Some vulnerabilities were discovered and corrected in php:
PHP 5.2.11, and 5.3.x before 5.3.1, does not restrict the number
of temporary files created when handling a multipart/form-data POST
request, which allows remote attackers to cause a denial of service
(resource exhaustion), and makes it easier for remote attackers to
exploit local file inclusion vulnerabilities, via multiple requests,
related to lack of support for the max_file_uploads directive
(CVE-2009-4017).
The proc_open function in ext/standard/proc_open.c in PHP
before 5.2.11 and 5.3.x before 5.3.1 does not enforce the (1)
safe_mode_allowed_env_vars and (2) safe_mode_protected_env_vars
directives, which allows context-dependent attackers to execute
programs with an arbitrary environment via the env parameter, as
demonstrated by a crafted value of the LD_LIBRARY_PATH environment
variable (CVE-2009-4018).
The updated packages have been patched to correct these issues.
