"PHP has been cited with the following multiple vulnerabilities, which
may be locally exploitable on some F5 products :

CVE-2006-7243 PHP before 5.3.4 accepts the \0 character in a pathname,
which might allow context-dependent attackers to bypass intended
access restrictions by placing a safe file extension after this
character, as demonstrated by .php\0.jpg at the end of the argument to
the file_exists function.

CVE-2007-3799 The session_start function in ext/session in PHP 4.x up
to 4.4.7 and 5.x up to 5.2.3 allows remote attackers to insert
arbitrary attributes into the session cookie via special characters in
a cookie that is obtained from (1) PATH_INFO, (2) the session_id
function, and (3) the session_start function, which are not encoded or
filtered when the new session cookie is generated, a related issue to
CVE-2006-0207.

CVE-2010-3710 Stack consumption vulnerability in the filter_var
function in PHP 5.2.x through 5.2.14 and 5.3.x through 5.3.3, when
FILTER_VALIDATE_EMAIL mode is used, allows remote attackers to cause a
denial of service (memory consumption and application crash) via a
long e-mail address string.

CVE-2010-3870 The utf8_decode function in PHP before 5.3.4 does not
properly handle non-shortest form UTF-8 encoding and ill-formed
subsequences in UTF-8 data, which makes it easier for remote attackers
to bypass cross-site scripting (XSS) and SQL injection protection
mechanisms via a crafted string.

CVE-2010-4697 Use-after-free vulnerability in the Zend engine in PHP
before 5.2.15 and 5.3.x before 5.3.4 might allow context-dependent
attackers to cause a denial of service (heap memory corruption) or
have unspecified other impact via vectors related to use of __set,
__get, __isset, and __unset methods on objects accessed by a
reference.

CVE-2011-1470 The Zip extension in PHP before 5.3.6 allows
context-dependent attackers to cause a denial of service (application
crash) via a ziparchive stream that is not properly handled by the
stream_get_contents function.

CVE-2011-3182 PHP before 5.3.7 does not properly check the return
values of the malloc, calloc, and realloc library functions, which
allows context-dependent attackers to cause a denial of service (NULL
pointer dereference and application crash) or trigger a buffer
overflow by leveraging the ability to provide an arbitrary value for a
function argument, related to (1) ext/curl/interface.c, (2)
ext/date/lib/parse_date.c, (3) ext/date/lib/parse_iso_intervals.c, (4)
ext/date/lib/parse_tz.c, (5) ext/date/lib/timelib.c, (6)
ext/pdo_odbc/pdo_odbc.c, (7) ext/reflection/php_reflection.c, (8)
ext/soap/php_sdl.c, (9) ext/xmlrpc/libxmlrpc/base64.c, (10)
TSRM/tsrm_win32.c, and (11) the strtotime function.

CVE-2011-3267 PHP before 5.3.7 does not properly implement the
error_log function, which allows context-dependent attackers to cause
a denial of service (application crash) via unspecified vectors.

CVE-2011-3268 Buffer overflow in the crypt function in PHP before
5.3.7 allows context-dependent attackers to have an unspecified impact
via a long salt argument, a different vulnerability than
CVE-2011-2483.

CVE-2011-4566 Integer overflow in the exif_process_IFD_TAG function in
exif.c in the exif extension in PHP 5.4.0beta2 on 32-bit platforms
allows remote attackers to read the contents of arbitrary memory
locations or cause a denial of service via a crafted offset_val value
in an EXIF header in a JPEG file, a different vulnerability than
CVE-2011-0708.

CVE-2012-0830 The php_register_variable_ex function in php_variables.c
in PHP 5.3.9 allows remote attackers to execute arbitrary code via a
request containing a large number of variables, related to improper
handling of array variables. NOTE: this vulnerability exists because
of an incorrect fix for CVE-2011-4885."
