Summary: Hangup in COSFilterInputStream.nextRange
Key: PDFBOX-5395
URL: https://issues.apache.org/jira/browse/PDFBOX-5395
Project: PDFBox
Issue Type: Bug
Affects Versions: 2.0.25
Reporter: Aleksej Kozlov
On some broken PDFs call _PDSignature.getSignedContent_ never returns.
After exploring stacktrace I've found cycle in _COSFilterInputStream.nextRange_.
{code:java}
while (this.position < this.ranges[this.range][0])
{
long skipped = super.skip(this.ranges[this.range][0] -
this.position);
this.position += skipped;
}
{code}
Javadoc for _skip_ says _"The skip method may, for a variety ofreasons, end up
skipping over some smaller number of bytes, possibly 0."_
So, when _skip_ returns 0 this cycle became infinite.
Tried in versions 2.0.25 and 3.0.0-RC1.
