How to fix?

Upgrade Centos:8 libcurl-minimal to version 0:7.61.1-11.el8 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libcurl-minimal package and not the libcurl-minimal package as distributed by Centos. See How to fix? for Centos:8 relevant fixed versions and status.

libcurl versions from 7.34.0 to before 7.64.0 are vulnerable to a heap out-of-bounds read in the code handling the end-of-response for SMTP. If the buffer passed to smtp_endofresp() isn't NUL terminated and contains no character ending the parsed number, and len is set to 5, then the strtol() call reads beyond the allocated buffer. The read contents will not be returned to the caller.
