Description:
Some vulnerabilities have been reported in PHP, where some have unknown impacts and another can be exploited by malicious people to bypass certain security restrictions, or conduct cross-site scripting and HTTP response smuggling attacks.

1) An offset/length parameter validation error exists in the "substr_compare()" function.

2) An error exists in the handling of certain characters in session names, which can be exploited to conduct cross-site scripting or HTTP response splitting attacks.
