Descriptions

The project received a report that all versions of Apache OpenOffice through 4.1.8 can open non-http(s) hyperlinks. The problem has existed since about 2006 and the issue is also in 4.1.9. If the link is specifically crafted this could lead to untrusted code execution. It is always best practice to be careful opening documents from unknown and unverified sources. The mitigation in Apache OpenOffice 4.1.10 (unreleased) assures that a security warning is displayed giving the user the option of continuing to open the hyperlink.

El proyecto recibió un reporte de que todas las versiones de Apache OpenOffice versiones hasta 4.1.8, pueden abrir hipervínculos que no sean http. El problema se presenta desde aproximadamente 2006 y el problema también se encuentra en versión 4.1.9. Si el enlace está diseñado específicamente, esto podría conllevar a una ejecución de un código no confiable. Siempre es una buena práctica tener cuidado al abrir documentos de fuentes desconocidas y no comprobadas. La mitigación en Apache OpenOffice versión 4.1.10 (unreleased) asegura que una alerta de seguridad es mostrada dándole al usuario la opción de continuar abriendo el hipervínculo
