Bug 22377

Repeating the same PoC Len did in:
https://bugs.mageia.org/show_bug.cgi?id=22352#c3

Before:
$ pdftotext 0JBYrSy8_CRASHED.pdf 
Syntax Error: Embedded font file may be invalid
Syntax Error (20431): Unknown operator 'TJJJJJJJJJJJJJJ'
Segmentation fault

After:
$ pdftotext 0JBYrSy8_CRASHED.pdf 
Syntax Error: Embedded font file may be invalid
Syntax Error (20431): Unknown operator 'TJJJJJJJJJJJJJJ'
Syntax Warning: wordBaseIdx out of range
Syntax Warning: wordBaseIdx out of range
Syntax Warning: wordBaseIdx out of range
Syntax Warning: wordBaseIdx out of range
Syntax Error (17678): Bad 'Length' attribute in stream
Syntax Warning: wordBaseIdx out of range

Looks good on Mageia 5 x86_64.

Whiteboard: (none) => MGA5-64-OK

Testing on Mageia 5 :: x86_64
Tried the POC before updating:
$ pdftotext 0JBYrSy8_CRASHED.pdf
Syntax Error: Embedded font file may be invalid
Syntax Error (20431): Unknown operator 'TJJJJJJJJJJJJJJ'
Segmentation fault

The POC test file can be traced via the CVE-2017-1000456 link.
Clean update for the 12 packages.
$ pdftotext 0JBYrSy8_CRASHED.pdf
Syntax Error: Embedded font file may be invalid
Syntax Error (20431): Unknown operator 'TJJJJJJJJJJJJJJ'
Syntax Warning: wordBaseIdx out of range
Syntax Warning: wordBaseIdx out of range
Syntax Warning: wordBaseIdx out of range
Syntax Warning: wordBaseIdx out of range
Syntax Error (17678): Bad 'Length' attribute in stream
Syntax Warning: wordBaseIdx out of range

No segfault anyway.

Used an ebook to test the functionality:
$ pdfimages -all PythonCookbook_2.pdf cookbook
[lcl@difda books]$ ls cookbook*
cookbook-000.jp2   cookbook-003.jb2e  cookbook-006.jb2e  cookbook-009.jb2e
cookbook-001.jp2   cookbook-004.jp2   cookbook-007.jb2e
cookbook-002.jb2e  cookbook-005.jb2e  cookbook-008.jb2e
$ display cookbook-000.jp2
$ display cookbook-005.jb2e
display: no decode delegate for this image format `JB2E' @ error/constitute.c/ReadImage/504.
jb2e not recognized by ImageMagick so default to PNG.
$ rm -f cookbook*
$ pdfimages -png PythonCookbook_2.pdf cookbook
$ display cookbook-000.png
$ display cookbook-005.png
All the images displayed correctly.
$ pdfinfo PythonCookbook_2.pdf | grep Pages
Pages:          846
$ pdfseparate -f 11 -l 44 PythonCookbook_2.pdf pages%d.pdf
This produced 34 single page PDFs from pages 11 to 44, e.g. pages26.pdf.
A couple taken at random displayed properly in xpdf and okular.
Create a new pdf based on the extracted pages.
$ pdfunite pages*.pdf pages.pdf
That could be read with a pdf reader and contained the original page numbers.

pdfjam or pdfbook can be used to create books or booklets from a series of images and pdf files, if you can understand the help instructions.  Had to give up on that.

$ pdf2ps -dLanguageLevel=3 pages.pdf pages.ps
created a Postscript file which could be viewed page by page in gs by hitting Return repeatedly.  The pages were exact copies.  In this case the 34 pages translated to a 27 MB file.  Used less to examine it:
%!PS-Adobe-3.0
%%BoundingBox: 0 0 612 792
%%HiResBoundingBox: 0 0 612.00 792.00
%%Creator: GPL Ghostscript 922 (ps2write)
%%LanguageLevel: 2
%%CreationDate: D:20180113191008Z00'00'
%%Pages: 34
%%EndComments
%%BeginProlog
/DSC_OPDFREAD true def
/SetPageSize true def
/EPS2Write false def

This is all good enough for an OK.

Just collided with you David.  Thanks.
