CVE-2011-0064: Gnome Pango
Medium severity, CVSS 6.8. EPSS: 3.3% chance of exploitation in the next 30 days.
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.
