Descriptions

IBM Informix spatial 14.10 could allow a local user to execute commands as a privileged user due to an out of bounds write vulnerability. IBM X-Force ID: 189460.

IBM Informix spatial versión 14.10, podría permitir a un usuario local ejecutar comandos como usuario privilegiado debido a una vulnerabilidad de escritura fuera de límites. IBM X-Force ID: 189460

This vulnerability allows local attackers to escalate privileges on affected installations of IBM Informix. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.
The specific flaw exists within the spatial.bld module. When parsing SQL statements, the process does not properly validate user-supplied data, which can result in a write past the end of an allocated buffer. An attacker can leverage this vulnerability to escalate privileges and execute code in the context of the informix user.
