Описание
In PHP versions 7.4.x below 7.4.28, 8.0.x below 8.0.16, and 8.1.x below 8.1.3, when using filter functions with FILTER_VALIDATE_FLOAT filter and min/max limits, if the filter fails, there is a possibility to trigger use of allocated memory after free, which can result it crashes, and potentially in overwrite of other memory chunks and RCE. This issue affects: code that uses FILTER_VALIDATE_FLOAT with min/max limits.
A flaw was found in PHP. The vulnerability occurs due to the malformed php_filter_float() function and leads to a use-after-free vulnerability. This flaw allows an attacker to inject a malicious file, leading to a crash or a Segmentation fault.
