Multiple vulnerabilities have been discovered in openjpeg2, the open-source JPEG 2000 codec, which could result in denial of service or the execution of arbitrary code when opening a malformed image.
For the stable distribution (buster), these problems have been fixed in version 2.3.0-2+deb10u2.
We recommend that you upgrade your openjpeg2 packages.
