php security update

Updated PHP packages that fix multiple security issues are now available
for Red Hat Enterprise Linux 2.1.

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.

The phpinfo() PHP function did not properly sanitize long strings. An
attacker could use this to perform cross-site scripting attacks against
sites that have publicly-available PHP scripts that call phpinfo().
(CVE-2006-0996)

The error handling output was found to not properly escape HTML output in
certain cases. An attacker could use this flaw to perform cross-site
scripting attacks against sites where both display_errors and html_errors
are enabled. (CVE-2006-0208)

A buffer overflow flaw was discovered in uw-imap, the University of
Washington's IMAP Server. php-imap is compiled against the static c-client
libraries from imap and therefore needed to be recompiled against the fixed
version. (CVE-2005-2933)

The wordwrap() PHP function did not properly check for integer overflow in
the handling of the "break" parameter. An attacker who could control the
string passed to the "break" parameter could cause a heap overflow.
(CVE-2006-1990)

Users of PHP should upgrade to these updated packages, which contain
backported patches that resolve these issues.

Before applying this update, make sure all previously released errata
