Summary: tomcat vulnerabilities

Details: It was discovered that Tomcat did not include the secure attribute for session cookies when using the RemoteIpFilter with requests from a reverse proxy. An attacker could possibly use this issue to leak sensitive information. This issue was fixed for tomcat8 on Ubuntu 18.04 LTS and for tomcat9 on Ubuntu 24.04 LTS, Ubuntu 24.10, and Ubuntu 25.04. (CVE-2023-28708) It was discovered that Tomcat incorrectly recycled certain objects, which could lead to information leaking from one request to the next. An attacker could potentially use this issue to leak sensitive information. This issue was fixed for tomcat8 on Ubuntu 18.04 LTS and for tomcat9 on Ubuntu 24.04 LTS, Ubuntu 24.10, and Ubuntu 25.04. (CVE-2023-42795) It was discovered that Tomcat incorrectly handled HTTP trailer headers. A remote attacker could possibly use this issue to perform HTTP request smuggling. This issue was fixed for tomcat8 on Ubuntu 18.04 LTS and for tomcat9 on Ubuntu 24.04 LTS, Ubuntu 24.10, and Ubuntu 25.04. (CVE-2023-45648) It was discovered that Tomcat incorrectly handled incomplete POST requests, which could cause error responses to contain data from previous requests. An attacker could potentially use this issue to leak sensitive information. This issue was fixed for tomcat8 on Ubuntu 18.04 LTS and for tomcat9 on Ubuntu 18.04 LTS and Ubuntu 20.04 LTS. (CVE-2024-21733) It was discovered that Tomcat incorrectly handled socket cleanup, which could lead to websocket connections staying open. An attacker could possibly use this issue to cause a denial of service. This issue was fixed for tomcat8 on Ubuntu 18.04 LTS, tomcat9 on Ubuntu 24.04 LTS, Ubuntu 24.10, and Ubuntu 25.04, and for tomcat10 on Ubuntu 24.04 LTS. (CVE-2024-23672) It was discovered that Tomcat incorrectly handled HTTP/2 requests that exceeded configured header limits. An attacker could possibly use this issue to cause a denial of service. (CVE-2024-24549) It was discovered that Tomcat incorrectly handled some cases of excessive HTTP headers when processing HTTP/2 streams. This led to miscounting of active streams and incorrect timeout handling. An attacker could possibly use this issue to cause connections to remain open indefinitely, leading to a denial of service. This issue was fixed for tomcat9 on Ubuntu 22.04 LTS, Ubuntu 24.04 LTS, Ubuntu 24.10, and Ubuntu 25.04, and for tomcat10 on Ubuntu 24.04 LTS. (CVE-2024-34750) It was discovered that Tomcat incorrectly handled TLS handshake processes under certain configurations. An attacker could possibly use this issue to cause a denial of service. This issue was fixed for tomcat9 on Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, Ubuntu 24.04 LTS, Ubuntu 24.10, and Ubuntu 25.04, and for tomcat10 on Ubuntu 24.04 LTS. (CVE-2024-38286)
