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 allow 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.
