Description Josh Bressers 2006-06-07 15:16:01 UTC
tiff2pdf buffer overflow

A buffer overflow flaw has been found in tiff2pdf.
Thomas Biege told vendor-sec about this (it came from a colleague of
his)

The code in question is as such:

char buffer[5];
...
sprintf(buffer, "\\%.3o", pdfstr[i]);


pdfstr[i] is signed char, therefore would write \37777777741


This issue also affects FC4

Fixed in FC5 by libtiff-3.8.2-1.fc6.

Comment 2 Jindrich Novy 2006-09-08 07:54:32 UTC
(or better by its equvalent in FC5: libtiff-3.8.2-1.fc5)
