COMMAND lpd SYSTEMS AFFECTED OpenBSD 3.0 and prior versions PROBLEM Todd C. Miller reported following, initialy found by Sebastian Krahmer of SuSE : A security issue exists with lpd (the line printer daemon) that may allow an attacker to create arbitrary new files in the root directory. Only machines with line printer access (ie: listed in either /etc/hosts.lpd or /etc/hosts.equiv) may be used to mount an attack and the attacker must have root access on the machine. OpenBSD does not start lpd in the default installation. SOLUTION A patch exists to fix the problem: For OpenBSD-2.9 (as well as OpenBSD-2.8): ftp://ftp.openbsd.org/pub/OpenBSD/patches/2.9/common/017_lpd.patch For OpenBSD-3.0 ftp://ftp.openbsd.org/pub/OpenBSD/patches/3.0/common/008_lpd.patch
