"It was found that the fix for CVE-2020-25712 in the Xorg X server,
addressed in DLA-2486-1, caused a regression in caribou, making it
crash whenever special (shifted) characters were entered.

For Debian 9 stretch, this problem has been fixed in version
0.4.21-1+deb9u1.

We recommend that you upgrade your caribou packages.

For the detailed security status of caribou please refer to its
