How to fix?

Upgrade SLES:15.0 php7-wddx to version 7.2.5-4.49.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream php7-wddx package and not the php7-wddx package as distributed by SLES. See How to fix? for SLES:15.0 relevant fixed versions and status.

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.
