> URL: https://issues.apache.org/jira/browse/MYFACES-3476
> Project: MyFaces Core
> Issue Type: Bug
> Components: JSR-314
> Affects Versions: 2.0.12
> Environment: MyFaces 2.0.12, Richfaces 4.1.0.Final, Tomcat 6, Linux
> Reporter: James G
> Assignee: Leonardo Uribe
> Priority: Critical
> Fix For: 2.0.13, 2.1.7

>
> When the filter (CDataEndEscapeFilterWriter) parses 2 CDATA End tags, it
> passes an incorrect length to the writer throwing an exception further down
> the stack. The incorrect length comes from the method write(char[] cbuf, int
> off, int len). On the second match of the end tag the (offset+length) passed
> to the super.write can be greater than the (offset+length) passed to the
> method. Suggested fix:
> change index = i+1; to index = off+i+1; and
> change super.write(cbuf, index, i+1);
> to super.write(cbuf, index, i+1 - ( index - off ) );
