Local privilege escalation in UNIX Fourth Research Edition (v4) su command allows any local user to gain root via a fixed 100-byte buffer overflow in the 'password' variable. EPSS is negligible (0.01%) and no public exploit identified at time of analysis; practical relevance is minimal since UNIX v4 survives only in a handful of historical lab and museum environments. Of historical and academic interest rather than operational risk.
