-------------------------------
Summary: PnmImageParser does not check the validity of input PAM
header
Key: IMAGING-178
URL: https://issues.apache.org/jira/browse/IMAGING-178
Project: Commons Imaging
Issue Type: Bug
Components: Format: PNM
Reporter: emopers
PnmImageParser.java directly calls tokenizer.nextToken() at line no 160, 163,
166, 169 and 172 on java.util.StringTokenizer tokenizer without checking if
there are more tokens. Because tokenizer is built from the bytes string that
can be invalid, this can lead to a runtime exception without a useful error
message. This can be easily fixed by calling tokenizer.hasMoreTokens() before
calling tokenizer.nextToken() at each line number mentioned before and throwing
useful error message.
