Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

Updated PHP packages that fix several security issues are now
available for Red Hat Enterprise Linux 5.

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.

A number of buffer overflow flaws were found in the PHP session
the str_replace() function
and the imap_mail_compose()
function. If very long strings were passed to the str_replace()
function, an integer overflow could occur in memory allocation. If a
script used the imap_mail_compose() function to create a new MIME
message based on an input body from an untrusted source, it could
result in a heap overflow. An attacker with access to a PHP
application affected by any these issues could trigger the flaws and
possibly execute arbitrary code as the 'apache' user. (CVE-2007-0906)

When unserializing untrusted data on 64-bit platforms, the
zend_hash_init() function could be forced into an infinite loop,
consuming CPU resources for a limited time, until the script timeout
alarm aborted execution of the script. (CVE-2007-0988)

If the wddx extension was used to import WDDX data from an untrusted
source, certain WDDX input packets could expose a random portion of
heap memory. (CVE-2007-0908)

If the odbc_result_all() function was used to display data from a
database, and the database table contents were under an attacker's
control, a format string vulnerability was possible which could allow
arbitrary code execution. (CVE-2007-0909)

A one byte memory read always occurs before the beginning of a buffer.
This could be triggered, for example, by any use of the header()
function in a script. However it is unlikely that this would have any
effect. (CVE-2007-0907)

Several flaws in PHP could allow attackers to 'clobber' certain
super-global variables via unspecified vectors. (CVE-2007-0910)

An input validation bug allowed a remote attacker to trigger a denial
of service attack by submitting an input variable with a
deeply-nested-array. (CVE-2007-1285)

Users of PHP should upgrade to these updated packages which contain
backported patches to correct these issues.
