             Summary: Infiniteloop BaseParser.java:1010
                 Key: PDFBOX-1796
                 URL: https://issues.apache.org/jira/browse/PDFBOX-1796
             Project: PDFBox
          Issue Type: Bug
          Components: Parsing
    Affects Versions: 1.8.3
            Reporter: Manfred Schauer


infinite loop at org.apache.pdfbox.pdfparser.BaseParser.parseCOSHexString(BaseParser.java:1010)

private final COSString parseCOSHexString() throws IOException
{
...
            // read till the closing bracket was found
            do 
            {
                c = pdfSource.read();
            } while ( c != '>' );
...   

if pdfSource.read() returns EOF, the loop never terminates;

Testcase:
PDDocument doc = PDDocument.load (new FileInputStream("..."));

2 real world pdf-files that cause the loop could be attached; do not know if their PDF is completely valid, but at least they are displayed via Preview in MacOSX.
