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.

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.

From Red Hat Security Advisory 2007:0889 :

Updated PHP packages that fix several security issues are now available for Red Hat Enterprise Linux 3.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Web server.

These updated packages address the following vulnerabilities :

Various integer overflow flaws were found in the PHP gd extension script that could be forced to resize images from an untrusted source, possibly allowing a remote attacker to execute arbitrary code as the apache user. (CVE-2007-3996)

An integer overflow flaw was found in the PHP chunk_split function. If a remote attacker was able to pass arbitrary data to the third argument of chunk_split they could possibly execute arbitrary code as the apache user. Note that it is unusual for a PHP script to use the chunk_split function with a user-supplied third argument.
(CVE-2007-2872)

A previous security update introduced a bug into PHP session cookie handling. This could allow an attacker to stop a victim from viewing a vulnerable website if the victim has first visited a malicious web page under the control of the attacker, and that page can set a cookie for the vulnerable website. (CVE-2007-4670)

A flaw was found in the PHP money_format function. If a remote attacker was able to pass arbitrary data to the money_format function this could possibly result in an information leak or denial of service. Note that it is unusual for a PHP script to pass user-supplied data to the money_format function. (CVE-2007-4658)

A flaw was found in the PHP wordwrap function. If a remote attacker was able to pass arbitrary data to the wordwrap function this could possibly result in a denial of service. (CVE-2007-3998)

A bug was found in PHP session cookie handling. This could allow an attacker to create a cross-site cookie insertion attack if a victim follows an untrusted carefully-crafted URL. (CVE-2007-3799)

An infinite-loop flaw was discovered in the PHP gd extension. A script that could be forced to process PNG images from an untrusted source could allow a remote attacker to cause a denial of service.
(CVE-2007-2756)

A flaw was found in the PHP 'ftp' extension. If a PHP script used this extension to provide access to a private FTP server, and passed untrusted script input directly to any function provided by this extension, a remote attacker would be able to send arbitrary FTP commands to the server. (CVE-2007-2509)

Users of PHP should upgrade to these updated packages, which contain backported patches to correct these issues.

(CVE-2007-2756)

This update fixes multiple bugs in PHP :

  - Predictable generaton of an initialization vector (IV)     in the mcrypt extension

  - Additional cookie attributes could be injected via a     session ID.

  - Specially crafted files could cause integer overflows in     gd and leverage them to at least crash gd based     applications.

This update covers CVE IDs CVE-2007-2727, CVE-2007-3472, CVE-2007-3475, CVE-2007-3476 CVE-2007-3477, CVE-2007-3478 and CVE-2007-3799.

Several vulnerabilities have been discovered in PHP version 4, a server-side, HTML-embedded scripting language. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2007-3799     The session_start function allows remote attackers to     insert arbitrary attributes into the session cookie via     special characters in a cookie that is obtained from     various parameters.

  - CVE-2007-3806     A denial of service was possible through a malicious     script abusing the glob() function.

  - CVE-2007-3998     Certain maliciously constructed input to the wordwrap()     function could lead to a denial of service attack.

  - CVE-2007-4657     Large len values of the stspn() or strcspn() functions     could allow an attacker to trigger integer overflows to     expose memory or cause denial of service.

  - CVE-2008-2051     The escapeshellcmd API function could be attacked via     incomplete multibyte chars.

The remote host is running a version of Mac OS X 10.5 or 10.4 that does not have the security update 2008-002 applied. 

This update contains several security fixes for a number of programs.

It was discovered that the patch for CVE-2007-4659 could lead to regressions in some scenarios. The fix has been reverted for now, a revised update will be provided in a future PHP DSA.

For reference the original advisory below :

Several remote vulnerabilities have been discovered in PHP, a server-side, HTML-embedded scripting language. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2007-3799     It was discovered that the session_start() function     allowed the insertion of attributes into the session     cookie.

  - CVE-2007-3998     Mattias Bengtsson and Philip Olausson discovered that a     programming error in the implementation of the     wordwrap() function allowed denial of service through an     infinite loop.

  - CVE-2007-4658     Stanislav Malyshev discovered that a format string     vulnerability in the money_format() function could allow     the execution of arbitrary code.

  - CVE-2007-4659     Stefan Esser discovered that execution control flow     inside the zend_alter_ini_entry() function is handled     incorrectly in case of a memory limit violation.

  - CVE-2007-4660     Gerhard Wagner discovered an integer overflow inside the     chunk_split() function.

  - CVE-2007-5898     Rasmus Lerdorf discovered that incorrect parsing of     multibyte sequences may lead to disclosure of memory     contents.

  - CVE-2007-5899     It was discovered that the output_add_rewrite_var()     function could leak session ID information, resulting in     information disclosure.

This update also fixes two bugs from the PHP 5.2.4 release which don't have security impact according to the Debian PHP security policy (CVE-2007-4657 and CVE-2007-4662 ), but which are fixed nonetheless.

