Technical details
The FreeBSD line printer daemon (lpd) is vulnerable to a classic buffer overflow. The flaw is triggered when the daemon processes a print request from a host with an excessively long DNS hostname, which exceeds the allocated buffer size in the stack. Because lpd often runs with elevated privileges to manage hardware and spooling, a remote, unauthenticated attacker can exploit this to overwrite the instruction pointer and execute arbitrary code with root privileges. This vulnerability is reachable over the network if the lpd service is exposed. Users should apply patches provided by the FreeBSD Project or upgrade to a version released after March 1997.
