RHEL 6 : php-pear (RHSA-2011:1741)

Synopsis :

The remote Red Hat host is missing a security update.

Description :

An updated php-pear package that fixes one security issue and multiple
bugs is now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having low
security impact. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available from the
CVE link in the References section.

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.
