Fedora Core 5 2007-287: php

Vulnerability Assessment Summary
Check for the version of the php package

Detailed Explanation for this Vulnerability Assessment

The remote host is missing the patch for the advisory FEDORA-2007-287 (php).

PHP is an HTML-embedded scripting language. PHP attempts to make it
easy for developers to write dynamically generated webpages. PHP also
offers built-in database integration for several commercial and
non-commercial database management systems, so writing a
database-enabled webpage with PHP is fairly simple. The most common
use of PHP coding is probably as a replacement for CGI scripts. The
mod_php module enables the Apache Web server to understand and process
the embedded PHP language in Web pages.

Update Information:

This update fixes a number of security issues in PHP.

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 a possible hacker 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. A possible hacker 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 permit 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 a possible hacker, 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 permits attackers to 'clobber'
certain super-global variables via unspecified vectors.
(CVE-2007-0910)

The Fedora Project would like to thank Stefan Esser for his
help diagnosing these issues.
