Package        : kitty
CVE ID         : CVE-2020-35605

Stephane Chauveau discovered that the graphics protocol implementation in
Kitty, a GPU-based terminal emulator, did not sanitise a filename when
returning an error message, which could result in the execution of
arbitrary shell commands when displaying a file with cat.

For the stable distribution (buster), this problem has been fixed in
version 0.13.3-1+deb10u1.

We recommend that you upgrade your kitty packages.

For the detailed security status of kitty please refer to
its security tracker page at:
