NVD Description
Note: Versions mentioned in the description apply only to the upstream php7.4 package and not the php7.4 package as distributed by Ubuntu.
See How to fix? for Ubuntu:20.04 relevant fixed versions and status.
The zend_string_extend function in Zend/zend_string.h in PHP through 7.1.5 does not prevent changes to string objects that result in a negative length, which allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact by leveraging a script's use of .= with a long string.
