Polish security firm Security Explorations has sent an advisory, with a proof-of-concept exploit, to Oracle today (Friday 31 AUG) specific to a vulnerability they discovered in the Java 7 security update released Thursday.  This newly reported vulnerability can be exploited to escape the Java sandbox and execute arbitrary code on the underlying system.
Standby for more on this one, no word yet from Oracle regarding their remediation plans.

As Rapid7's Tod Beardsley has said: "As it happens, very few websites rely on Java for dynamic content. Java isn't relied on nearly as much as Javascript and Flash. Most people can disable their Java browser plugin and not really notice the difference."

What mitigations are you utilizing to protect yourselves? Going so far as disabling Java all together? Feedback welcome via comments.

See Scott's post from yesterday for the original advisory details.

VMware released one new security advisory, and updated 2 older once.

New: VMSA-2012-0013 [1]

The update affects vCenter (and Update Manager) 4.1 without Update 3, as well as ESX/ESXi. It patches a number of open source components that are included as part of VMware: Apache struts, popt/rpm, glibc, libxm2, Perl, OpenSSL, JRE and the Linux Kernel.

An interesting update is the update of Java, which is included in ESX. Some of the older versions of ESX and vCenter still use Java 1.5, which was left out of the recent issues. However, for those VMware products that do use Java 1.6, only update 31 is provided. As of yesterday, Update 35 is "current". 


VMSA-2012-0005.2 [2]:  Added Windows 7 information
VMSA-2012-0012.1 [3]: included information about vSphere 4.1 U3
