CVE-2019-2949

Priority
Description
Vulnerability in the Java SE, Java SE Embedded product of Oracle Java SE
(component: Kerberos). Supported versions that are affected are Java SE:
7u231, 8u221, 11.0.4 and 13; Java SE Embedded: 8u221. Difficult to exploit
vulnerability allows unauthenticated attacker with network access via
Kerberos to compromise Java SE, Java SE Embedded. While the vulnerability
is in Java SE, Java SE Embedded, attacks may significantly impact
additional products. Successful attacks of this vulnerability can result in
unauthorized access to critical data or complete access to all Java SE,
Java SE Embedded accessible data. Note: This vulnerability applies to Java
deployments, typically in clients running sandboxed Java Web Start
applications or sandboxed Java applets (in Java SE 8), that load and run
untrusted code (e.g., code that comes from the internet) and rely on the
Java sandbox for security. This vulnerability can also be exploited by
using APIs in the specified Component, e.g., through a web service which
supplies data to the APIs. CVSS 3.0 Base Score 6.8 (Confidentiality
impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:N/A:N).
Ubuntu-Description
Rob Hamm discovered that the Kerberos implementation in OpenJDK did
not properly handle proxy credentials. An attacker could possibly
use this to impersonate another user.
