Vulnerability Assessment Summary
libwmf: Buffer overflow vulnerability

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200608-17

attacker could cause a heap-based buffer overflow and execute arbitrary
code with the permissions of the user running the application that uses
libwmf.

Workaround

There is no known workaround for this issue.
