Vulnerability in the Java SE, Java SE Embedded, JRockit component of Oracle
10
Java SE (subcomponent: JNDI). Supported versions that are affected are Java
11
SE: 6u171, 7u161, 8u152 and 9.0.1; Java SE Embedded: 8u151; JRockit:
12
R28.3.16. Easily exploitable vulnerability allows unauthenticated attacker
13
with network access via multiple protocols to compromise Java SE, Java SE
14
Embedded, JRockit. Successful attacks require human interaction from a
15
person other than the attacker. Successful attacks of this vulnerability
16
can result in unauthorized ability to cause a partial denial of service
17
(partial DOS) of Java SE, Java SE Embedded, JRockit. Note: This
18
vulnerability applies to client and server deployment of Java. This
19
vulnerability can be exploited through sandboxed Java Web Start
20
applications and sandboxed Java applets. It can also be exploited by
21
supplying data to APIs in the specified Component without using sandboxed
22
Java Web Start applications or sandboxed Java applets, such as through a
23
web service. CVSS 3.0 Base Score 4.3 (Availability impacts). CVSS Vector:
24
(CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L).
26
It was discovered that the JNDI component of OpenJDK did not properly
27
restrict the amount of memory allocated when deserializing objects
28
in some situations. An attacker could use this to cause a denial of
29
service (excessive memory consumption).