According to its banner, the version of PHP installed on the remote host is older than 4.4.8.  Such versions may be affected by several issues, including integer overflows involving the 'chunk_split', 'strcspn', and 'strspn' functions, and 'safe_mode' / 'open_basedir' bypasses.

This update fixes multiple bugs in php :

  - predictable generaton of an initialization vector (IV)     in the mcrypt extension

  - additional cookie attributes could be injected via a     session id

  - specially crafted files could cause integer overflows in     gd and leverage them to at least crash gd based     applications

  - insufficient validation of parmeters in the substr_count     function

  - predictable generaton of an initialization vector (IV)     in the soap extension

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

Numerous vulnerabilities were discovered in the PHP scripting language that are corrected with this update.

An integer overflow in the substr_compare() function allows context-dependent attackers to read sensitive memory via a large value in the length argument. This only affects PHP5 (CVE-2007-1375).

A stack-based buffer overflow in the zip:// URI wrapper in PECL ZIP 1.8.3 and earlier allowes remote attackers to execute arbitrary code via a long zip:// URL. This only affects Corporate Server 4.0 (CVE-2007-1399).

A CRLF injection vulnerability in the FILTER_VALIDATE_EMAIL filter could allow an attacker to inject arbitrary email headers via a special email address. This only affects Mandriva Linux 2007.1 (CVE-2007-1900).

The mcrypt_create_iv() function calls php_rand_r() with an uninitialized seed variable, thus always generating the same initialization vector, which may allow an attacker to decrypt certain data more easily because of the guessable encryption keys (CVE-2007-2727).

The soap extension calls php_rand_r() with an uninitialized seec variable, which has unknown impact and attack vectors; an issue similar to that affecting mcrypt_create_iv(). This only affects PHP5 (CVE-2007-2728).

The substr_count() function allows attackers to obtain sensitive information via unspecified vectors. This only affects PHP5 (CVE-2007-2748).

An infinite loop was found in the gd extension that could be used to cause a denial of service if a script were forced to process certain PNG images from untrusted sources (CVE-2007-2756).

An integer overflow flaw was found in the chunk_split() function that ould possibly execute arbitrary code as the apache user if a remote attacker was able to pass arbitrary data to the third argument of chunk_split() (CVE-2007-2872).

A flaw in the PHP session cookie handling could allow an attacker to create a cross-site cookie insertion attack if a victim followed an untrusted carefully-crafted URL (CVE-2007-3799).

Various integer overflow flaws were discovered in the PHP gd extension that could allow a remote attacker to execute arbitrary code as the apache user (CVE-2007-3996).

A flaw in the wordwrap() frunction could result in a denial of ervice if a remote attacker was able to pass arbitrary data to the function (CVE-2007-3998).

A flaw in the money_format() function could result in an information leak or denial of service if a remote attacker was able to pass arbitrary data to this function; this situation would be unlikely however (CVE-2007-4658).

A bug in the PHP session cookie handling could allow an attacker to stop a victim from viewing a vulnerable website if the victim first visited a malicious website under the control of the attacker who was able to use that page to set a cookie for the vulnerable website (CVE-2007-4670).

Updated packages have been patched to prevent these issues. In addition, PECL ZIP version 1.8.10 is being provided for Corporate Server 4.0.

Updated PHP packages that fix several security issues are now available for Red Hat Enterprise Linux 4 and 5.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Web server.

Various integer overflow flaws were found in the PHP gd extension. A script that could be forced to resize images from an untrusted source could possibly allow a remote attacker to execute arbitrary code as the apache user. (CVE-2007-3996)

An integer overflow flaw was found in the PHP chunk_split function. If a remote attacker was able to pass arbitrary data to the third argument of chunk_split they could possibly execute arbitrary code as the apache user. Note that it is unusual for a PHP script to use the chunk_script function with a user-supplied third argument.
(CVE-2007-2872)

A previous security update introduced a bug into PHP session cookie handling. This could allow an attacker to stop a victim from viewing a vulnerable website if the victim has first visited a malicious web page under the control of the attacker, and that page can set a cookie for the vulnerable website. (CVE-2007-4670)

A flaw was found in the PHP money_format function. If a remote attacker was able to pass arbitrary data to the money_format function this could possibly result in an information leak or denial of service. Note that is is unusual for a PHP script to pass user-supplied data to the money_format function. (CVE-2007-4658)

A flaw was found in the PHP wordwrap function. If a remote attacker was able to pass arbitrary data to the wordwrap function this could possibly result in a denial of service. (CVE-2007-3998)

A bug was found in PHP session cookie handling. This could allow an attacker to create a cross-site cookie insertion attack if a victim follows an untrusted carefully-crafted URL. (CVE-2007-3799)

An infinite-loop flaw was discovered in the PHP gd extension. A script that could be forced to process PNG images from an untrusted source could allow a remote attacker to cause a denial of service.
(CVE-2007-2756)

Users of PHP should upgrade to these updated packages, which contain backported patches to correct these issues.

According to its banner, the version of PHP installed on the remote host is older than 5.2.4.  Such versions may be affected by various issues, including but not limited to several overflows.
