Array index error in the imageRotate function in PHP 5.2.8 and earlier allows context-dependent attackers to read the contents of arbitrary memory locations via a crafted value of the third argument (aka the bgd_color or clrBack argument) for an indexed image.

The remote Oracle Linux 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2009-0338 advisory.

    - ext/gd: fix overflow2 usage for CVE-2007-3996, CVE-2008-3658

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

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

From Red Hat Security Advisory 2009:0337 :

Updated php packages that fix several security issues are now available for Red Hat Enterprise Linux 3 and 4.

This update has been rated as having moderate 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-based buffer overflow flaw was found in PHP's mbstring extension. A remote attacker able to pass arbitrary input to a PHP script using mbstring conversion functions could cause the PHP interpreter to crash or, possibly, execute arbitrary code.
(CVE-2008-5557)

A flaw was found in the handling of the 'mbstring.func_overload' configuration setting. A value set for one virtual host, or in a user's .htaccess file, was incorrectly applied to other virtual hosts on the same server, causing the handling of multibyte character strings to not work correctly. (CVE-2009-0754)

A buffer overflow flaw was found in PHP's imageloadfont function. If a PHP script allowed a remote attacker to load a carefully crafted font file, it could cause the PHP interpreter to crash or, possibly, execute arbitrary code. (CVE-2008-3658)

A flaw was found in the way PHP handled certain file extensions when running in FastCGI mode. If the PHP interpreter was being executed via FastCGI, a remote attacker could create a request which would cause the PHP interpreter to crash. (CVE-2008-3660)

A memory disclosure flaw was found in the PHP gd extension's imagerotate function. A remote attacker able to pass arbitrary values as the 'background color' argument of the function could, possibly, view portions of the PHP interpreter's memory. (CVE-2008-5498)

All php users are advised to upgrade to these updated packages, which contain backported patches to resolve these issues. The httpd web server must be restarted for the changes to take effect.

A cross-site scripting flaw was found in a way PHP reported errors for invalid cookies. If the PHP interpreter had 'display_errors' enabled, a remote attacker able to set a specially crafted cookie on a victim's system could possibly inject arbitrary HTML into an error message generated by PHP. (CVE-2008-5814) - SL5 Only

A memory disclosure flaw was found in the PHP gd extension's imagerotate function. A remote attacker able to pass arbitrary values as the 'background color' argument of the function could, possibly, view portions of the PHP interpreter's memory. (CVE-2008-5498)

The httpd web server must be restarted for the changes to take effect.

The remote host is affected by the vulnerability described in GLSA-201001-03 (PHP: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in PHP. Please review the     CVE identifiers referenced below and the associated PHP release notes     for details.
  Impact :

    A context-dependent attacker could execute arbitrary code via a     specially crafted string containing an HTML entity when the mbstring     extension is enabled. Furthermore a remote attacker could execute     arbitrary code via a specially crafted GD graphics file.
    A remote attacker could also cause a Denial of Service via a malformed     string passed to the json_decode() function, via a specially crafted     ZIP file passed to the php_zip_make_relative_path() function, via a     malformed JPEG image passed to the exif_read_data() function, or via     temporary file exhaustion. It is also possible for an attacker to spoof     certificates, bypass various safe_mode and open_basedir restrictions     when certain criteria are met, perform Cross-site scripting attacks,     more easily perform SQL injection attacks, manipulate settings of other     virtual hosts on the same server via a malicious .htaccess entry when     running on Apache, disclose memory portions, and write arbitrary files     via a specially crafted ZIP archive. Some vulnerabilities with unknown     impact and attack vectors have been reported as well.
  Workaround :

    There is no known workaround at this time.

Update to PHP 5.2.9 A heap-based buffer overflow flaw was found in PHP's mbstring extension. A remote attacker able to pass arbitrary input to a PHP script using mbstring conversion functions could cause the PHP interpreter to crash or, possibly, execute arbitrary code.
(CVE-2008-5557) A directory traversal flaw was found in PHP's ZipArchive::extractTo function. If PHP is used to extract a malicious ZIP archive, it could allow an attacker to write arbitrary files anywhere the PHP process has write permissions. (CVE-2008-5658) A buffer overflow flaw was found in PHP's imageloadfont function. If a PHP script allowed a remote attacker to load a carefully crafted font file, it could cause the PHP interpreter to crash or, possibly, execute arbitrary code.
