tag_summary = "1. RealNetworks Helix Server is prone to a remote code-execution
vulnerability because of a format-string error.

Successful exploits can allow the attacker to execute arbitrary code
in the context of the application. Failed exploit attempts will result
in a denial-of-service condition.

2. RealNetworks Helix Server and Helix Mobile Server are prone to a
remote stack-based buffer-overflow vulnerability due to a failure to
properly bounds-check user-supplied data.

An attacker can exploit this issue to execute arbitrary code in the
context of the affected application. Failed exploit attempts will
result in a denial-of-service condition.";
