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 avoiding the use of the isfootnote function in markdown.c until a patch is available. As a temporary workaround, restrict the processing of crafted files to minimize the risk of exploitation.
