Descriptions

A vulnerability in LibreOffice hyperlink processing allows an attacker to construct documents containing hyperlinks pointing to the location of an executable on the target users file system. If the hyperlink is activated by the victim the executable target is unconditionally launched. Under Windows and macOS when processing a hyperlink target explicitly activated by the user there was no judgment made on whether the target was an executable file, so such executable targets were launched unconditionally. This issue affects: All LibreOffice Windows and macOS versions prior to 6.1.6; LibreOffice Windows and macOS versions in the 6.2 series prior to 6.2.3.

Una vulnerabilidad en el procesamiento de hipervínculos de LibreOffice permite a un atacante construir documentos que contengan hipervínculos que apunten a la ubicación de un ejecutable en el sistema de archivos de los usuarios victimas. Si la víctima activa el hipervínculo, el objetivo ejecutable se inicia incondicionalmente. En Windows y macOS, al procesar un objetivo de hipervínculo activado explícitamente por el usuario, no se emitió un juicio sobre si el objetivo era un archivo ejecutable, por lo que dichos objetivos ejecutables fueron iniciados incondicionalmente. Este problema afecta: todas las versiones de Windows y macOS de LibreOffice versiones anteriores a 6.1.6; LibreOffice versiones de Windows y macOS en la serie 6.2 anterior a 6.2.3.
