The version of Oracle (formerly Sun) Java Runtime Environment (JRE) 6.x installed on the remote host is earlier than Update 43. It, therefore, potentially can allow remote code execution due to the following vulnerabilities related to the ‘2D’ sub-component :
An integer overflow error exists related to handling sample model instances that could result in memory corruption leading to arbitrary code execution.
(CVE-2013-0809)
An unspecified error exists that could allow memory to be overwritten and could allow the security manager to be bypassed, thus leading to application crashes or arbitrary code execution. (CVE-2013-1493)
Please note this issue affects client deployments only and is exploited through untrusted ‘Java Web Start’ applications and untrusted Java applets.
