Summary

Null byte termination in hostnames

Details

In PHP versions:8.1. before 8.1.33, 8.2. before 8.2.29, 8.3. before 8.3.23, 8.4. before 8.4.10 some functions like fsockopen() lack validation that the hostname supplied does not contain null characters. This may lead to other functions like parse_url() treat the hostname in different way, thus opening way to security problems if the user code implements access checks before access using such functions.
