KTVision works with frame-grabber cards and KDE (Unix K Desktop Environment) to support TV video display on the PC screen.
KTVision is vulnerable to symbolic link attacks.
It is possible for an attacker to anticipate the expected name of a KTVision config file. A local attacker can then create a symbolic link with the anticipated filename pointing to files on the system writable by ktvision, (which is frequently suid root).
This could allow an attacker to overwrite any file on the filesystem, completely undermining the the security of the exploited system.
