Local Denial of Service in Jami

Vulnerability Description

The "nickname" field within Savoir-faire Linux's Jami application is susceptible to a failed state when a user inserts special characters into the field. When present, these special characters, make it so the application cannot create the signature for the user and results in a local denial of service to the application.
