CVE-2011-0064

The hb_buffer_ensure function in hb-buffer.c in HarfBuzz, as used in Pango
1.28.3, Firefox, and other products, does not verify that memory
reallocations succeed, which allows remote attackers to cause a denial of
service (NULL pointer dereference and application crash) or possibly
execute arbitrary code via crafted OpenType font data that triggers use of
an incorrect index.
