Descriptions

Integer signedness error in the authentication functionality in librpc.dll in the Informix Storage Manager (ISM) Portmapper service (aka portmap.exe), as used in IBM Informix Dynamic Server (IDS) 10.x before 10.00.TC9 and 11.x before 11.10.TC3 and EMC Legato NetWorker, allows remote attackers to execute arbitrary code via a crafted parameter size that triggers a stack-based buffer overflow.

Error de entero sin signo en la funcionalidad de autenticación en librpc.dll en Informix Storage Manager (ISM) Portmapper service (aka portmap.exe), tal y como se utiliza en IBM Informix Dynamic Server (IDS) v10.x anteriores a la v10.00.TC9 y v11.x anteriores a v11.10.TC3 y EMC Legato NetWorker, permite a atacantes remotos ejecutar código arbitrario a través de un parámetro manipulado en tamaño que inicia un desbordamiento de búfer basado en la pila.

This vulnerability allows attackers to execute arbitrary code on vulnerable installations of both IBM Informix Dynamic Server and EMC Legato Networker. User interaction is not required to exploit this vulnerability.
The specific flaw exists within the RPC protocol parsing library, librpc.dll, utilized by the ISM Portmapper service (portmap.exe) bound by default to TCP port 36890. During authentication, a lack of a proper signedness check on a supplied parameter size can result in exploitable stack based buffer overflow leading to arbitrary code execution under the context of the SYSTEM user.
