The remote host is affected by the vulnerability described in GLSA-200811-05 (PHP: Multiple vulnerabilities)

    Several vulnerabilitites were found in PHP:
    PHP ships a     vulnerable version of the PCRE library which allows for the     circumvention of security restrictions or even for remote code     execution in case of an application which accepts user-supplied regular     expressions (CVE-2008-0674).
    Multiple crash issues in several     PHP functions have been discovered.
    Ryan Permeh reported that     the init_request_info() function in sapi/cgi/cgi_main.c does not     properly consider operator precedence when calculating the length of     PATH_TRANSLATED (CVE-2008-0599).
    An off-by-one error in the     metaphone() function may lead to memory corruption.
    Maksymilian Arciemowicz of SecurityReason Research reported an     integer overflow, which is triggerable using printf() and related     functions (CVE-2008-1384).
    Andrei Nigmatulin reported a     stack-based buffer overflow in the FastCGI SAPI, which has unknown     attack vectors (CVE-2008-2050).
    Stefan Esser reported that PHP     does not correctly handle multibyte characters inside the     escapeshellcmd() function, which is used to sanitize user input before     its usage in shell commands (CVE-2008-2051).
    Stefan Esser     reported that a short-coming in PHP's algorithm of seeding the random     number generator might allow for predictible random numbers     (CVE-2008-2107, CVE-2008-2108).
    The IMAP extension in PHP uses     obsolete c-client API calls making it vulnerable to buffer overflows as     no bounds checking can be done (CVE-2008-2829).
    Tavis Ormandy     reported a heap-based buffer overflow in pcre_compile.c in the PCRE     version shipped by PHP when processing user-supplied regular     expressions (CVE-2008-2371).
    CzechSec reported that specially     crafted font files can lead to an overflow in the imageloadfont()     function in ext/gd/gd.c, which is part of the GD extension     (CVE-2008-3658).
    Maksymilian Arciemowicz of SecurityReason     Research reported that a design error in PHP's stream wrappers allows     to circumvent safe_mode checks in several filesystem-related PHP     functions (CVE-2008-2665, CVE-2008-2666).
    Laurent Gaffie     discovered a buffer overflow in the internal memnstr() function, which     is used by the PHP function explode() (CVE-2008-3659).
    An     error in the FastCGI SAPI when processing a request with multiple dots     preceding the extension (CVE-2008-3660).
  Impact :

    These vulnerabilities might allow a remote attacker to execute     arbitrary code, to cause a Denial of Service, to circumvent security     restrictions, to disclose information, and to manipulate files.
  Workaround :

    There is no known workaround at this time.

CVE reports :

Integer overflow in PHP 5.2.5 and earlier allows context-dependent attackers to cause a denial of service and possibly have unspecified other impact via a printf format parameter with a large width specifier, related to the php_sprintf_appendstring function in formatted_print.c and probably other functions for formatted strings (aka *printf functions).

It was discovered that PHP did not properly check the length of the string parameter to the fnmatch function. An attacker could cause a denial of service in the PHP interpreter if a script passed untrusted input to the fnmatch function. (CVE-2007-4782)

Maksymilian Arciemowicz discovered a flaw in the cURL library that allowed safe_mode and open_basedir restrictions to be bypassed. If a PHP application were tricked into processing a bad file:// request, an attacker could read arbitrary files. (CVE-2007-4850)

Rasmus Lerdorf discovered that the htmlentities and htmlspecialchars functions did not correctly stop when handling partial multibyte sequences. A remote attacker could exploit this to read certain areas of memory, possibly gaining access to sensitive information. This issue affects Ubuntu 8.04 LTS, and an updated fix is included for Ubuntu 6.06 LTS, 7.04 and 7.10. (CVE-2007-5898)

It was discovered that the output_add_rewrite_var function would sometimes leak session id information to forms targeting remote URLs.
Malicious remote sites could use this information to gain access to a PHP application user's login credentials. This issue only affects Ubuntu 8.04 LTS. (CVE-2007-5899)

