CVE-2024-23638

Squid is a caching proxy for the Web. Due to an expired pointer reference bug, Squid prior to version 6.6 is vulnerable to a Denial of Service attack against Cache Manager error responses. This problem allows a trusted client to perform Denial of Service when generating error pages for Client Manager reports. Squid older than 5.0.5 have not been tested and should be assumed to be vulnerable. All Squid-5.x up to and including 5.9 are vulnerable. All Squid-6.x up to and including 6.5 are vulnerable. This bug is fixed by Squid version 6.6. In addition, patches addressing this problem for the stable releases can be found in Squid's patch archives. As a workaround, prevent access to Cache Manager using Squid's main access control: `http_access deny manager`.

Summary
  • (es) Squid es un proxy de almacenamiento en caché para la Web. Debido a un error de referencia de puntero caducado, Squid anterior a la versión 6.6 es vulnerable a un ataque de denegación de servicio contra las respuestas de error del Administrador de Caché. Este problema permite que un cliente confiable realice una Denegación de Servicio al generar páginas de error para los informes de Client Manager. Los calamares mayores de 5.0.5 no han sido probados y se debe suponer que son vulnerables. Todos los Squid-5.x hasta 5.9 includa, son vulnerables. Todos los Squid-6.x hasta 6.5 includa, son vulnerables. Este error se solucionó con la versión 6.6 de Squid. Además, los parches que solucionan este problema para las versiones estables se pueden encontrar en los archivos de parches de Squid. Como workaround, evite el acceso al Administrador de caché utilizando el control de acceso principal de Squid: `http_access deny manager`.
