Subject: [ruby-core:61252] [ruby-trunk - Bug #9588] program name variables tainted
Date: Mon, 03 Mar 2014 10:59:30 +0000 [thread overview]
Message-ID: <redmine.journal-45592.20140303105930.774863c2620e77e9@ruby-lang.org> (raw)
In-Reply-To: redmine.issue-9588.20140303090945@ruby-lang.org
Issue #9588 has been updated by Shyouhei Urabe.
My expectation to tainted.rb output is what 1.8.7 outputs. This seems like a regression to me.
----------------------------------------
Bug #9588: program name variables tainted
https://bugs.ruby-lang.org/issues/9588#change-45592
* Author: Jan Rusnacko
* Status: Open
* Priority: Normal
* Assignee:
* Category:
* Target version:
* ruby -v: 1.8.7, 1.9.3, 2.0.0
* Backport: 1.9.3: UNKNOWN, 2.0.0: UNKNOWN, 2.1: UNKNOWN
----------------------------------------
I have noticed inconsistency in taint flag of program name:
[jrusnack@dhcp-31-42 ruby-safe]$ cat tainted.rb
#!/usr/bin/env ruby
puts "$0: #{$0}, tainted? #{$0.tainted?}"
puts "__FILE__: #{__FILE__}, tainted? #{__FILE__.tainted?}"
puts "$PROGRAM_NAME: #{$PROGRAM_NAME}, tainted? #{$PROGRAM_NAME.tainted?}"
[jrusnack@dhcp-31-42 ruby-safe]$ rvm use 1.8.7
Using /home/jrusnack/.rvm/gems/ruby-1.8.7-p374
[jrusnack@dhcp-31-42 ruby-safe]$ ./tainted.rb
$0: ./tainted.rb, tainted? true
__FILE__: ./tainted.rb, tainted? false
$PROGRAM_NAME: ./tainted.rb, tainted? true
[jrusnack@dhcp-31-42 ruby-safe]$ rvm use 1.9.3
Using /home/jrusnack/.rvm/gems/ruby-1.9.3-p484
[jrusnack@dhcp-31-42 ruby-safe]$ ./tainted.rb
$0: ./tainted.rb, tainted? false
__FILE__: ./tainted.rb, tainted? true
$PROGRAM_NAME: ./tainted.rb, tainted? false
[jrusnack@dhcp-31-42 ruby-safe]$ rvm use 2.0.0
Using /home/jrusnack/.rvm/gems/ruby-2.0.0-p353
[jrusnack@dhcp-31-42 ruby-safe]$ ./tainted.rb
$0: ./tainted.rb, tainted? false
__FILE__: ./tainted.rb, tainted? true
$PROGRAM_NAME: ./tainted.rb, tainted? false
