Bug#881201: pdfchain: input is not quoted and poured into the shell as it is

[Peter Gervai]

Package: pdfchain
Version: 1:0.4.4.2-1
Severity: important
Tags: upstream

Input should be either always single quoted or taken care of. 
A password like hey&rm -rf / can make funny effects. Even if not, it results a 
pdftk error at best.
Cryptic one.
