Ubuntu 20.04 LTS / 22.04 LTS : kitty vulnerabilities (USN-5659-1)

critical Nessus Plugin ID 165718

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 20.04 LTS / 22.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5659-1 advisory.

 - The Graphics Protocol feature in graphics.c in kitty before 0.19.3 allows remote attackers to execute arbitrary code because a filename containing special characters can be included in an error message.
 (CVE-2020-35605)

 - 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. (CVE-2022-41322)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected kitty and / or kitty-terminfo packages.
