Multiple security vulnerabilities have been found in OpenEXR, command-line
tools and a library for the OpenEXR image format. Buffer overflows or
out-of-bound reads could lead to a denial of service (application crash) if
a malformed image file is processed.

For Debian 10 buster, these problems have been fixed in version
2.2.1-4.1+deb10u2.

We recommend that you upgrade your openexr packages.
