therefore, affected by a remote code execution vulnerability. By persuading a victim to open specially-crafted content,
an attacker could exploit this vulnerability to execute arbitrary code on the system with privileges of the victim.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
