Summary:

Several security issues were fixed in PHP.

Software Description:
- php8.3: HTML-embedded scripting language interpreter
- php8.1: HTML-embedded scripting language interpreter
- php7.4: HTML-embedded scripting language interpreter

Details:

It was discovered that PHP incorrectly handled parsing multipart form data.
A remote attacker could possibly use this issue to inject payloads and
cause PHP to ignore legitimate data. (CVE-2024-8925)
