CVE-2012-6113 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-6113):
  The openssl_encrypt function in ext/openssl/openssl.c in PHP 5.3.9 through
  5.3.13 does not initialize a certain variable, which allows remote attackers
  to obtain sensitive information from process memory by providing zero bytes
  of input data.

These versions of php are no longer in the main tree.
