Buffer overflow in the make_http_soap_request function in PHP before 5.2.2 has unknown impact and remote attack vectors, possibly related to "/" (slash) characters.

From Red Hat Security Advisory 2007:0348 :

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

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

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

A heap buffer overflow flaw was found in the PHP 'xmlrpc' extension. A PHP script which implements an XML-RPC server using this extension could allow a remote attacker to execute arbitrary code as the 'apache' user. Note that this flaw does not affect PHP applications using the pure-PHP XML_RPC class provided in /usr/share/pear.
(CVE-2007-1864)

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)

A buffer overflow flaw was found in the PHP 'soap' extension, regarding the handling of an HTTP redirect response when using the SOAP client provided by this extension with an untrusted SOAP server.
No mechanism to trigger this flaw remotely is known. (CVE-2007-2510)

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

The following issues have been fixed :

  - missing open_basedir and safe_mode restriction.
    (CVE-2007-3007)

  - chunk_split() integer overflow. (CVE-2007-2872)

  - DoS condition in libgd's image processing.
    (CVE-2007-2756)

  - possible super-global overwrite inside     import_request_variables(). (CVE-2007-1396)

  - buffer overflow inside user_filter_factory_create().
    (CVE-2007-2511)

  - remotely trigger-able buffer overflow inside bundled     libxmlrpc. (CVE-2007-1864)

  - CRLF injection inside ftp_putcmd(). (CVE-2007-2509)

  - remotely trigger-able buffer overflow inside     make_http_soap_request(). (CVE-2007-2510)

  - MOPB-41-2007:PHP 5 sqlite_udf_decode_binary() Buffer     Overflow Vulnerability. (CVE-2007-0906)

  - MOPB-03-2007: deep recursion DoS (CVE-2007-1285)

A flaw was discovered in the FTP command handler in PHP. Commands were not correctly filtered for control characters. An attacker could issue arbitrary FTP commands using specially crafted arguments.
(CVE-2007-2509)

Ilia Alshanetsky discovered a buffer overflow in the SOAP request handler in PHP. Remote attackers could send a specially crafted SOAP request and execute arbitrary code with web server privileges.
(CVE-2007-2510)

Ilia Alshanetsky discovered a buffer overflow in the user filter factory in PHP. A local attacker could create a specially crafted script and execute arbitrary code with web server privileges.
(CVE-2007-2511)

Gregory Beaver discovered that the PEAR installer did not validate installation paths. If a user were tricked into installing a malicious PEAR package, an attacker could overwrite arbitrary files.
(CVE-2007-2519).

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.

The following issues have been fixed in PHP, which were spotted by the MOPB project or fixed in PHP 5.2.3 release :

  - missing open_basedir and safe_mode restriction     (CVE-2007-3007)

  - chunk_split() integer overflow (CVE-2007-2872)

  - DoS condition in libgd's image processing     (CVE-2007-2756)

  - possible super-global overwrite inside     import_request_variables() (CVE-2007-1396)

  - buffer overflow inside user_filter_factory_create()     (CVE-2007-2511)

  - remotely trigger-able buffer overflow inside bundled     libxmlrpc (CVE-2007-1864)

  - CRLF injection inside ftp_putcmd() (CVE-2007-2509)

  - remotely trigger-able buffer overflow inside     make_http_soap_request() (CVE-2007-2510)

  - MOPB-41-2007:PHP 5 sqlite_udf_decode_binary() Buffer     Overflow Vulnerability (CVE-2007-0906)

  - MOPB-03-2007: deep recursion DoS (CVE-2007-1285)

The remote host is affected by the vulnerability described in GLSA-200705-19 (PHP: Multiple vulnerabilities)

    Several vulnerabilities were found in PHP, most of them during the     Month Of PHP Bugs (MOPB) by Stefan Esser. The most severe of these     vulnerabilities are integer overflows in wbmp.c from the GD library     (CVE-2007-1001) and in the substr_compare() PHP 5 function     (CVE-2007-1375). Ilia Alshanetsky also reported a buffer overflow in     the make_http_soap_request() and in the user_filter_factory_create()     functions (CVE-2007-2510, CVE-2007-2511), and Stanislav Malyshev     discovered another buffer overflow in the bundled XMLRPC library     (CVE-2007-1864). Additionally, the session_regenerate_id() and the     array_user_key_compare() functions contain a double-free vulnerability     (CVE-2007-1484, CVE-2007-1521). Finally, there exist implementation     errors in the Zend engine, in the mb_parse_str(), the unserialize() and     the mail() functions and other elements.
  Impact :

    Remote attackers might be able to exploit these issues in PHP     applications making use of the affected functions, potentially     resulting in the execution of arbitrary code, Denial of Service,     execution of scripted contents in the context of the affected site,     security bypass or information leak.
  Workaround :

    There is no known workaround at this time.

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-2007-2509     It was discovered that missing input sanitising inside     the ftp extension permits an attacker to execute     arbitrary FTP commands. This requires the attacker to     already have access to the FTP server.

  - CVE-2007-2510     It was discovered that a buffer overflow in the SOAP     extension permits the execution of arbitrary code.

The oldstable distribution (sarge) doesn't include php5.

A heap buffer overflow flaw was found in the xmlrpc extension for PHP.
A script that implements an XML-RPC server using this extension could allow a remote attacker to execute arbitrary code as the apache user.
This flaw does not, however, affect PHP applications using the pure-PHP XML_RPC class provided via PEAR (CVE-2007-1864).

A flaw was found in the ftp extension for PHP. A script using this extension to provide access to a private FTP server and which passed untrusted script input directly to any function provided by this extension could allow a remote attacker to send arbitrary FTP commands to the server (CVE-2007-2509).

A buffer overflow flaw was found in the soap extension for PHP in the handling of an HTTP redirect response when using the SOAP client provided by the extension with an untrusted SOAP server (CVE-2007-2510).

A buffer overflow in the user_filter_factory_create() function has unknown impact and local attack vectors (CVE-2007-2511).

Updated packages have been patched to prevent this issue.

The remote host is running a version of PHP lower than 4.4.7 or 5.2.2.  This version is vulnerable to a number of remote issues.  At least one of these issues is related to a buffer overflow attack.  An attacker exploiting these flaws would be able to impact confidentiality, integrity, and availability. 

According to its banner, the version of PHP installed on the remote host is older than 4.4.7 / 5.2.2.  Such versions may be affected by several issues, including buffer overflows in the GD library.
