The scope of this CVE does not include the "nothing that guarantees that r->bpp is non-zero" observation the "Feb 1, 2015" comment. > since compression isn't used between filters and since we use > sandboxing whenever possible, it is unlikely that this will be > exploitable This isn't directly relevant to whether a CVE should exist, but http://cups.org/documentation.php/doc-2.0/man-cups-files.conf.html mentions 'Specifies the level of security sandboxing that is applied to print filters, backends, and other child processes of the scheduler. The default is "strict". This directive is currently only used/supported on OS X.' Apparently some online discussions of CUPS include third-party recommendations to disable sandboxing. - -- CVE assignment team, MITRE CVE Numbering Authority M/S M300 202 Burlington Road, Bedford, MA 01730 USA [ PGP key available through http://cve.mitre.org/cve/request_id.html ] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.14 (SunOS) iQEcBAEBAgAGBQJU3NpOAAoJEKllVAevmvms+zAH/RzYRlzOX/Mm66NVZE5Svr8j XDMba6Yls6khp4rhXsUtIyjwRt+sjag5v+QWiDBv1ZEGJwD72MalgUQwYHOy0AGj fmqu6kiRd2rFU/c95IHj4N5H3NXvsrspWbmo8/p7cBTl5i/zDRCK8rG15SoTEHu/ CUNR3KPeuVawwUzH4dFlWAQkTUP5DL20xPFcJb+kXr/vu7uwxedamjBH8twGVD6v /Pe8ktGAmfYEuj4tbcsj4kyU30U7wCzIAw5uZ2DvtuaP8uLyWeBqYAaWyz/754uC dFbGodPxsMmltshpDPHsRdMzjN5kc6fHAYJzW8r/sqsvR2xNlBV+u1J4Vw06EH4= =2glT -----END PGP SIGNATURE-----
