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.
