Security update for php5 (important)

php5 was updated to fix four security issues.

These security issues were fixed:

• CVE-2015-0231: Use-after-free vulnerability in the process_nested_data
  function in ext/standard/var_unserializer.re in PHP before 5.4.37, 5.5.x
  before 5.5.21, and 5.6.x before 5.6.5 allowed remote attackers to
  execute arbitrary code via a crafted unserialize call that leverages
  improper handling of duplicate numerical keys within the serialized
  properties of an object. NOTE: this vulnerability exists because of an
  incomplete fix for CVE-2014-8142 (bnc#910659).
• CVE-2014-9427: sapi/cgi/cgi_main.c in the CGI component in PHP through
  5.4.36, 5.5.x through 5.5.20, and 5.6.x through 5.6.4, when mmap is used
  to read a .php file, did not properly consider the mapping’s length
  during processing of an invalid file that begins with a # character and
  lacks a newline character, which caused an out-of-bounds read and might
  (1) allow remote attackers to obtain sensitive information from php-cgi
  process memory by leveraging the ability to upload a .php file or (2)
  trigger unexpected code execution if a valid PHP script is present in
  memory locations adjacent to the mapping (bnc#911664).
• CVE-2015-0232: The exif_process_unicode function in ext/exif/exif.c in
  PHP before 5.4.37, 5.5.x before 5.5.21, and 5.6.x before 5.6.5 allowed
  remote attackers to execute arbitrary code or cause a denial of service
  (uninitialized pointer free and application crash) via crafted EXIF data
  in a JPEG image (bnc#914690).
• CVE-2014-8142: Use-after-free vulnerability in the process_nested_data
  function in ext/standard/var_unserializer.re in PHP before 5.4.36, 5.5.x
  before 5.5.20, and 5.6.x before 5.6.4 allowed remote attackers to
  execute arbitrary code via a crafted unserialize call that leverages
  improper handling of duplicate keys within the serialized properties of
  an object, a different vulnerability than CVE-2004-1019 (bnc#910659).

Additionally a fix was included that protects against a possible NULL
pointer use (bnc#910659).

This non-security issue was fixed:

• php53 ignored default_socket_timeout on outgoing SSL connection
  (bnc#907519).
