Описание
In PHP versions 7.2.x below 7.2.26, 7.3.x below 7.3.13 and 7.4.0, PHP bcmath extension functions on some systems, including Windows, can be tricked into reading beyond the allocated space by supplying it with string containing characters that are identified as numeric by the OS but aren't ASCII numbers. This can read to disclosure of the content of some memory locations.
Отчет
Any version of PHP as shipped with Red Hat Enterprise Linux are not affected. This flaw affected php running only on top of Windows Operating System, the bug itself is related to OS specific isdigit() function implementation.
