Description

In KDE KCoreAddons before 6.25, KShell::quoteArgs is intended to safely quote arguments so that they can be passed to a shell command. This parsing does not adequately handle metacharacters, leading to an escape from the shell. All applications relying on this method in a security-critical path to handle user input are affected and could be exploited. In particular, because sendInput() sends a string to a terminal, a control character such as \x01 can be used during injection.
