RealityServer Web Services is prone to a remote denial-of-service vulnerability caused by a NULL pointer dereference.
|
||
|
||
Attackers can exploit this issue to cause the server to dereference an invalid memory location, resulting in a denial-of-service condition. Due to the nature of this issue arbitrary code-execution maybe possible; however this has not been confirmed.
|
||
|
||
RealityServer Web Services 3.1.1 build 144525.5057 is vulnerable; other versions may also be affected.
