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).

Solution :

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

Risk factor :

High / CVSS Base Score : 7.5
