MGASA-2018-0479 - Updated tomcat packages fix security vulnerabilities

Publication date: 09 Dec 2018
URL: https://advisories.mageia.org/MGASA-2018-0479.html
Type: security
Affected Mageia releases: 6
CVE: CVE-2018-1336,
     CVE-2018-8014,
     CVE-2018-8034,
     CVE-2018-11784

An improper handing of overflow in the UTF-8 decoder with supplementary
characters can lead to an infinite loop in the decoder causing a Denial
of Service (CVE-2018-1336).

The defaults settings for the CORS filter are insecure and enable
supportsCredentials for all origins. It is expected that users of the
CORS filter will have configured it appropriately for their environment
rather than using it in the default configuration. Therefore, it is
expected that most users will not be impacted by this issue
(CVE-2018-8014).

The host name verification when using TLS with the WebSocket client was
missing. It is now enabled by default (CVE-2018-8034).

When the default servlet returned a redirect to a directory (e.g.
redirecting to /foo/ when the user requested /foo) a specially crafted
URL could be used to cause the redirect to be generated to any URI of
the attackers choice (CVE-2018-11784).
