In some scenario, an attacker could use this vulnerability to trick an user an execute arbitrary code on the platform with the privileges of that user.

For the oldstable distribution (buster), this problem has been fixed in version 0.12.4-1+deb10u1.

For the stable distribution (bullseye), this problem has been fixed in version 4.16.0-1+deb11u1.

We recommend that you upgrade your exo packages.

For the detailed security status of exo please refer to its security tracker page at: [link moved to references]");
