Descriptions

Stack-based buffer overflow in the PlayMacro function in ObjectXMacro.ObjectXMacro in WdMacCtl.ocx in Micro Focus Rumba 9.x before 9.3 HF 11997 and 9.4.x before 9.4 HF 12815 allows remote attackers to execute arbitrary code via a long MacroName argument. NOTE: some references mention CVE-2016-5226 but that is not a correct ID for any Rumba vulnerability.

NOTA: algunas referencias mencionan CVE-2016-5226 pero ese no es el ID corrector para ninguna vulnerabilidad de Rumba.

Micro Focus Rumba versions 9.3 and below suffer from an active-x stack buffer overflow vulnerability.
