How to fix?

There is no fixed version for RHEL:7 gpgme.

NVD Description

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

Multiple heap-based buffer overflows in the status_handler function in (1) engine-gpgsm.c and (2) engine-uiserver.c in GPGME before 1.5.1 allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via vectors related to "different line lengths in a specific order."
