------------------------------------------------------------------------- Debian LTS Advisory DLA-2733-1 debian-lts@lists.debian.org https://www.debian.org/lts/security/ Markus Koschany August 05, 2021 https://wiki.debian.org/LTS ------------------------------------------------------------------------- Package : tomcat8 Version : 8.5.54-0+deb9u7 CVE ID : CVE-2021-30640 CVE-2021-33037 Debian Bug : 991046 991046 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 9 stretch, these problems have been fixed in version 8.5.54-0+deb9u7. We recommend that you upgrade your tomcat8 packages.
