Some Government of Canada websites have been temporarily taken offline as a precaution to protect government systems and Canadians' information, following guidance from the Canadian Centre for Cyber Security.

This is in response to a vulnerability identified in PHP, software…
Solomon said the government is taking this situation “extremely seriously” and that tech teams are working on patches before restoring the affected websites.
However, he did not identify which websites were offline or how long they would be out of service.
Critical vulnerabilities affecting PHP
The cyber security agency said in an alert to IT professionals and managers that it was aware of critical vulnerabilities affecting multiple versions of PHP, a website scripting language.
The agency said a “successful exploitation could allow an unauthenticated threat actor to execute arbitrary code on an affected system” and that internet-facing PHP servers and applications are at heightened risk. Security updates were released to address the vulnerabilities.

“Organizations should identify affected systems and apply the appropriate updates immediately,” the government agency said, adding there is no active exploitation that has been identified but that could change quickly.
Solomon advised organizations using PHP to apply the latest security updates as soon as possible and to follow the Canadian Centre for Cyber Security for the latest updates.
