    Package        : kitty
    Version        : 0.19.3-1+deb11u1
    CVE ID         : CVE-2022-41322
    Debian Bug     : 1020582

    A vulnerability has been found in kitty, a fast, featureful, GPU based
    terminal emulator, which possible allows arbitrary code execution.

    CVE-2022-41322

        In Kitty before 0.26.2, insufficient validation in the desktop
        notification escape sequence can lead to arbitrary code execution. The
        user must display attacker-controlled content in the terminal, then
        click on a notification popup.

    For Debian 11 bullseye, this problem has been fixed in version
    0.19.3-1+deb11u1.

    We recommend that you upgrade your kitty packages.
