Description

FreeType contains an overflow condition in src/bdf/bdflib.c. The issue is triggered as user-supplied input is not properly validated when adding properties. With a specially crafted Bitmap Distribution Format (BDF) font file, a context-dependent attacker can cause a heap-based buffer overflow, resulting in a denial of service or potentially execution of arbitrary code.
