Debian Bug : 1139898
Multiple security issues were discovered in kitty, a GPU based terminal
emulator, which may result in the execution of arbitrary code, command
injection into the shell running in the terminal, or the overwriting of
arbitrary files, if untrusted content is displayed in a terminal window.
For the stable distribution (trixie), these problems have been fixed in
version 0.41.1-2+deb13u2.
We recommend that you upgrade your kitty packages.
