"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."
