Test ID:1.3.6.1.4.1.25623.1.0.870625
Category:Red Hat Local Security Checks
Title:RedHat Update for php-pear RHSA-2011:1741-03
Summary:The remote host is missing an update for the 'php-pear'; package(s) announced via the referenced advisory.
Description:Summary:
The remote host is missing an update for the 'php-pear'
package(s) announced via the referenced advisory.

Vulnerability Insight:
The php-pear package contains the PHP Extension and Application Repository
(PEAR), a framework and distribution system for reusable PHP components.

It was found that the 'pear' command created temporary files in an insecure
way when installing packages. A malicious, local user could use this flaw
to conduct a symbolic link attack, allowing them to overwrite the contents
of arbitrary files accessible to the victim running the 'pear install'
command. (CVE-2011-1072)

This update also fixes the following bugs:

* The php-pear package has been upgraded to version 1.9.4, which provides a
number of bug fixes over the previous version. (BZ#651897)

* Prior to this update, php-pear created a cache in the
'/var/cache/php-pear/' directory when attempting to list all packages. As a
consequence, php-pear failed to create or update the cache file as a
regular user without sufficient file permissions and could not list all
packages. With this update, php-pear no longer fails if writing to the
cache directory is not permitted. Now, all packages are listed as expected.
(BZ#747361)

All users of php-pear are advised to upgrade to this updated package, which
corrects these issues.

Affected Software/OS:
php-pear on Red Hat Enterprise Linux Server (v. 6),
Red Hat Enterprise Linux Workstation (v. 6)

Solution:
Please Install the Updated Packages.
