How to fix?

There is no fixed version for RHEL:10 php53.

NVD Description

Note: Versions mentioned in the description apply only to the upstream php53 package and not the php53 package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

The utf8_decode function in PHP before 5.3.4 does not properly handle non-shortest form UTF-8 encoding and ill-formed subsequences in UTF-8 data, which makes it easier for remote attackers to bypass cross-site scripting (XSS) and SQL injection protection mechanisms via a crafted string.
