Name of the Vulnerable Software and Affected Versions DISCOUNT version 2.2.3a

Description The issue allows remote attackers to cause a denial of service, specifically a heap-based buffer over-read, via a crafted file. This is demonstrated by the mkd2html function.

Recommendations For version 2.2.3a, consider restricting the use of the mkd trim line function in mkdio.c until a patch is available. As a temporary workaround, avoid using crafted files that may trigger the heap-based buffer over-read. At the moment, there is no information about a newer version that contains a fix for this issue.
