New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.
VPR Score: 9.4
SynopsisThe remote Red Hat host is missing one or more security updates.
DescriptionUpdated java-1.7.0-openjdk packages that fix various security issues are now available for Red Hat Enterprise Linux 6.
The Red Hat Security Response Team has rated this update as having critical security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.
These packages provide the OpenJDK 7 Java Runtime Environment and the OpenJDK 7 Software Development Kit.
Multiple flaws were discovered in the ImagingLib and the image attribute, channel, layout and raster processing in the 2D component.
An untrusted Java application or applet could possibly use these flaws to trigger Java Virtual Machine memory corruption. (CVE-2013-2470, CVE-2013-2471, CVE-2013-2472, CVE-2013-2473, CVE-2013-2463, CVE-2013-2465, CVE-2013-2469)
Integer overflow flaws were found in the way AWT processed certain input. An attacker could use these flaws to execute arbitrary code with the privileges of the user running an untrusted Java applet or application. (CVE-2013-2459)
Multiple improper permission check issues were discovered in the Sound, JDBC, Libraries, JMX, and Serviceability components in OpenJDK.
An untrusted Java application or applet could use these flaws to bypass Java sandbox restrictions. (CVE-2013-2448, CVE-2013-2454, CVE-2013-2458, CVE-2013-2457, CVE-2013-2453, CVE-2013-2460)
Multiple flaws in the Serialization, Networking, Libraries and CORBA components can be exploited by an untrusted Java application or applet to gain access to potentially sensitive information. (CVE-2013-2456, CVE-2013-2447, CVE-2013-2455, CVE-2013-2452, CVE-2013-2443, CVE-2013-2446)
It was discovered that the Hotspot component did not properly handle out-of-memory errors. An untrusted Java application or applet could possibly use these flaws to terminate the Java Virtual Machine.
It was discovered that the AWT component did not properly manage certain resources and that the ObjectStreamClass of the Serialization component did not properly handle circular references. An untrusted Java application or applet could possibly use these flaws to cause a denial of service. (CVE-2013-2444, CVE-2013-2450)
It was discovered that the Libraries component contained certain errors related to XML security and the class loader. A remote attacker could possibly exploit these flaws to bypass intended security mechanisms or disclose potentially sensitive information and cause a denial of service. (CVE-2013-2407, CVE-2013-2461)
It was discovered that JConsole did not properly inform the user when establishing an SSL connection failed. An attacker could exploit this flaw to gain access to potentially sensitive information.
It was discovered that GnomeFileTypeDetector did not check for read permissions when accessing files. An untrusted Java application or applet could possibly use this flaw to disclose potentially sensitive information. (CVE-2013-2449)
It was found that documentation generated by Javadoc was vulnerable to a frame injection attack. If such documentation was accessible over a network, and a remote attacker could trick a user into visiting a specially crafted URL, it would lead to arbitrary web content being displayed next to the documentation. This could be used to perform a phishing attack by providing frame content that spoofed a login form on the site hosting the vulnerable documentation. (CVE-2013-1571)
It was discovered that the 2D component created shared memory segments with insecure permissions. A local attacker could use this flaw to read or write to the shared memory segment. (CVE-2013-1500)
Red Hat would like to thank Tim Brown for reporting CVE-2013-1500, and US-CERT for reporting CVE-2013-1571. US-CERT acknowledges Oracle as the original reporter of CVE-2013-1571.
Note: If the web browser plug-in provided by the icedtea-web package was installed, the issues exposed via Java applets could have been exploited without user interaction if a user visited a malicious website.
After installing this update, users of icedtea-web must install RHBA-2013:0959 for icedtea-web to continue functioning.
This erratum also upgrades the OpenJDK package to IcedTea7 2.3.10.
