Synopsis
The remote Debian host is missing a security update.Description
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.
