HP signs malware with valid certificate

HP is revoking an old certificate from 2010 because its been used to sign a trojan horse. Investigation found that the problem origins from a HP developer's machine being infected.

The impact of this certificate revokation is small but can cause some problem for users with older HP systems trying to reinstall their drivers from 2010.

Cyanogenmod vulnerable to man-in-the-middle SSL attacks

The Cyanogenmod developers used example code from Oracles Java 1.5 certificate handling code and implemented in the project. It seems that this example code is vulnerable in the part that checks for hostnames.

Cyanogenmod is not the first developers that copy & pasted this flawed code from Oracle into their project.

Yet another SSL vulnerability with a fancy name, POODLE

The vulnerability is related to the design of SSL 3.0 and its somehow similar to the BEAST attack when it comes to impact and the fact that it would not be patched. The solution is to stop using SSL 3.0 which is nearly 18 years old.

Most modern browsers support newer versions than SSL 3.0 so there is no need to support it anymore. The only consideration is IE6 on Windows XP, which does not support might cause problem if you stop supporting SSL 3.0.

OS X Leaves Indexes With Private Data on USB Drives

F-Secure have discovered that your spotlight index can be saved to USB drives without you knowing about it. This is nothing new, but the problem is that the index might contain indexing of information that is not on your USB drive, but present somewhere else on your system. So if your mail is indexed it might be copied to an USB drive you plug in to your machine.

They have reproduced the issue and reported it to Apple which is "aware of the issue and investigates further".

There is no quickfix for this issue, but you can turn of spotlight indexing, or choose which folders it should index (i.e you can exclude your mail folder).

Remote execution vulnerability in Oracle Forms 10g

There is a critical vulnerability in Oracle Forms 10g which allows remote execution. An attacker can craft malicious parameters and add them to the URL to open a remote shell on the system.

Oracle Forms 10g is a discontinued product, and you should upgrade to version 11. If upgrade is not an option you should create a whitelist of allowed characters or removing support for JSP files on the remote web server.
