Test ID:1.3.6.1.4.1.25623.1.0.70660
Category:Red Hat Local Security Checks
Title:RedHat Security Advisory RHSA-2012:0033
Summary:NOSUMMARY
Description:Description:
The remote host is missing updates announced in
advisory RHSA-2012:0033.

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

It was found that the hashing routine used by PHP arrays was susceptible
to predictable hash collisions. If an HTTP POST request to a PHP
application contained many parameters whose names map to the same hash
value, a large amount of CPU time would be consumed. This flaw has been
mitigated by adding a new configuration directive, max_input_vars, that
limits the maximum number of parameters processed per request. By
default, max_input_vars is set to 1000. (CVE-2011-4885)

A use-after-free flaw was found in the PHP substr_replace() function. If a
PHP script used the same variable as multiple function arguments, a remote
attacker could possibly use this to crash the PHP interpreter or, possibly,
execute arbitrary code. (CVE-2011-1148)

An integer overflow flaw was found in the PHP exif extension. On 32-bit
systems, a specially-crafted image file could cause the PHP interpreter to
crash or disclose portions of its memory when a PHP script tries to extract
Exchangeable image file format (Exif) metadata from the image file.
(CVE-2011-4566)

An insufficient input validation flaw, leading to a buffer over-read, was
found in the PHP exif extension. A specially-crafted image file could cause
the PHP interpreter to crash when a PHP script tries to extract
Exchangeable image file format (Exif) metadata from the image file.
(CVE-2011-0708)

An integer overflow flaw was found in the PHP calendar extension. A remote
attacker able to make a PHP script call SdnToJulian() with a large value
could cause the PHP interpreter to crash. (CVE-2011-1466)

A bug in the PHP Streams component caused the PHP interpreter to crash if
an FTP wrapper connection was made through an HTTP proxy. A remote attacker
could possibly trigger this issue if a PHP script accepted an untrusted URL
to connect to. (CVE-2011-1469)

An off-by-one flaw was found in PHP. If an attacker uploaded a file with a
specially-crafted file name it could cause a PHP script to attempt to write
a file to the root (/) directory. By default, PHP runs as the apache
user, preventing it from writing to the root directory. (CVE-2011-2202)

Red Hat would like to thank oCERT for reporting CVE-2011-4885. oCERT
acknowledges Julian Wälde and Alexander Klink as the original reporters of
CVE-2011-4885.

All php users should upgrade to these updated packages, which contain
backported patches to resolve these issues. After installing the updated
packages, the httpd daemon must be restarted for the update to take effect.

Solution:
Please note that this update is available via
Red Hat Network. To use Red Hat Network, launch the Red
Hat Update Agent with the following command: up2date
