Vulnerability Assessment Summary Check for the version of the php packages Detailed Explanation for this Vulnerability Assessment Updated PHP packages that fix multiple 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 response-splitting issue was discovered in the PHP session handling. If a remote attacker can force a carefully crafted session identifier to be used, a cross-site-scripting or response-splitting attack could be possible. (CVE-2006-3016) A buffer overflow was discovered in the PHP sscanf() function. If a script used the sscanf() function with positional arguments in the format string, a remote attacker sending a carefully crafted request could execute arbitrary code as the 'apache' user. (CVE-2006-4020) An integer overflow was discovered in the PHP wordwrap() and str_repeat() functions. If a script running on a 64-bit server used either of these functions on untrusted user data, a remote attacker sending a carefully crafted request might be able to cause a heap overflow. (CVE-2006-4482) A buffer overflow was discovered in the PHP gd extension. If a script was set up to process GIF images from untrusted sources using the gd extension, a remote attacker could cause a heap overflow. (CVE-2006-4484) An integer overflow was discovered in the PHP memory allocation handling. On 64-bit platforms, the "memory_limit" setting was not enforced correctly, which could permit a denial of service attack by a remote user. (CVE-2006-4486) Users of PHP should upgrade to these updated packages which contain backported patches to correct these issues. These packages also contain a fix for a bug where certain input strings to the metaphone() function could cause memory corruption.
