Issue:
Process is taking huge memory due to creation of 2 billion character "<". This will also lead to OutOfMemoryError within the process.
Reason:
In Class MediaFieldParser.java -- MediaFieldParser.mediaField()
if (Debug.parserDebug) Check is missing in the below code. dbg_leave("mediaField"); is being called without the 'if (Debug.parserDebug)' check.
} finally {
dbg_leave("mediaField");
}
ParserCore.dbg_enter(String rule) are not called since debugging is not enabled at the process.
In ParserCore.dbg_leave(String rule) nesting_level variable will be decremented by one every functioncall.
Finally after 2147483647 function calls, The nesting_level variable will have -2147483648.
On the next function call -2147483648 -1, Will nesting_level variable will have the value of 2147483647.
This leads to the creation of 2147483647 characters '<' .
protected void dbg_leave(String rule) {
StringBuilder stringBuilder = new StringBuilder();
for (int i = 0; i < nesting_level ; i++)
stringBuilder.append("<");
if (debug) {
System.out.println(
stringBuilder +
rule +
"\nlexer buffer = \n" +
lexer.getRest());
}
nesting_level --;
}
Fix:
Please add if (Debug.parserDebug) in MediaFieldParser.mediaField().
} finally {
if (Debug.parserDebug)
dbg_leave("mediaField");
}
