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.
