Package : discount
CVE ID : CVE-2018-11468 CVE-2018-11503 CVE-2018-11504 CVE-2018-12495
Debian Bug : 901912

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

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

We recommend that you upgrade your discount packages.

For the detailed security status of discount please refer to
its security tracker page at:
