Vulnerability Assessment Summary
w3m: Format string vulnerability

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200701-06

load a specially crafted X.509 SSL certificate containing "%n" or other
format string specifiers, possibly resulting in the execution of
arbitrary code with the rights of the user running w3m.

Workaround

There is no known workaround at this time.
