Several security vulnerabilities have been discovered in the Tomcat servlet and JSP engine.
CVE-2021-30640
A vulnerability in the JNDI Realm of Apache Tomcat allows an attacker to
authenticate using variations of a valid user name and/or to bypass some of
the protection provided by the LockOut Realm.
CVE-2021-33037
Apache Tomcat did not correctly parse the HTTP transfer-encoding request
header in some circumstances leading to the possibility to request
smuggling when used with a reverse proxy. Specifically: - Tomcat
incorrectly ignored the transfer encoding header if the client declared it
would only accept an HTTP/1.0 response; - Tomcat honoured the identify
encoding; and - Tomcat did not ensure that, if present, the chunked
encoding was the final encoding.
For Debian 8 jessie, these problems have been fixed in version 8.0.14-1+deb8u22.
We recommend that you upgrade your tomcat8 packages.
