How to fix?

Upgrade SLES:15.0 php7-wddx to version 7.2.5-4.3.1 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.

exif_read_from_impl in ext/exif/exif.c in PHP 7.2.x through 7.2.7 allows attackers to trigger a use-after-free (in exif_read_from_file) because it closes a stream that it is not responsible for closing. The vulnerable code is reachable through the PHP exif_read_data function.
