When computing the size of a memory region, integer wraparound is not taken into account, resulting in a heap allocation that is smaller than expected and which is subsequently filled with arbitrary decompressed data: <https://bugzilla.redhat.com/show_bug.cgi?id=1085663> We have assigned CVE-2014-0172 to this issue. -- Florian Weimer / Red Hat Product Security Team
