RE: [tdf-discuss] LibreOffice and Java Security: OpenJDK Vulnerability


<http://lists.grok.org.uk/pipermail/full-disclosure/2013-January/089440.html>

It appears that the particular reflection feature in Java 7 is the security-exploit gift that just 
keeps on giving.  The answer is still to disable Java plug-ins in browsers and have Java installed 
only if you depend on it for something (certain LibreOffice extensions, Base, other Java-based 
applications, etc.).

Simon has just provided a superb account of the Java security problem in an InfoWorld blog post 
today:
<http://www.infoworld.com/t/java-programming/why-fixing-the-java-flaw-will-take-so-long-210946>.

I find this more-technical analysis to be plausible as well, and Simon's report provides context 
that makes it a bit more understandable:

For users of openoffice-lineage software, I am not sure what the concern should be.  Disabling java 
browser plugins seems prudent.  It may be inevitable that web sites will cease depending on users 
employing such plugins with the famed Java Applet disappearing into history.

I'm investigating, but the issue is a sandbox security manager bypass using
unauthorised reflection and that's exploited using Rhino Javascript. So the
context has to be a browser for there to be an issue even if OpenJDK is
affected. See https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2013-0422 for
lots of data...
