| Description: | Summary:
The remote host is missing an update for the 'tomcat' package(s) announced via the MGASA-2016-0367 advisory.
Vulnerability Insight:
The Realm implementations did not process the supplied password if the
supplied user name did not exist. This made a timing attack possible to
determine valid user names. Note that the default configuration includes
the LockOutRealm which makes exploitation of this vulnerability harder
(CVE-2016-0762).
A malicious web application was able to bypass a configured
SecurityManager via a Tomcat utility method that was accessible to web
applications (CVE-2016-5018).
It was discovered that the Tomcat packages installed configuration file
/usr/lib/tmpfiles.d/tomcat.conf writeable to the tomcat group. A member
of the group or a malicious web application deployed on Tomcat could use
this flaw to escalate their privileges (CVE-2016-5425).
It was discovered that the Tomcat packages installed certain
configuration files read by the Tomcat initialization script as
writeable to the tomcat group. A member of the group or a malicious web
application deployed on Tomcat could use this flaw to escalate their
privileges (CVE-2016-6325).
When a SecurityManager is configured, a web application's ability to
read system properties should be controlled by the SecurityManager.
Tomcat's system property replacement feature for configuration files
could be used by a malicious web application to bypass the
SecurityManager and read system properties that should not be visible
(CVE-2016-6794).
A malicious web application was able to bypass a configured
SecurityManager via manipulation of the configuration parameters for the
JSP Servlet (CVE-2016-6796).
The ResourceLinkFactory did not limit web application access to global
JNDI resources to those resources explicitly linked to the web
application. Therefore, it was possible for a web application to access
any global JNDI resource whether an explicit ResourceLink had been
configured or not (CVE-2016-6797).
Affected Software/OS:
'tomcat' package(s) on Mageia 5.
Solution:
Please install the updated package(s).
CVSS Score:
