According to its banner, the version of PHP installed on the remote host is prior to 5.2.7. It is, therefore, affected by multiple vulnerabilities :

  - There is a buffer overflow flaw in the bundled PCRE     library that allows a denial of service attack.
    (CVE-2008-2371)

  - Multiple directory traversal vulnerabilities exist in     functions such as 'posix_access', 'chdir', and 'ftok'     that allow a remote attacker to bypass 'safe_mode'     restrictions. (CVE-2008-2665 and CVE-2008-2666).

  - A buffer overflow flaw in 'php_imap.c' may be triggered     when processing long message headers due to the use of     obsolete API calls. This can be exploited to cause a     denial of service or to execute arbitrary code.
    (CVE-2008-2829)

  - A buffer overflow in the 'imageloadfont' function in     'ext/gd/gd.c' can be triggered when a specially crafted     font is given. This can be exploited to cause a denial     of service or to execute arbitrary code. (CVE-2008-3658)

  - A buffer overflow flaw exists in PHP's internal function     'memnstr' which can be exploited by an attacker using     the delimiter argument to the 'explode' function. This     can be used to cause a denial of service or to execute     arbitrary code. (CVE-2008-3659)

  - When PHP is used as a FastCGI module, an attacker by     requesting a file whose file name extension is preceded     by multiple dots can cause a denial of service.
    (CVE-2008-3660)

  - A heap-based buffer overflow flaw in the mbstring     extension can be triggered via a specially crafted     string containing an HTML entity that is not handled     during Unicode conversion. This can be exploited to     execute arbitrary code.(CVE-2008-5557)

  - Improper initialization of global variables 'page_uid'     and 'page_gid' when PHP is used as an Apache module     allows the bypassing of security restriction due to     SAPI 'php_getuid' function overloading. (CVE-2008-5624)

  - PHP does not enforce the correct restrictions when     'safe_mode' is enabled through a 'php_admin_flag'     setting in 'httpd.conf'. This allows an attacker, by     placing a specially crafted 'php_value' entry in     '.htaccess', to able to write to arbitrary files.
    (CVE-2008-5625)

  - The 'ZipArchive::extractTo' function in the ZipArchive     extension fails to filter directory traversal sequences     from file names. An attacker can exploit this to write     to arbitrary files. (CVE-2008-5658)

  - Under limited circumstances, an attacker can cause a     file truncation to occur when calling the 'dba_replace'     function with an invalid argument. (CVE-2008-7068)

  - A buffer overflow error exists in the function     'date_from_ISO8601' function within file 'xmlrpc.c'     because user-supplied input is improperly validated.
    This can be exploited by a remote attacker to cause a     denial of service or to execute arbitrary code.
    (CVE-2014-8626)

Multiple vulnerabilities was discovered and corrected in php :

The dba_replace function in PHP 5.2.6 and 4.x allows context-dependent attackers to cause a denial of service (file truncation) via a key with the NULL byte. NOTE: this might only be a vulnerability in limited circumstances in which the attacker can modify or add database entries but does not have permissions to truncate the file (CVE-2008-7068).

The JSON_parser function (ext/json/JSON_parser.c) in PHP 5.2.x before 5.2.9 allows remote attackers to cause a denial of service (segmentation fault) via a malformed string to the json_decode API function (CVE-2009-1271).

  - Fixed upstream bug #48378 (exif_read_data() segfaults on     certain corrupted .jpeg files) (CVE-2009-2687).

The php_openssl_apply_verification_policy function in PHP before 5.2.11 does not properly perform certificate validation, which has unknown impact and attack vectors, probably related to an ability to spoof certificates (CVE-2009-3291).

Unspecified vulnerability in PHP before 5.2.11 has unknown impact and attack vectors related to missing sanity checks around exif processing. (CVE-2009-3292)

Unspecified vulnerability in the imagecolortransparent function in PHP before 5.2.11 has unknown impact and attack vectors related to an incorrect sanity check for the color index. (CVE-2009-3293)

The _gdGetColors function in gd_gd.c in PHP 5.2.11 and 5.3.0, and the GD Graphics Library 2.x, does not properly verify a certain colorsTotal structure member, which might allow remote attackers to conduct buffer overflow or buffer over-read attacks via a crafted GD file, a different vulnerability than CVE-2009-3293. NOTE: some of these details are obtained from third-party information (CVE-2009-3546).

The tempnam function in ext/standard/file.c in PHP 5.2.11 and earlier, and 5.3.x before 5.3.1, allows context-dependent attackers to bypass safe_mode restrictions, and create files in group-writable or world-writable directories, via the dir and prefix arguments (CVE-2009-3557).

