CVE-2019-9637 (opens in a new tab)How to fix?
Upgrade Ubuntu:14.04 php5 to version 5.5.9+dfsg-1ubuntu4.29 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream php5 package and not the php5 package as distributed by Ubuntu.
See How to fix? for Ubuntu:14.04 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.
