Multiple HTTP response splitting vulnerabilities in PHP 5.1.1 allow remote attackers to inject arbitrary HTTP headers via a crafted Set-Cookie header, related to the (1) session extension (aka ext/session) and the (2) header function.

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.

According to its banner, the version of PHP 5.1.x installed on the remote host is older than 5.1.2.  Such versions may be affected by multiple vulnerabilities :

  - A format string vulnerability exists in the     error-reporting feature of the mysqli extension.
    (CVE-2006-0200)

  - Multiple HTTP response splitting vulnerabilities exist     that would allow remote attackers to inject arbitrary     HTTP headers via a crafted Set-Cookie header.     (CVE-2006-0207)

  - Multiple cross-site scripting vulnerabilities exist when     display_errors and html_errors are on. (CVE-2006-0208)

Several remote vulnerabilities have been discovered in PHP, a server-side, HTML-embedded scripting language, which may lead to the execution of arbitrary code. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2006-0207     Stefan Esser discovered HTTP response splitting     vulnerabilities in the session extension. This only     affects Debian 3.1 (Sarge).

  - CVE-2006-4486     Stefan Esser discovered that an integer overflow in     memory allocation routines allows the bypass of memory     limit restrictions. This only affects Debian 3.1 (Sarge)     on 64 bit architectures.

  - CVE-2007-1864     It was discovered that a buffer overflow in the xmlrpc     extension allows the execution of arbitrary code.

The remote host is affected by the vulnerability described in GLSA-200603-22 (PHP: Format string and XSS vulnerabilities)

    Stefan Esser of the Hardened PHP project has reported a few     vulnerabilities found in PHP:
    Input passed to the session     ID in the session extension isn't properly sanitised before being     returned to the user via a 'Set-Cookie' HTTP header, which can contain     arbitrary injected data.
    A format string error while     processing error messages using the mysqli extension in version 5.1 and     above.
  Impact :

    By sending a specially crafted request, a remote attacker can     exploit this vulnerability to inject arbitrary HTTP headers, which will     be included in the response sent to the user. The format string     vulnerability may be exploited to execute arbitrary code.
  Workaround :

    There is no known workaround at this time.

Stefan Esser discovered that the 'session' module did not sufficiently verify the validity of the user-supplied session ID. A remote attacker could exploit this to insert arbitrary HTTP headers into the response sent by the PHP application, which could lead to HTTP Response Splitting (forging of arbitrary responses on behalf the PHP application) and Cross Site Scripting (XSS) (execution of arbitrary web script code in the client's browser) attacks. (CVE-2006-0207)

PHP applications were also vulnerable to several Cross Site Scripting (XSS) flaws if the options 'display_errors' and 'html_errors' were enabled. Please note that enabling 'html_errors' is not recommended for production systems. (CVE-2006-0208).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Multiple response splitting vulnerabilities in PHP allow remote attackers to inject arbitrary HTTP headers via unknown attack vectors, possibly involving a crafted Set-Cookie header, related to the (1) session extension (aka ext/session) and the (2) header function.
(CVE-2006-0207)

Multiple cross-site scripting (XSS) vulnerabilities in PHP allow remote attackers to inject arbitrary web script or HTML via unknown attack vectors in 'certain error conditions.' (CVE-2006-0208). This issue does not affect Corporate Server 2.1.

Updated packages are patched to address these issues. Users must execute 'service httpd restart' for the new PHP modules to be loaded by Apache.
