How to fix?

Upgrade Ubuntu:24.04 php8.3 to version 8.3.6-0maysync1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream php8.3 package and not the php8.3 package as distributed by Ubuntu. See How to fix? for Ubuntu:24.04 relevant fixed versions and status.

In PHP 8.3.* before 8.3.5, function mb_encode_mimeheader() runs endlessly for some inputs that contain long strings of non-space characters followed by a space. This could lead to a potential DoS attack if a hostile user sends data to an application that uses this function.
