Mandriva Linux Security Advisory : php (MDVSA-2009:304)

This script is Copyright (C) 2009-2016 Tenable Network Security, Inc.


Synopsis :

The remote Mandriva Linux host is missing one or more security
updates.

Description :

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.

Solution :

Update the affected packages.

Risk factor :

High / CVSS Base Score : 7.5
(CVSS2#AV:N/AC:L/Au:N/C:P/I:P/A:P)
CVSS Temporal Score : 6.5
(CVSS2#E:ND/RL:OF/RC:C)
Public Exploit Available : true
