The PHP security team has issued an advance warning to administrators, telling them to prepare for emergency security updates scheduled for tomorrow. The updates are intended to fix two critical vulnerabilities, according to the team's notice.
The warning comes after information about the flaws leaked ahead of their planned disclosure. The team did not include technical details in the advisory, so the specific nature of the vulnerabilities and which versions are affected have not been made public yet.
Administrators should monitor the PHP release channels and be ready to apply the patches as soon as they land. Without further details, the safest course is to treat the upcoming update as urgent and plan maintenance windows accordingly.
