|Bugzilla:||678563: CVE-2011-0064 pango: missing memory reallocation failure checking in hb_buffer_ensure|
The MITRE CVE dictionary describes this issue as:
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.
This issue did not affect the versions of qt shipped with Red Hat Enterprise Linux 4, 5 and 6.
