cisco reckons this is thanks to security improvements in the program, and to bad guys embracing new attack vectors — such Microsoft Silverlight flaws (if you’re a Netflix subscriber, you have Silverlight installed). Nevertheless, my message about Java will remain the same: Patch it, or pitch it. Continue reading →

Critical Updates for Windows, Adobe Flash, Air

Microsoft and Adobe each released patches today to plug critical security holes in their products. Microsoft issued seven update bundles to address at least 19 20 vulnerabilities in Windows and related software. Adobe released the fourth security update in nearly as many weeks for its Flash Player software, as well as a fix for Adobe AIR.

winiconMicrosoft today began pushing out seven security patches, four of them rated “critical,” meaning the flaws they fix could be used by malware or bad guys to break into unpatched systems with little or no help from users. The critical patches address bugs in Windows, Internet Explorer, Microsoft Silverlight, Microsoft Office and Microsoft SharePoint. Updates are available for Windows XP, Vista, Windows 7, Windows 8, Windows Server 2003, 2008 and 2012.

More information on the Microsoft patches is available at the Microsoft security response center blog, which also discusses some changes to the way security updates are applied to apps available through the Windows Store.

Critical Fixes from Microsoft, Adobe

If you use Microsoft Windows, it’s time again to get patched: Microsoft today issued nine updates to fix at least 21 security holes in its products. Separately, Adobe released a critical update that addresses nine vulnerabilities in its Shockwave Player software.

Four of the patches earned Microsoft’s most dire “critical” rating, meaning that miscreants and malware can leverage the flaws to hijack vulnerable systems remotely without any help from the user.  At least four of the vulnerabilities were publicly disclosed prior to the release of these patches.

The critical patches repair faulty components that can lead to browse-and-get-owned scenarios; among those is a fix for a vulnerability in Microsoft Silverlight, a browser plugin that is required by a number of popular sites — including Netflix — and can affect multiple browsers and even Mac systems. Microsoft believes that attackers are likely to quickly devise reliable exploits to attack at least a dozen of the 21 flaws it is fixing with this month’s release.
