Hi, Even with the patch for CVE-2015-3258 in version 1.0.70 it was possible to trigger an integer overflow leading to a heap-based buffer overflow using the same vector (specially crafted line sizes). The integer overflow has been assigned CVE-2015-3279 and is fixed in version 1.0.71. Apart from that, the patch also hardens against possible crashes due to missing calloc() success checks. Patch: http://bzr.linuxfoundation.org/loggerhead/openprinting/cups-filters/revision/7365 Red Hat bug: https://bugzilla.redhat.com/show_bug.cgi?id=1238990 Thanks, -- Stefan Cornelius / Red Hat Product Security
