"An update for exiv2 is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security
impact of Low. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link (s) in the References section.

and manipulate image metadata such as EXIF, LPTC, and JPEG comments.

The following packages have been upgraded to a later upstream version:
exiv2 (0.27.0). (BZ#1652637)