It was discovered that PHP did not properly calculate the length of PATH_TRANSLATED. If a PHP application were tricked into processing a malicious URI, and attacker may be able to execute arbitrary code with application privileges. (CVE-2008-0599)

An integer overflow was discovered in the php_sprintf_appendstring function. Attackers could exploit this to cause a denial of service.
(CVE-2008-1384)

Andrei Nigmatulin discovered stack-based overflows in the FastCGI SAPI of PHP. An attacker may be able to leverage this issue to perform attacks against PHP applications. (CVE-2008-2050)

It was discovered that the escapeshellcmd did not properly process multibyte characters. An attacker may be able to bypass quoting restrictions and possibly execute arbitrary code with application privileges. (CVE-2008-2051)

It was discovered that the GENERATE_SEED macro produced a predictable seed under certain circumstances. Attackers may by able to easily predict the results of the rand and mt_rand functions. (CVE-2008-2107, CVE-2008-2108)

Tavis Ormandy discovered that the PCRE library did not correctly handle certain in-pattern options. An attacker could cause PHP applications using pcre to crash, leading to a denial of service.
USN-624-1 fixed vulnerabilities in the pcre3 library. This update provides the corresponding update for PHP. (CVE-2008-2371)

It was discovered that php_imap used obsolete API calls. If a PHP application were tricked into processing a malicious IMAP request, an attacker could cause a denial of service or possibly execute code with application privileges. (CVE-2008-2829).

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.

A vulnerability in PHP allowed context-dependent attackers to cause a denial of service (crash) via a certain long string in the glob() or fnmatch() functions (CVE-2007-4782).

A vulnerability in the cURL library in PHP allowed context-dependent attackers to bypass safe_mode and open_basedir restrictions and read arbitrary files using a special URL request (CVE-2007-4850).

An integer overflow in PHP allowed context-dependent attackers to cause a denial of serivce via a special printf() format parameter (CVE-2008-1384).

A stack-based buffer overflow in the FastCGI SAPI in PHP has unknown impact and attack vectors (CVE-2008-2050).

A buffer overflow in the imageloadfont() function in PHP allowed context-dependent attackers to cause a denial of service (crash) and potentially execute arbitrary code via a crafted font file (CVE-2008-3658).

A buffer overflow in the memnstr() function allowed context-dependent attackers to cause a denial of service (crash) and potentially execute arbitrary code via the delimiter argument to the explode() function (CVE-2008-3659).

PHP, when used as a FastCGI module, allowed remote attackers to cause a denial of service (crash) via a request with multiple dots preceding the extension (CVE-2008-3660).

An array index error in the imageRotate() function in PHP allowed context-dependent attackers to read the contents of arbitrary memory locations via a crafted value of the third argument to the function for an indexed image (CVE-2008-5498).

The updated packages have been patched to correct these issues.

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

  - CVE-2007-3806     The glob function allows context-dependent attackers to     cause a denial of service and possibly execute arbitrary     code via an invalid value of the flags parameter.

  - CVE-2008-1384     Integer overflow allows context-dependent attackers to     cause a denial of service and possibly have other impact     via a printf format parameter with a large width     specifier.

  - CVE-2008-2050     Stack-based buffer overflow in the FastCGI SAPI.

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

According to its banner, the version of PHP installed on the remote host is older than 5.2.6.  Such versions may be affected by the following issues :

  - A stack-based buffer overflow in FastCGI SAPI.

  - An integer overflow in printf().

  - An security issue arising from improper calculation     of the length of PATH_TRANSLATED in cgi_main.c.

  - A safe_mode bypass in cURL.

  - Incomplete handling of multibyte chars inside     escapeshellcmd().

  - Issues in the bundled PCRE fixed by version 7.6.

This update of php5 fixes :

  - possible stack-based buffer overflow CVE-2008-2050

  - incomplete escapeshellcmd() CVE-2008-2051

  - printf() integer overflow CVE-2008-1384

  - insecure GENERATE_SEED macro CVE-2008-2107
