NVD Description
Note: Versions mentioned in the description apply only to the upstream php73-common package and not the php73-common package as distributed by Amazon-Linux.
See How to fix? for Amazon-Linux:2018.03 relevant fixed versions and status.
An issue was discovered in PHP before 7.1.27, 7.2.x before 7.2.16, and 7.3.x before 7.3.3. Due to the way rename() across filesystems is implemented, it is possible that file being renamed is briefly available with wrong permissions while the rename is ongoing, thus enabling unauthorized users to access the data.
