The remote host is affected by the vulnerability described in GLSA-201201-08 (FontForge: User-assisted execution of arbitrary code)
FontForge is vulnerable to an error when processing the 'CHARSET_REGISTRY' header in font files, which could cause a stack-based buffer overflow.
Impact :
A remote attacker could entice a user to open a specially crafted BDF file using FontForge font editor, possibly resulting in the remote execution of arbitrary code with the privileges of the FontForge process, or a Denial of Service (application crash).
Workaround :
There is no known workaround at this time.
