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 security tracker page at:

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
