Updated tomcat packages fix security vulnerabilities

Publication date: 28 Jan 2020
Type: security
Affected Mageia releases : 7
CVE: CVE-2019-12418 , CVE-2019-17563


When Apache Tomcat 9.0.0.M1 to 9.0.28, 8.5.0 to 8.5.47, 7.0.0 and 7.0.97
is configured with the JMX Remote Lifecycle Listener, a local attacker
without access to the Tomcat process or configuration files is able to
manipulate the RMI registry to perform a man-in-the-middle attack to
capture user names and passwords used to access the JMX interface. The
attacker can then use these credentials to access the JMX interface and
gain complete control over the Tomcat instance. (CVE-2019-12418)

When using FORM authentication with Apache Tomcat 9.0.0.M1 to 9.0.29,
8.5.0 to 8.5.49 and 7.0.0 to 7.0.98 there was a narrow window where an
attacker could perform a session fixation attack. The window was
considered too narrow for an exploit to be practical but, erring on the
side of caution, this issue has been treated as a security
vulnerability. (CVE-2019-17563)
