Davfs2, a filesystem client for WebDAV, calls the function system() insecurely while is setuid root. This might allow a privilege escalation.

For the oldstable distribution (squeeze), this problem has been fixed in version 1.4.6-1.1+squeeze1. For the stable distribution (wheezy), this problem has been fixed in version 1.4.6-1.1+deb7u1. For the testing distribution (jessie), this problem has been fixed in version 1.4.7-3. For the unstable distribution (sid), this problem has been fixed in version 1.4.7-3. We recommend that you upgrade your davfs2 packages.

Web Distributed Authoring and Versioning (WebDAV), an extension to the HTTP-protocol, allows authoring of resources on a remote web server. davfs2 provides the ability to access such resources like a typical filesystem, allowing for use by standard applications with no built-in support for WebDAV.
