(RHSA-2014:1765) Important: php54-php security update

PHP is an HTML-embedded scripting language commonly used with the Apache
HTTP Server.

A buffer overflow flaw was found in the Exif extension. A specially crafted
JPEG or TIFF file could cause a PHP application using the exif_thumbnail()
function to crash or, possibly, execute arbitrary code. (CVE-2014-3670)

Multiple buffer overflow flaws were found in the way PHP parsed DNS
responses. A malicious DNS server or a man-in-the-middle attacker could
use these flaws to crash or, possibly, execute arbitrary code with the
privileges of a PHP application that uses the dns_get_record() function.
(CVE-2014-4049, CVE-2014-3597)

Multiple denial of service flaws were found in the File Information
(fileinfo) extension. A remote attacker could use these flaws to cause a
PHP application using fileinfo to consume an excessive amount of CPU and
possibly crash. (CVE-2013-7345, CVE-2014-0237, CVE-2014-0238,
CVE-2014-1943, CVE-2014-3538)

Multiple boundary check flaws were found in the File Information
(fileinfo) extension. A remote attacker could use these flaws to cause a
PHP application using fileinfo to crash. (CVE-2014-0207, CVE-2014-2270,
CVE-2014-3478, CVE-2014-3479, CVE-2014-3480, CVE-2014-3487, CVE-2014-3587,
CVE-2014-3710)

A type confusion issue was found in PHP’s phpinfo() function. A malicious
script author could possibly use this flaw to disclose certain portions of
server memory. (CVE-2014-4721)

A type confusion issue was found in the SPL ArrayObject and
SPLObjectStorage classes’ unserialize() method. A remote attacker able to
submit specially crafted input to a PHP application, which would then
unserialize this input using one of the aforementioned methods, could use
this flaw to execute arbitrary code with the privileges of the user running
that PHP application. (CVE-2014-3515)

Two use-after-free flaws were found in the way PHP handled certain Standard
PHP Library (SPL) Iterators and ArrayIterators. A malicious script author
could possibly use either of these flaws to disclose certain portions of
server memory. (CVE-2014-4670, CVE-2014-4698)

An integer overflow flaw was found in the way custom objects were
unserialized. Specially crafted input processed by the unserialize()
function could cause a PHP application to crash. (CVE-2014-3669)

It was found that PHP’s gd extension did not properly handle file names
with a null character. A remote attacker could possibly use this flaw to
make a PHP application access unexpected files and bypass intended file
system access restrictions. (CVE-2014-5120)

A NULL pointer dereference flaw was found in the gdImageCreateFromXpm()
function of PHP’s gd extension. A remote attacker could use this flaw to
crash a PHP application using gd via a specially crafted X PixMap (XPM)
file. (CVE-2014-2497)

A buffer over-read flaw was found in the way the DateInterval class parsed
interval specifications. An attacker able to make a PHP application parse a
specially crafted specification using DateInterval could possibly cause the
PHP interpreter to crash. (CVE-2013-6712)

An out of bounds read flaw was found in the way the xmlrpc extension parsed
dates in the ISO 8601 format. A specially crafted XML-RPC request or
response could possibly cause a PHP application to crash. (CVE-2014-3668)

The CVE-2014-0207, CVE-2014-0237, CVE-2014-0238, CVE-2014-3478,
CVE-2014-3479, CVE-2014-3480, CVE-2014-3487, and CVE-2014-3710 issues were
discovered by Francisco Alonso of Red Hat Product Security; the
CVE-2014-3538 issue was discovered by Jan Kaluža of the Red Hat Web Stack
Team; the CVE-2014-3597 issue was discovered by David Kutálek of Red Hat
BaseOS QE.

All php54-php users are advised to upgrade to these updated packages, which
contain backported patches to correct these issues. After installing the
updated packages, the httpd service must be restarted for the update to
take effect.
