So many vulnerabilities affecting the lpd (line printer daemon) have come to light in recent months that CERT/CC has issued a compendium advisory urging all users and admins to review their system configurations and patch status.

"All of these vulnerabilities can be exploited remotely. In most cases, they allow an intruder to execute arbitrary code with the privileges of the lpd server," CERT explains.

Affected systems include:

--BSDi BSD/OS Version 4.1 and earlier
--Debian GNU/Linux 2.1 and 2.1r4
--FreeBSD All released versions FreeBSD 4.x, 3.x, FreeBSD 4.3-STABLE, 3.5.1-STABLE prior to the correction date
--Hewlett-Packard HP9000 Series 700/800 running HP-UX releases 10.01, 10.10, 10.20, 11.00, and 11.11
--IBM AIX Versions 4.3 and AIX 5.1
--Mandrake Linux Versions 6.0, 6.1, 7.0, 7.1
--NetBSD 1.5.2 and earlier
--OpenBSD Version 2.9 and earlier
--Red Hat Linux 6.0 all architectures

--Sun Solaris 8 and earlier
--SuSE Linux Versions 6.1, 6.2, 6.3, 6.4, 7.0, 7.1, 7.2

Quite a list -- no doubt soon to be framed on Bill Gates' office wall. ®
