             Bug #: 47207
           Summary: CMapCache::getCMap SEGV with
                    'Creusage_-_Tunnel_sous_la_Manche.pdf' fonts
    Classification: Unclassified
           Product: poppler
           Version: unspecified
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: general

Page 7 11kB minimal from 'pdftk burst Creusage*.pdf'

Forwarded from: https://bugs.launchpad.net/ubuntu/+source/poppler/+bug/952314

The following PDF reliably causes xpdf and Evince to crash/hang:

 
http://www.gramme.be/unite9/pmwiki/uploads/PrGC0708/Creusage_-_Tunnel_sous_la_Manche.pdf

Even when the file is split up into separate pages using 'pdftk burst', all
pages still cause the crash, including the smallest one at 11kB; the crash is
likely related to the loading of one of the embedded fonts.

Ideally even if Poppler can't handle a particular font, it should not result in
a crash.
