Remediation
Red Hat statement
This issue affects the libsoup packages as shipped with Red Hat Enterprise Linux 7. However, these packages have been compiled with additional security mitigation techniques ("stack smashing protection"), which makes exploitation significantly harder. Thus, in most cases an exploitation attempt should be mitigated to a mere crash. However, successful exploitation to execute arbitrary code can't be ruled out entirely.
