There is no fixed version for Centos:8 php-odbc.

NVD Description

Note: Versions mentioned in the description apply only to the upstream php-odbc package and not the php-odbc package as distributed by Centos. See How to fix? for Centos:8 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.
