Package: netdisco-mibs-installer
Version: 1.5
Severity: normal
Tags: upstream patch
If you run netdisco-mibs-download twice, the second run exits with
status 3 and the following error message:
/tmp/netdisco-mibs exists and is not a root-owned directory with
permissions set to 0755 (or less)
The message was introduced in the fix to #508940 (CVE-2008-5379[0]).
That patch contained some faulty bit manipulation in Perl. In essence,
the code assumes that the following snippet outputs 0, but it doesn't:
$ perl -Mfeature=say -e 'say 0755 - "0755"'
-262
The bug is present in netdisco-mibs-installer 1.5 (squeeze) all the way
to 1.7.1 (the latest upstream release).
