medium Nessus Plugin ID 117503

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

Several heap buffer overflows were found in discount, an implementation of the Markdown markup language, that could be triggered with specially crafted Markdown data and would cause discount to read past the end of internal buffers.

Solution

Upgrade the discount packages.

For the stable distribution (stretch), these problems have been fixed in version 2.2.2-1+deb9u1.
