CentOS Update for java CESA-2015:1526 centos5

Published: 2015-08-10 07:28:28
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:N/AC:L/Au:N/C:C/I:C/A:C

Detection Type:
Linux Distribution Package

Summary:
Check the version of java

Detection Method:
Checks if a vulnerable version is present on the target host.

Technical Details:
The java-1.6.0-openjdk Linux Distribution Packages provide the OpenJDK 6 Java Runtime Environment and the OpenJDK 6 Java Software Development Kit. Multiple flaws were discovered in the 2D, CORBA, JMX, Libraries and RMI components in OpenJDK. An untrusted Java application or applet could use these flaws to bypass Java sandbox restrictions. (CVE-2015-4760, CVE-2015-2628, CVE-2015-4731, CVE-2015-2590, CVE-2015-4732, CVE-2015-4733) A flaw was found in the way the Libraries component of OpenJDK verified Online Certificate Status Protocol (OCSP) responses. An OCSP response with no nextUpdate date specified was incorrectly handled as having unlimited validity, possibly causing a revoked X.509 certificate to be interpreted as valid. (CVE-2015-4748) It was discovered that the JCE component in OpenJDK failed to use constant time comparisons in multiple cases. An attacker could possibly use these flaws to disclose sensitive information by measuring the time used to perform operations using these non-constant time comparisons. (CVE-2015-2601) A flaw was found in the RC4 encryption algorithm. When using certain keys for RC4 encryption, an attacker could obtain portions of the plain text from the cipher text without the knowledge of the encryption key. (CVE-2015-2808) Note: With this update, OpenJDK now disables RC4 TLS/SSL cipher suites by default to address the CVE-2015-2808 issue. Refer to Red Hat Bugzilla bug 1207101, linked to in the References section, for additional details about this change. A flaw was found in the way the TLS protocol composed the Diffie-Hellman (DH) key exchange. A man-in-the-middle attacker could use this flaw to force the use of weak 512 bit export-grade keys during the key exchange, allowing them to decrypt all traffic. (CVE-2015-4000) Note: This update forces the TLS/SSL client implementation in OpenJDK to reject DH key sizes below 768 bits, which prevents sessions to be downgraded to export-grade keys. Refer to Red Hat Bugzilla bug 1223211, linked to in the References section, for additional details about this change. It was discovered that the JNDI component in OpenJDK did not handle DNS resolutions correctly. An attacker able to trigger such DNS errors could cause a Java application using JNDI to consume memory and CPU time, and possibly block further DNS resolution. (CVE-2015-4749) Multiple information leak flaws were found in the JMX and 2D components in OpenJDK. An untrusted Java application or applet could use this flaw to bypass certain Java sandbox restrictions. (CVE-2015-2621, CVE-2015-2632) A flaw was found in the way the JSSE component in OpenJDK performed X.509 certificate ident ...

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
