Updated PHP packages that fix several security issues are now available for Red Hat Enterprise Linux 2.1.

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 number of buffer overflow flaws were found in the PHP session extension; the str_replace() function; and the imap_mail_compose() function. If very long strings were passed to the str_replace() function, an integer overflow could occur in memory allocation. If a script used the imap_mail_compose() function to create a new MIME message based on an input body from an untrusted source, it could result in a heap overflow. An attacker with access to a PHP application affected by any these issues could trigger the flaws and possibly execute arbitrary code as the 'apache' user. (CVE-2007-0906)

When unserializing untrusted data on 64-bit platforms, the zend_hash_init() function could be forced into an infinite loop, consuming CPU resources for a limited time, until the script timeout alarm aborted execution of the script. (CVE-2007-0988)

If the wddx extension was used to import WDDX data from an untrusted source, certain WDDX input packets could expose a random portion of heap memory. (CVE-2007-0908)

If the odbc_result_all() function was used to display data from a database, and the database table contents were under an attacker's control, a format string vulnerability was possible which could allow arbitrary code execution. (CVE-2007-0909)

A one byte memory read always occurs before the beginning of a buffer.
This could be triggered, for example, by any use of the header() function in a script. However it is unlikely that this would have any effect. (CVE-2007-0907)

Several flaws in PHP could allow attackers to 'clobber' certain super-global variables via unspecified vectors. (CVE-2007-0910)

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

Red Hat would like to thank Stefan Esser for his help diagnosing these issues.

The remote Redhat Enterprise Linux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2007:0076 advisory.

  - security flaw (CVE-2007-0906, CVE-2007-0907, CVE-2007-0908, CVE-2007-0909, CVE-2007-0910, CVE-2007-0988)

  - php session extension information leak (CVE-2007-1380)

  - php session extension global variable clobber (CVE-2007-1701)

  - php imap_mail_compose() buffer overflow via type.parameters (CVE-2007-1825)

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

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.

According to its banner, the version of PHP installed on the remote host is older than 4.4.5.  Such versions may be affected by several issues, including buffer overflows, format string vulnerabilities, arbitrary code execution, 'safe_mode' and 'open_basedir' bypasses, and clobbering of super-globals.

An input validation bug allowed a remote attacker to trigger a denial of service attack by submitting an input variable with a deeply-nested-array. (CVE-2007-1285)

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 5.2.1.  Such versions may be affected by several issues, including buffer overflows, format string vulnerabilities, arbitrary code execution, 'safe_mode' and 'open_basedir' bypasses, and clobbering of super-globals.

The remote host is running PHP less than 5.2.0.  This version is vulnerable to around 180 bugs.  An attacker exploiting these flaws would be able to impact confidentiality, integrity, and availability.
