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 extension,
the str_replace() function, and the imap_mail_compose() function.
If very long strings under the control of an attacker are passed to the
str_replace() function then an integer overflow could occur in memory
allocation. If a script uses 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 who is able to access a PHP
application affected by any these issues could trigger these flaws and
possibly execute arbitrary code as the ‘apache’ user. (CVE-2007-0906)

If unserializing untrusted data on 64-bit platforms, the zend_hash_init()
function can be forced to enter an infinite loop, consuming CPU resources
for a limited length of time, until the script timeout alarm aborts
execution of the script. (CVE-2007-0988)

If the wddx extension is used to import WDDX data from an untrusted source,
certain WDDX input packets may allow a random portion of heap memory to be
exposed. (CVE-2007-0908)

If the odbc_result_all() function is used to display data from a database,
and the contents of the database table are under the control of an
attacker, a format string vulnerability is possible which could lead to the
execution of arbitrary code. (CVE-2007-0909)

A one byte memory read will always occur before the beginning of a buffer,
which 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 allows attackers to “clobber” certain
super-global variables via unspecified vectors. (CVE-2007-0910)

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

Red Hat would like to thank Stefan Esser for his help diagnosing these issues.