The posix_mkfifo function in ext/posix/posix.c in PHP 5.2.11 and earlier, and 5.3.x before 5.3.1, allows context-dependent attackers to bypass open_basedir restrictions, and create FIFO files, via the pathname and mode arguments, as demonstrated by creating a .htaccess file (CVE-2009-3558).

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 dba_replace function in PHP 5.2.6 and 4.x allows context-dependent attackers to cause a denial of service (file truncation) via a key with the NULL byte. NOTE: this might only be a vulnerability in limited circumstances in which the attacker can modify or add database entries but does not have permissions to truncate the file (CVE-2008-7068).

The php_openssl_apply_verification_policy function in PHP before 5.2.11 does not properly perform certificate validation, which has unknown impact and attack vectors, probably related to an ability to spoof certificates (CVE-2009-3291).

Unspecified vulnerability in PHP before 5.2.11 has unknown impact and attack vectors related to missing sanity checks around exif processing. (CVE-2009-3292)

Unspecified vulnerability in the imagecolortransparent function in PHP before 5.2.11 has unknown impact and attack vectors related to an incorrect sanity check for the color index. (CVE-2009-3293). However in Mandriva we don't use the bundled libgd source in php per default, there is a unsupported package in contrib named php-gd-bundled that eventually will get updated to pickup these fixes.

The php-suhosin package has been upgraded to 0.9.22 which has better support for apache vhosts.

Packages for 2008.0 are provided for Corporate Desktop 2008.0 customers

This update provides a solution to these vulnerabilities.

    （CVE-2014-8626）

根據其標題，遠端主機上安裝的 PHP 版本舊於 5.2.7。因此，該應用程式受到多個弱點影響：

  - 配套的 PCRE 程式庫中具有一個緩衝區溢位缺陷，會導致拒絕服務攻擊。
    (CVE-2008-2371)

  - 「posix_access」、「chdir」和「ftok」等函式中存在多個目錄遍歷弱點，會讓遠端攻擊者繞過「safe_mode」限制。 (CVE-2008-2665 和 CVE-2008-2666)

  - 處理長訊息標頭時，因為過時的 API 呼叫，可能會觸發「php_imap.c」中的緩衝區溢位缺陷。此缺陷可能會遭到惡意利用，進而引發拒絕服務或執行任意程式碼。
    (CVE-2008-2829)

  - 指定特製字型時，可能會觸發 'ext/gd/gd.c' 之 'imageloadfont' 函式中的緩衝區溢位。此缺陷可能會遭到惡意利用，進而引發拒絕服務或執行任意程式碼。(CVE-2008-3658)

    远程攻击者可利用此缺陷造成拒绝服务或执行任意代码。
    (CVE-2014-8626)

Maksymilian Arciemowicz discovered that PHP did not properly validate arguments to the dba_replace function. If a script passed untrusted input to the dba_replace function, an attacker could truncate the database. This issue only applied to Ubuntu 6.06 LTS, 8.04 LTS, and 8.10. (CVE-2008-7068)

It was discovered that PHP's php_openssl_apply_verification_policy function did not correctly handle SSL certificates with zero bytes in the Common Name. A remote attacker could exploit this to perform a man in the middle attack to view sensitive information or alter encrypted communications. (CVE-2009-3291)

It was discovered that PHP did not properly handle certain malformed images when being parsed by the Exif module. A remote attacker could exploit this flaw and cause the PHP server to crash, resulting in a denial of service. (CVE-2009-3292)

Grzegorz Stachowiak discovered that PHP did not properly enforce restrictions in the tempnam function. An attacker could exploit this issue to bypass safe_mode restrictions. (CVE-2009-3557)

Grzegorz Stachowiak discovered that PHP did not properly enforce restrictions in the posix_mkfifo function. An attacker could exploit this issue to bypass open_basedir restrictions. (CVE-2009-3558)

Bogdan Calin discovered that PHP did not limit the number of temporary files created when handling multipart/form-data POST requests. A remote attacker could exploit this flaw and cause the PHP server to consume all available resources, resulting in a denial of service.
(CVE-2009-4017)

ATTENTION: This update changes previous PHP behaviour by limiting the number of files in a POST request to 50. This may be increased by adding a 'max_file_uploads' directive to the php.ini configuration file.

It was discovered that PHP did not properly enforce restrictions in the proc_open function. An attacker could exploit this issue to bypass safe_mode_protected_env_vars restrictions and possibly execute arbitrary code with application privileges. (CVE-2009-4018).

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.

securityfocus research reports :

A bug that leads to the emptying of the INI file contents if the database key was not found exists in PHP dba extension in versions 5.2.6, 4.4.9 and earlier.

Function dba_replace() are not filtering strings key and value. There is a possibility for the destruction of the file.
