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: 5.9
SynopsisThe remote Scientific Linux host is missing one or more security updates.
DescriptionThe IcedTea-Web project provides a Java web browser plug-in and an implementation of Java Web Start, which is based on the Netx project.
It also contains a configuration tool for managing deployment settings for the plug-in and Web Start implementations.
An uninitialized pointer use flaw was found in the IcedTea-Web plug-in. Visiting a malicious web page could possibly cause a web browser using the IcedTea-Web plug-in to crash, disclose a portion of its memory, or execute arbitrary code. (CVE-2012-3422)
It was discovered that the IcedTea-Web plug-in incorrectly assumed all strings received from the browser were NUL terminated. When using the plug-in with a web browser that does not NUL terminate strings, visiting a web page containing a Java applet could possibly cause the browser to crash, disclose a portion of its memory, or execute arbitrary code. (CVE-2012-3423)
This erratum also upgrades IcedTea-Web to version 1.2.1.
All IcedTea-Web users should upgrade to these updated packages, which resolve these issues. Web browsers using the IcedTea-Web browser plug-in must be restarted for this update to take effect.
SolutionUpdate the affected icedtea-web, icedtea-web-debuginfo and / or icedtea-web-javadoc packages.
