A flaw was found in sblim-sfcb. A local, low-privileged attacker can exploit a race condition during privileged instance migration by manipulating a temporary file in the `/tmp` directory. By repeatedly recreating a symbolic link, the attacker can redirect privileged output to an arbitrary file. This can lead to privileged file corruption or a denial of service (DoS) on the system.
