(RHSA-2006:0276) php security update

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 html_entity_decode() PHP function was found to not be binary safe. An
attacker could use this flaw to disclose a certain part of the memory. In
order for this issue to be exploitable the target site would need to have a
PHP script which called the “html_entity_decode()” function with untrusted
input from the user and displayed the result. (CVE-2006-1490)

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)

An input validation error was found in the “mb_send_mail()” function. An
attacker could use this flaw to inject arbitrary headers in a mail sent via
a script calling the “mb_send_mail()” function where the “To” parameter can
be controlled by the attacker. (CVE-2005-3883)

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. This issue only affected Red Hat Enterprise Linux 3.
(CVE-2005-2933).

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