Name of the Vulnerable Software and Affected Versions loolforkit (affected versions not specified)

Description The issue arises from a flawed check in the "loolforkit" program, which is supposed to be run by a special, non-privileged "lool" user. This check is intended to prevent the program from running with privileges if it's not invoked by the "lool" user. However, in the vulnerable version, this check is incorrect, allowing a normal user to start "loolforkit" and potentially gain local root privileges.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
