DESCRIPTION
PHP[1] is a very popular scripting language used by web servers to
offer dynamic content.
Stefan Esser noted[2] a vulnerability[3] in php code so that a remote
attacker could force php to hit memory_limit in unsafe places which
would lead to a possible execution of arbitrary code.
He also found[4] out that the strip_tags() function, often used as a
validator for user input, could allow tags containing the null char.
This announcement also fixes the misinstalation of the CLI interface
instead of the CGI one. Thanks to Willian Marcelo Piovezan for the
report[5].
SOLUTION
It is recommended that all PHP users upgrade their packages.
IMPORTANT
If PHP is being used as an Apache module, the web server has to be
restarted after the upgrade if it was already running. To do so,
please run, as
root:
# service httpd stop
(wait a few seconds and check with "ps ax|grep httpd" if there are
any httpd
processes running. On a busy webserver this could take a little
longer.)
ADDITIONAL INSTRUCTIONS
The apt tool can be used to perform RPM packages upgrades:
- run: apt-get update
- after that, execute: apt-get upgrade
