6.8 MEDIUM — AV:N/AC:M/Au:N/C:P/I:P/A:P

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 configurations

• gnome pango 1.28.3 • mozilla firefox
