> DESCRIPTION:
> Daniel Soeder has reported a vulnerability in Sun Java JRE, which can
> be exploited by malicious people to compromise a user's system.
>
> The vulnerability is caused due to a boundary error within the Java
> Web Start component (javaws.exe) when processing JNLP files. This can
> be exploited to cause a stack-based buffer overflow via a specially
> crafted JNLP file with an overly long codebase attribute.
>
> Successful exploitation allows execution of arbitrary code e.g. when
> a user visits a malicious website.
>
> The vulnerability is reported in the following versions:
> * Java Runtime Environment 6 Update 1 and earlier
> * Java Runtime Environment 5 Update 11, and earlier
>
> SOLUTION:
