RCE (0-day) en GhostScript-9.50

Escribir sobre una vulnerabilidad en ActiveX en 2021 no deja de ser curioso. Microsoft se ha visto obligado a publicar un aviso porque los atacantes ya la están aprovechando. Se explota a través de Office. El documento tiene la habilidad de usar MSHTML (algo del tipo mshtml:// que invoca al motor de Internet Explorer en Office) a través de un objeto OLE para ver contenido web y a partir de aquí lanza un ActiveX, que no es más que una funcionalidad ya antigua de Microsoft para ejecutar código en el contexto del navegador, pero que se mantiene internamente integrado en muchos aspectos del sistema operativo. Por supuesto la ejecución ocurre de forma transparente. El fichero HTML que trae el documento es un .CPL especialmente manipulado que finalmente ejecuta una DLL.

Se espera que puedan publicar un parche para la semana que viene. Mientras, la recomendación es desactivar ActiveX en todas las zonas de Internet Explorer.

Cisco IOS XR Software IP Service Level Agreements and Two-Way Active Measurement Protocol Denial of Service Vulnerability
https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ipsla-ZA3SRrpP?vs_f=Cisco%20Security%20Advisory&vs_cat=Security%20Intelligence&vs_type=RSS&vs_p=Cisco%20IOS%20XR%20Software%20IP%20Service%20Level%20Agreements%20%20and%20Two-Way%20Active%20Measurement%20Protocol%20Denial%20of%20Service%20Vulnerability&vs_k=1

A vulnerability in the IP Service Level Agreements (IP SLA) responder and Two-Way Active Measurement Protocol (TWAMP) features of Cisco IOS XR Software could allow an unauthenticated, remote attacker to cause device packet memory to become exhausted or cause the IP SLA process to crash, resulting in a denial of service (DoS) condition.
This vulnerability exists because socket creation failures are mishandled during the IP SLA and TWAMP processes. An attacker could exploit this vulnerability by sending specific IP SLA or TWAMP packets to an affected device. A successful exploit could allow the attacker to exhaust the packet memory, which will impact other processes, such as routing protocols, or crash the IP SLA process.
Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
This advisory is available at the following link:
https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ipsla-ZA3SRrpP

This advisory is part of the September 2021 release of the Cisco IOS XR Software Security Advisory Bundled Publication. For a complete list of the advisories and links to them, see Cisco Event Response: September 2021 Cisco IOS XR Software Security Advisory Bundled Publication (https://tools.cisco.com/security/center/viewErp.x?alertId=ERP-74637).
