EulerOS 2.0 SP2 : java-1.7.0-openjdk (EulerOS-SA-2017-1208)

Synopsis :

The remote EulerOS host is missing multiple security updates.

Description :

According to the versions of the java-1.7.0-openjdk packages
installed, the EulerOS installation on the remote host is affected by
the following vulnerabilities :

- It was discovered that the DCG implementation in the
RMI component of OpenJDK failed to correctly handle
references. A remote attacker could possibly use this
flaw to execute arbitrary code with the privileges of
RMI registry or a Java RMI application.
(CVE-2017-10102)

- Multiple flaws were discovered in the RMI, JAXP,
ImageIO, Libraries, AWT, Hotspot, and Security
components in OpenJDK. An untrusted Java application or
applet could use these flaws to completely bypass Java
sandbox restrictions. (CVE-2017-10107, CVE-2017-10096,
CVE-2017-10101, CVE-2017-10089, CVE-2017-10090,
CVE-2017-10087, CVE-2017-10110, CVE-2017-10074,
CVE-2017-10067)

- It was discovered that the LDAPCertStore class in the
Security component of OpenJDK followed LDAP referrals
to arbitrary URLs. A specially crafted LDAP referral
URL could cause LDAPCertStore to communicate with
non-LDAP servers. (CVE-2017-10116)

- It was discovered that the wsdlimport tool in the
JAX-WS component of OpenJDK did not use secure XML
parser settings when parsing WSDL XML documents. A
specially crafted WSDL document could cause wsdlimport
to use an excessive amount of CPU and memory, open
connections to other hosts, or leak information.
(CVE-2017-10243)

- A covert timing channel flaw was found in the DSA
implementation in the JCE component of OpenJDK. A
remote attacker able to make a Java application
generate DSA signatures on demand could possibly use
this flaw to extract certain information about the used
key via a timing side channel. (CVE-2017-10115)

- A covert timing channel flaw was found in the PKCS#8
implementation in the JCE component of OpenJDK. A
remote attacker able to make a Java application
repeatedly compare PKCS#8 key against an attacker
controlled value could possibly use this flaw to
determine the key via a timing side channel.
(CVE-2017-10135)

- It was discovered that the BasicAttribute and
CodeSource classes in OpenJDK did not limit the amount
of memory allocated when creating object instances from
a serialized form. A specially crafted serialized input
stream could cause Java to consume an excessive amount
of memory. (CVE-2017-10108, CVE-2017-10109)

- A flaw was found in the Hotspot component in OpenJDK.
An untrusted Java application or applet could use this
flaw to bypass certain Java sandbox restrictions.
(CVE-2017-10081)

- It was discovered that the JPEGImageReader
implementation in the 2D component of OpenJDK would, in
certain cases, read all image data even if it was not
used later. A specially crafted image could cause a
Java application to temporarily use an excessive amount
of CPU and memory. (CVE-2017-10053)

Note that Tenable Network Security has extracted the preceding
description block directly from the EulerOS security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.
