There is an invalid memory access in the function TextString::~TextString()
located in Catalog.cc in Xpdf 4.0.2. It can be triggered by (for example)
sending a crafted pdf file to the pdftohtml binary, which allows a remote
attacker to cause a Denial of Service (Segmentation fault) or possibly have
unspecified other impact.
Notes

| mdeslaur | Doesn’t look like the same issue is in poppler, there is no Catalog.PageLabels |
| ebarretto | xpdf in Debian uses poppler, which is not affected or fixed |
