Debian -- Security Information Martin Schulze November 19, 2000 - ------------------------------------------------------------------------ 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. wget url will fetch the file for you dpkg -i file.deb will install the referenced file. Debian GNU/Linux 2.2 alias potato - --------------------------------- Potato was released for alpha, arm, i386, m68k, powerpc and sparc.
