Subject: | libnet-cups-perl: Segfaults in Net::CUPS::PPD method getNextOption when enumerating options |
We have the following bug reported to the Debian package of Net-CUPS
(https://bugs.debian.org/681085):
It doesn't seem to be a bug in the packaging, so you may want to take
a look. Thanks!
Please note that the bug report also contains a proposed patch.

Package: libnet-cups-perl
Version: 0.60-1
Severity: important
Tags: upstream
The following Perl script will crash with a segmentation fault. The expected
behaviour of getNextOption when there are no options left is to return undef.
use Net::CUPS;
use Net::CUPS::Destination;
use Net::CUPS::PPD;
use Data::Dumper;
use strict;
my $cups=Net::CUPS->new();
my $printer=$cups->getDestination("someprinter");
my $name=$printer->getName();
print("Printer name: $name\n");
my @options=$printer->getOptions();
foreach my $line (@options) {
my $opt=$printer->getOptionValue($line);
print("option: $line = $opt\n");
}
print("\n--- PPD options\n");
my $ppd=$cups->getPPD("tardisjet");
while(my $opt=$ppd->getNextOption()) {
print("Option:\n");
print Dumper $opt;
}
