CVE-2024-2757

Publication date 29 April 2024

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

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.
