Package : discount
Version : 2.1.7-1+deb8u1
CVE ID : CVE-2018-11468 CVE-2018-11503 CVE-2018-11504
CVE-2018-12495
Debian Bug : 901912

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.
