-----------------------------------
Summary: Infinte loop when parsing Type1 font
Key: PDFBOX-5624
URL: https://issues.apache.org/jira/browse/PDFBOX-5624
Project: PDFBox
Issue Type: Bug
Components: FontBox
Affects Versions: 2.0.28
Reporter: Timo Boehme
Assignee: Timo Boehme
At 2 places the Type1Parser has a loop with a negated condition on the next
token to be read. The loops simply advances to the next token without checking
the token to be null, which may happen if the font is corrupted/shortened. If
this occurs the parser is stuck in the loops. This happens to me for one of the
loops with a file which however cannot be shared. The 2nd loop was found by
scanning the code for similar problems.
