Synopsis

The remote Debian host is missing a security-related update.

Description

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.

Solution

Upgrade the kitty packages.

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