CVE-2014-8142 (http://nvd.nist.gov/nvd.cfm?cvename=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 allows 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.

[Comment 15 Yury German 2014-12-29 01:50:34 UTC]

Arches, Thank you for your work
Maintainer(s), please drop the vulnerable version(s).

New GLSA Request filed.

[Comment 16 GLSAMaker/CVETool Bot 2015-01-11 21:02:52 UTC]

CVE-2014-9427 (http://nvd.nist.gov/nvd.cfm?cvename=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, does not properly consider the mapping's length during processing of
  an invalid file that begins with a # character and lacks a newline
  character, which causes 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.

[Comment 17 Yury German 2015-02-01 02:25:18 UTC]

Maintainer(s), it has been 30 days since request for cleanup. 
Please drop the vulnerable versions.

[Comment 18 Sergey Popov (RETIRED) 2015-03-07 09:25:55 UTC]

Cleanup would be done in bug #533998
