Name of the Vulnerable Software and Affected Versions FontForge version 20161012

Description The issue is related to a stack-based buffer overflow in the addnibble function, located in parsettf.c, which can be triggered by a crafted otf file. This can result in a denial of service (DoS) or potentially allow for code execution.
