Date of Resolved Release
Multiple Security Vulnerabilities in Common UNIX Printing System (CUPS) May Allow a Remote User to Execute Arbitrary Code
The Common UNIX Printing System (CUPS) as shipped with OpenSolaris is impacted by multiple security vulnerabilities affecting the "imagetops", "texttops" and "hpgltops" filters. These vulnerabilities may allow a local or remote unprivileged user to execute arbitrary code with the privileges of the CUPS service (which usually runs as root).
These issues are described in the following documents:
CVE-2008-3639 at http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-3639
CVE-2008-3640 at http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-3640
CVE-2008-3641 at http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-3641
2. Contributing Factors
These issues can occur in the following releases:
1. Solaris 8, 9, and 10 are not impacted by these issues.
OpenSolaris distributions may include additional bug fixes above and beyond the build from which it was derived. The base build can be derived as follows:
$ uname -v2. These vulnerabilities only affect systems which are configured to use the CUPS software. This can be determined by checking the status of the appropriate SMF (smf(5)) service as in the following example:
% svcs application/cups/in-lpd3. A system is only vulnerable to a remote user while sharing a printer(s) on the network. To determine if a printer is being network shared, the following command can be run:
# grep Listen /etc/cups/cupsd.confIn the case above, it is listening only on the local interfaces.
There are no predictable symptoms that would indicate the described issues have been exploited.
There is no workaround for these issues. Please see the "Resolution" section below.
These issues are addressed in the following releases:
