php security update

CentOS Errata and Security Advisory CESA-2006:0669

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.
