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.

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.

Insufficient handling of certain character sequences in the utf8_decode() function could be leveraged to conduct cross-site-scripting (XSS) attacks (CVE-2010-3870). php5 could also consume large amounts of memory and crash if a long mail address was passed to filter_var() with parmeter FILTER_VALIDATE_EMAIL (CVE-2010-3710).

The remote Oracle Linux 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2011-0196 advisory.

    [5.3.3-1.1]
    - add security fixes for CVE-2010-3710, CVE-2010-4156,       CVE-2010-4645 (#670463)

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

A flaw was found in the way PHP converted certain floating point values from string representation to a number. If a PHP script evaluated an attacker's input in a numeric context, the PHP interpreter could cause high CPU usage until the script execution time limit is reached. This issue only affected i386 systems.
(CVE-2010-4645)

A stack memory exhaustion flaw was found in the way the PHP filter_var() function validated email addresses. An attacker could use this flaw to crash the PHP interpreter by providing excessively long input to be validated as an email address. (CVE-2010-3710)

A memory disclosure flaw was found in the PHP multi-byte string extension. If the mb_strcut() function was called with a length argument exceeding the input string size, the function could disclose a portion of the PHP interpreter's memory. (CVE-2010-4156)

After installing the updated packages, the httpd daemon must be restarted for the update to take effect.

The remote host is affected by the vulnerability described in GLSA-201110-06 (PHP: Multiple vulnerabilities)
