tomcat vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 25.04
- Ubuntu 24.10
- Ubuntu 24.04 LTS
- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS
Summary:
Several security issues were fixed in tomcat8, tomcat9, tomcat10.
Software Description:
- tomcat9: Servlet and JSP engine
- tomcat10: Servlet and JSP engine
- tomcat8: Servlet and JSP engine
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.
