Oracle has pushed a critical patch update for
its Java SE platform
that fixes at least 37 security vulnerabilities in the widely-installed
program. Several of these flaws are so severe that they are likely to be
exploited by malware or attackers in the days or weeks ahead. So — if you have
Java installed — it is time to update (or to ditch the program once and for
all).
The latest update for Java 7 (the version most users will
have installed) brings the program to Java 7 Update 55. Those who've chosen to upgrade to
the newer, “feature release” version of Java — Java 8 — will find fixes
available in Java 8 Update 5 (Java
8 doesn't work on Windows XP).
According to Oracle, at least four of the 37 security holes plugged in this release earned a Common Vulnerability Scoring
System(CVSS) rating of 10.0 — the most severe possible. According to Oracle,
vulnerabilities with a 10.0 CVSS score are those which can be easily exploited
remotely and without authentication, and which result in the complete compromise
of the host operating system.
If you really need and use Java for specific Web sites or
applications, take a few minutes to update this software. Updates are available
from Java.com or via the Java Control Panel. Keep
in mind that updating via the control panel will auto-select the installation
of the Ask Toolbar, so de-select that if you don’t want the added crapware.
Otherwise,
seriously consider removing Java altogether. End user have been advised not to make use of Java unless they have a specific use for it (this advice does not scale
for businesses, which often have legacy and custom applications that rely on
Java). This widely installed and powerful program is riddled with security
holes, and is a top target of malware writers and miscreants.
If you have an affirmative use or need for Java, unplug it
from the browser unless and until you’re at a site that requires it (or at
least take advantage of click-to-play). The
latest versions of Java let users disable Java content in web
browsers through the Java Control Panel.
Alternatively, consider a dual-browser approach, unplugging Java from the
browser you use for everyday surfing, and leaving it plugged in to a second
browser that you only use for sites that require Java.
