A remote attacker can send a sequence of compressed HEADERS frames followed by RST_STREAM frames and perform a denial of service (DoS) attack, a.k.a. "Rapid Reset".

The vulnerability exists due to improper validation when parsing HTTP trailer headers. A remote attacker can send a specially crafted HTTP request to the server and smuggle arbitrary HTTP headers.
Successful exploitation of vulnerability may allow an attacker to poison HTTP cache and perform phishing attacks.
3) Resource management error (CVE-ID: CVE-2023-42795)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to improper management of internal resources within the application when recycling various internal objects. A remote attacker can force Tomcat to skip some parts of the recycling process leading to information leaking from the current request/response to the next.
