Vulnerability Assessment Details
Check for the version of the php packages
Detailed Explanation for this Vulnerability Assessment
Updated PHP packages that fix multiple security issues are now available
for Red Hat Enterprise Linux 3 and 4.
This update has been rated as having moderate 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 flaw was found in the way PHP registers global variables during a file
upload request. A remote attacker could submit a carefully crafted
multipart/form-data POST request that would overwrite the $GLOBALS array,
altering expected script behavior, and possibly leading to the execution of
arbitrary PHP commands. Please note that this vulnerability only affects
installations which have register_globals enabled in the PHP configuration
file, which is not a default or recommended option. The Common
Vulnerabilities and Exposures project assigned the name CVE-2005-3390 to
A flaw was found in the PHP parse_str() function. If a PHP script passes
only one argument to the parse_str() function, and the script can be forced
to abort execution during operation (for example due to the memory_limit
setting), the register_globals may be enabled even if it is disabled in the
PHP configuration file. This vulnerability only affects installations that
have PHP scripts using the parse_str function in this way. (CVE-2005-3389)
A Cross-Site Scripting flaw was found in the phpinfo() function. If a
victim can be tricked into following a malicious URL to a site with a page
or HTML content into the displayed page or steal data such as cookies.
This vulnerability only affects installations which permit users to view the
output of the phpinfo() function. As the phpinfo() function outputs a
large amount of information about the current state of PHP, it should only
be used during debugging or if protected by authentication. (CVE-2005-3388)
A denial of service flaw was found in the way PHP processes EXIF image
data. It is possible for a possible hacker to cause PHP to crash by supplying
carefully crafted EXIF image data. (CVE-2005-3353)
Users of PHP should upgrade to these updated packages, which contain
backported patches that resolve these issues.
