If the user added a security exception for an invalid TLS certificate, opened an ongoing TLS connection with a server that used that certificate, and then deleted the exception, Firefox would have kept the connection alive, making it seem like the certificate was still trusted. This vulnerability affects Firefox < 107.
Si el usuario agregó una excepción de seguridad para un certificado TLS no válido, abrió una conexión TLS en curso con un servidor que usaba ese certificado y luego eliminó la excepción, Firefox habría mantenido viva la conexión, haciendo que pareciera que el certificado todavía era confiable. Esta vulnerabilidad afecta a Firefox < 107.
Multiple security issues were discovered in Firefox. If a user were tricked into opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service, spoof the contents of the addressbar, bypass security restrictions, cross-site tracing or execute arbitrary code.
