Java: Sizeable Critical Patch Update and Two Sugars, Please

Posted April 15, 2013    BeyondTrust Research Team

Oracle is rolling out yet another Critical Patch Update (CPU) for Java – and this time they’ve fixed 39 remotely exploitable vulnerabilities. This is not to say that all of these vulnerabilities may provide an attacker with remote code execution. However, the highest CVSS Base Score of all the vulnerabilities was a 10.0, meaning that an attacker would have gained a considerable amount of capabilities on the target machine if the vulnerability was properly exploited. The amount of vulnerabilities with a 10.0 CVSS score is not known, but if it is anything like February’s CPU, there may be a considerable amount.

This Critical Patch Update fixes a total of 42 security fixes, which is slightly outclassed by February’s CPU which brought 55 security updates, including the updated February re-release prompted by attacks occurring in the wild.

April’s CPU is coming out tomorrow, April 16th, with another CPU scheduled for June 18th, 2013. Oracle had promised in the past that they would be increasing the frequency of Java patches, so there is some likelihood of another unscheduled patch. As always, ensure that your systems that utilize Java are up-to-date using Retina CS, which also provides Java patching. If you have systems with Java installed that do not need Java, uninstall Java immediately and save yourself the headache.

Update: Java 7 Update 21 and Java 6 Update 45 have been released! For more information about the patch contents, check out Oracle’s risk matrix, which details the CVEs addressed in this latest patch. For more information about a few exploitable vulnerabilities that were patched in this update, read Adam Gowdiak’s (Security Explorations) description of some of the vulnerabilities they discovered and reported to Oracle. Also included in this update are a few changes to Java’s security prompts, which will prove useful for avoiding malicious Java applets that were self-signed or unsigned.

Passwords: A Hacker’s Best Friend

Posted September 1, 2015    Larry Brock

After all the years of talk about biometrics and multi-factor authentication, we still have passwords and will likely have them for a long time. Because many “high risk” systems require complex passwords (zk7&@1c6), most people that use them believe their passwords are secure. But they aren’t.

6 things I like about Gartner’s Cyber Resiliency Strategy

Posted August 27, 2015    Nigel Hedges

There were 6 key principles, or recommendations, that Gartner suggested were important drivers towards a great cyber resiliency posture. I commented more than once during the conference that many of these things were not new. They are all important recommendations that are best when placed together and given to senior management and the board – a critical element of organisations that desperately need to “get it”.
