Oracle Linux 4 : php (ELSA-2006-0730 / ELSA-2006-0669)
High Nessus Plugin ID 67421
SynopsisThe remote Oracle Linux host is missing a security update.
DescriptionUpdated PHP packages that fix a security issue are now available.
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.
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.
From Red Hat Security Advisory 2006:0730 :
The Hardened-PHP Project discovered an overflow in the PHP htmlentities() and htmlspecialchars() routines. If a PHP script used the vulnerable functions to parse UTF-8 data, a remote attacker sending a carefully crafted request could trigger the overflow and potentially execute arbitrary code as the 'apache' user.
From Red Hat Security Advisory 2006:0669 :
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.
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)
SolutionUpdate the affected php packages.
