[Bug 2177239] New: Lua scripts use an unsafe package path

by bugzilla＠redhat.com

https://bugzilla.redhat.com/show_bug.cgi?id=2177239 Bug ID: 2177239 Summary: Lua scripts use an unsafe package path Product: Fedora Version: 37 Status: NEW Component: lua Assignee: spotrh(a)gmail.com Reporter: arstoffel(a)gmail.com QA Contact: extras-qa(a)fedoraproject.org CC: 4le(a)live.com, drjohnson1(a)gmail.com, lua-packagers-sig(a)lists.fedoraproject.org, mhroncok(a)redhat.com, michel(a)michel-slm.name, spotrh(a)gmail.com Target Milestone: --- Classification: Fedora Description of problem: By default, Lua allows loading code from the current directory, and Fedora doesn't change this in packaged scripts installed in the system path. This has security implications. Steps to Reproduce: 1. Install any package that provides a #!/usr/bin/lua script, such as (but not limited) to luarocks 2. In the terminal: echo 'os.execute("echo rm -rf /")' > lfs.lua; luarocks --version Actual results: $ luarocks --version rm -rf / /usr/bin/lua: /usr/share/lua/5.4/luarocks/fs/lua.lua:299: attempt to index a boolean value (upvalue 'lfs') stack traceback: /usr/share/lua/5.4/luarocks/fs/lua.lua:299: in function 'luarocks.fs.lua.current_dir' (...tail calls...) /usr/share/lua/5.4/luarocks/fs/unix.lua:50: in function 'luarocks.fs.unix.absolute_name' (...tail calls...) /usr/share/lua/5.4/luarocks/fs/linux.lua:8: in function 'luarocks.fs.linux.is_dir' (...tail calls...) /usr/share/lua/5.4/luarocks/fs/lua.lua:193: in function 'luarocks.fs.lua.dir' (...tail calls...) /usr/share/lua/5.4/luarocks/fs/lua.lua:177: in function 'luarocks.fs.lua.list_dir' (...tail calls...) /usr/share/lua/5.4/luarocks/fs/lua.lua:229: in function 'luarocks.fs.lua.modules' (...tail calls...) /usr/share/lua/5.4/luarocks/cmd.lua:511: in function 'luarocks.cmd.run_command' /home/augusto/Projects/digestif/.luarocks/lib/luarocks/rocks-5.4/luarocks/3.9.2-1/bin/luarocks:35: in main chunk [C]: in ? Expected results: $ luarocks --version /usr/bin/luarocks 3.9.1 LuaRocks main command-line interface Additional info: I'm using the following fix on a Lua program I maintain: #!/usr/bin/env lua -- Remove relative directories from package path package.path = package.path:gsub("%f[^\0;]%.[^;]*", ""):gsub(";+", ";"):gsub("^;", ""):gsub(";$", "") package.cpath = package.cpath:gsub("%f[^\0;]%.[^;]*", ""):gsub(";+", ";"):gsub("^;", ""):gsub(";$", "") Fedora can probably do better and use hardcoded pacakge.path and cpath values, since these are known in advance. Scripts with the #!/usr/bin/texlua shebang also might be affected by this issue. Since texlua provides an alternative method to find packages based on kpathsea, something like this should be used as well: os.setenv("TEXMFDOTDIR", "/dev/null") However, this last modification will break programs that expect to find TeX files in the current directory. I don't know of a more fine grained way that would allow that but still exclude random Lua libraries from being found. -- You are receiving this mail because: You are on the CC list for the bug. https://bugzilla.redhat.com/show_bug.cgi?id=2177239
