It has been few days that some rumors were talking about a new SSLv3 vulnerability. It’s been confirmed yesterday by the Google Security team as they released the details of the vulnerability. See CVE-2014-3566.

The SSL protocol 3.0, as used in OpenSSL through 1.0.1i and other products, uses nondeterministic CBC padding, which makes it easier for man-in-the-middle attackers to obtain cleartext data via a padding-oracle attack, aka the “POODLE” issue.

You must disable SSLv3.0 or CBC-mode ciphers with SSLv3.0 to mitigate the issue. You should make sure to do this for all your services, including third party services like Amazon AWS CloudFront.


A Bash vulnerability has just been announced, rated 10 on a scale of 10. The vulnerability is Network Exploitable. Patch Now.

GNU Bash through 4.3 incorrectly handle trailing strings after function definitions in the values of environment variables. An attacker could use this issue to bypass environment restrictions, such as SSH forced command environments, and execute arbitrary code.

You need to patch your systems now.

Update: If you already patched your system. Check it again. You may have to patch again due to a previous incomplete fixes. See CVE-2014-7169, Incomplete fix for CVE-2014-6271

  • Constant scalar expressions.
  • Variadic functions and argument unpacking using the … operator.
  • Exponentiation using the ** operator.
  • Function and constant importing with the use keyword.
  • phpdbg as an interactive integrated debugger SAPI.
  • php://input is now reusable, and $HTTP_RAW_POST_DATA is deprecated.
  • GMP objects now support operator overloading.
  • File uploads larger than 2 gigabytes in size are now accepted.

You can find the complete features list on the PHP Website.

One of the new features is the integrated phpdbg debugger which provides an interactive environment to debug your PHP code. phpdbg is implemented and distributed as an SAPI module. The phpdbg website has some good documentation, I recommend the Getting started with phpdbg section. This is not a replacement for XDebug.

Let’s cover how to get started with PHP 5.6.0 and phpdbg on Mac OS X.
