Descriptions
Buffer overflow in rn5auth.dll in RealNetworks Helix Server and Helix Mobile Server 14.x before 14.3.x allows remote attackers to execute arbitrary code via crafted authentication credentials.
Desbordamiento de búfer en rn5auth.dll en RealNetworks Helix Server y Helix Mobile Server v14.x anteriores a v14.3.x permite a atacantes remotos ejecutar código a través de credenciales de autenticación manipuladas.
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Real Helix Server. Authentication is not required to exploit this vulnerability.
The specific flaw exists within rn4auth.dll, which is responsible for parsing authentication credentials. When the GetNameValuePair() function calls strcpy, there is an unbounded copy into a stack buffer, which can lead to stack memory corruption. An attacker can leverage this vulnerability to execute code under the context of the process.
