RHEL 3 / 4 : php (RHSA-2007:0076)

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 3 and 4.

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
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
