More information:

Several heap-based buffer over-reads were found in discount, an implementation of the Markdown markup language in C, that allowed remote attackers to cause a denial-of-service via specially crafted files.

For Debian 8 Jessie, these problems have been fixed in version 2.1.7-1+deb8u1.

We recommend that you upgrade your discount packages.
