Debian 11 DSA-5299-1 Critical OpenEXR Buffer Overflow Risk

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 the stable distribution (bullseye), these problems have been fixed in
version 2.5.4-2+deb11u1.

We recommend that you upgrade your openexr packages.
