Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

Description :

A flaw was found in the way PHP parsed multipart HTTP POST requests. A
specially crafted request could cause PHP to use an excessive amount
of CPU time. (CVE-2015-4024)

An uninitialized pointer use flaw was found in PHP's Exif extension. A
specially crafted JPEG or TIFF file could cause a PHP application
using the exif_read_data() function to crash or, possibly, execute
arbitrary code with the privileges of the user running that PHP
application. (CVE-2015-0232)

An integer overflow flaw leading to a heap-based buffer overflow was
found in the way PHP's FTP extension parsed file listing FTP server
responses. A malicious FTP server could use this flaw to cause a PHP
application to crash or, possibly, execute arbitrary code.
(CVE-2015-4022)

Multiple flaws were discovered in the way PHP performed object
unserialization. Specially crafted input processed by the
unserialize() function could cause a PHP application to crash or,
possibly, execute arbitrary code. (CVE-2015-0273, CVE-2015-2787,
CVE-2015-4147, CVE-2015-4148, CVE-2015-4599, CVE-2015-4600,
CVE-2015-4601, CVE-2015-4602, CVE-2015-4603)

It was found that certain PHP functions did not properly handle file
names containing a NULL character. A remote attacker could possibly
use this flaw to make a PHP script access unexpected files and bypass
intended file system access restrictions. (CVE-2015-4026,
CVE-2015-3411, CVE-2015-3412, CVE-2015-4598)

Multiple flaws were found in the way the way PHP's Phar extension
parsed Phar archives. A specially crafted archive could cause PHP to
crash or, possibly, execute arbitrary code when opened.
(CVE-2015-2301, CVE-2015-2783, CVE-2015-3307, CVE-2015-3329,
CVE-2015-4021)

A heap buffer overflow flaw was found in the
enchant_broker_request_dict() function of PHP's enchant extension. An
attacker able to make a PHP application enchant dictionaries could
possibly cause it to crash. (CVE-2014-9705)

A buffer over-read flaw was found in the GD library used by the PHP gd
extension. A specially crafted GIF file could cause a PHP application
using the imagecreatefromgif() function to crash. (CVE-2014-9709)

A double free flaw was found in zend_ts_hash_graceful_destroy()
function in the PHP ZTS module. This flaw could possibly cause a PHP
application to crash. (CVE-2014-9425)

After installing the updated packages, the httpd daemon must be
restarted for the update to take effect.
