How to fix?

There is no fixed version for Centos:7 fetchmail.

NVD Description

Note: Versions mentioned in the description apply only to the upstream fetchmail package and not the fetchmail package as distributed by Centos. See How to fix? for Centos:7 relevant fixed versions and status.

report_vbuild in report.c in Fetchmail before 6.4.20 sometimes omits initialization of the vsnprintf va_list argument, which might allow mail servers to cause a denial of service or possibly have unspecified other impact via long error messages. NOTE: it is unclear whether use of Fetchmail on any realistic platform results in an impact beyond an inconvenience to the client user.
