Debian Security Advisory                             security@debian.org

Package        : cupsys

Problem type   : remote misuse of printer

Debian-specific: no



Mandrake has recently released a security advisory against CUPS

raising two issues:



 1. CUPS sends broadcast packets, which can keep dial-on-demand lines

    up and otherwise irritate network administrators.



 2. CUPS has a rather vague problem to the effect of "everyone on the

    Internet can get to your printers".



The first problem is not a problem either in Debian's potato (2.2) or

woody (unstable).  Our cupsys packages are shipped with browsing

turned off by default.



The second problem has to do with CUPS's configuration.  CUPS does

access control in a similar way to Apache, and is configured by

default in a similar way to Apache.  This isn't terribly appropriate

in the case of allowing people to attach to printers.  Administrative

tasks still aren't allowed, but Internet users could (for example) run

all the paper out of your printer.  Debian as shipped in potato and

woody is vulnurable to this latter problem.



The fix is simply to configure access control to reflect your real

wishes, which is done in /etc/cups/cupsd.conf.  This can be done with

the current packages (in both potato and woody).



This has been fixed in version 1.0.4-8 (or 1.1.4-2 for unstable) and

we recommend that you upgrade your cupsys packages immediately.
