Joomla Update Blog

Most if not all issues with Joomla installations have to do with not timely update your Joomla version, below you will find the standard Security RSS feed of Joomla; these are only the updates you may need for the CORE of the software, not for any additional plugins you may have installed. It is important to always check your CORE Joomla files but do not forget your added components or plugins. Also always remove any unused components, themes or plugins for any installation (Joomla or any other software product).

In order to intercept file invocations like file_exists or stat on compromised Phar archives the base name has to be determined and checked before allowing to be handled by PHP Phar stream handling. The used implementation however is vulnerable to path traversal leading to scenarios where the Phar archive to be assessed is not the actual (compromised) file.\r\nAffected Installs\r\nJoomla!
