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

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

Chamal De Silva discovered that the IcedTea-Web Java web browser plugin could dereference an uninitialized pointer. A remote attacker could use this to craft a malicious web page that could cause a denial of service by crashing the web browser or possibly execute arbitrary code. (CVE-2012-3422)

Steven Bergom and others discovered that the IcedTea-Web Java web browser plugin assumed that all strings provided by browsers are NULL terminated, which is not guaranteed by the NPAPI (Netscape Plugin Application Programming Interface). A remote attacker could use this to craft a malicious Java applet that could cause a denial of service by crashing the web browser, expose sensitive information or possibly execute arbitrary code. (CVE-2012-3423).

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

Solution

Update the affected icedtea-6-plugin and / or icedtea-7-plugin packages.
