Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200608-28

applications making use of the sscanf() function, potentially resulting
in the execution of arbitrary code or the execution of scripted
contents in the context of the affected site.
