CVE-2011-0064 Information

Description

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.
