  Workaround :

    There is no known work around at this time.

It was discovered that libwmf did not correctly process certain WMF (Windows Metafiles) with embedded BMP images. By tricking a victim into opening a specially crafted WMF file in an application using libwmf, a remote attacker could possibly use this flaw to execute arbitrary code with the privileges of the user running the application. (CVE-2015-0848 , CVE-2015-4588)

It was discovered that libwmf did not properly process certain WMF files.
