CVE-2011-0064
EPSS 3.1%pango1.0 - NULL pointer dereference
Published: 3/7/2011Modified: 4/28/2026
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.
Affected packages (2)
