MGASA-2021-0485 - Updated tomcat packages fix security vulnerability

Publication date: 23 Oct 2021
URL: https://advisories.mageia.org/MGASA-2021-0485.html
Type: security
Affected Mageia releases: 8
CVE: CVE-2021-30640,
     CVE-2021-33037,
     CVE-2021-41079,
     CVE-2021-42340

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-2021-30640)

Apache Tomcat 10.0.0-M1 to 10.0.6, 9.0.0.M1 to 9.0.46 and 8.5.0 to 8.5.66
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. (CVE-2021-33037)

Apache Tomcat 8.5.0 to 8.5.63, 9.0.0-M1 to 9.0.43 and 10.0.0-M1 to 10.0.2
did not properly validate incoming TLS packets. When Tomcat was configured
to use NIO+OpenSSL or NIO2+OpenSSL for TLS, a specially crafted packet
could be used to trigger an infinite loop resulting in a denial of service.
(CVE-2021-41079)

The fix for bug 63362 present in Apache Tomcat 10.1.0-M1 to 10.1.0-M5,
10.0.0-M1 to 10.0.11, 9.0.40 to 9.0.53 and 8.5.60 to 8.5.71 introduced a
memory leak. The object introduced to collect metrics for HTTP upgrade
connections was not released for WebSocket connections once the
connection was closed. This created a memory leak that, over time, could
lead to a denial of service via an OutOfMemoryError. (CVE-2021-42340)
