More information:

It was discovered that FontForge, a font editor, did not correctly validate its input. An attacker could use this flaw by tricking a user into opening a maliciously crafted OpenType font file, thus causing a denial-of-service via application crash, or execution of arbitrary code.

For the oldstable distribution (jessie), these problems have been fixed in version 20120731.b-5+deb8u1.

For the stable distribution (stretch), these problems have been fixed in version 1:20161005~dfsg-4+deb9u1.

We recommend that you upgrade your fontforge packages.
