Description

The payload length in a WebSocket frame was not correctly validated in Apache Tomcat 10.0.0-M1 to 10.0.0-M6, 9.0.0.M1 to 9.0.36, 8.5.0 to 8.5.56 and 7.0.27 to 7.0.104. Invalid payload lengths could trigger an infinite loop. Multiple requests with invalid payload lengths could lead to a denial of service.

Solution(s)

  • apache-tomcat-upgrade-7_0_105
  • apache-tomcat-upgrade-8_5_57
  • apache-tomcat-upgrade-9_0_37
