pseudo variable cache + app_lua = potential memory leak

by Timo Teras

Hi, I was recently debugging a memory leak in Kamailio running lua code. And it turned out to be rather nasty interaction with the PV cache and the Lua code. Technically, this is bug in Kamailio. However, we ended up fixing the lua code because the same bug also introduces security issues. The problem is that PV cache never releases cached items. Normally this is not a problem since in .cfg files you can only access PVs with fixed name. In cases where dynamic part is needed, like $sht() access based on variable, the expansion is done in the PV expression evaluation and the actual PV name is still static. However, app_lua exposes sr.pv.* where the PV name is a string. The lua application is free to construct it as it wishes. The case I had was using lua code to expand a variable, and then do sr.pv.get/sets on the expanded "$sht(table=>"..key..")" type expression. This resulted PV core leaking cached entry for each unique key. So I wonder if should limit the PV cache size, and e.g. make the bucket chain size limited (start releasing oldest cache entries when the bucket becomes full)? Or if this is not possible, e.g. due to memory allocation semantics, at least put big fat warning to the app_lua's sr.pv.* documentation on this. I ended up just fixing the application to set it first to "$var(tmp)" and then use that in the PV query. The security implication is noticeable if 'key' comes from untrusted source (e.g. SIP message) as then an attacker can inject string for PV expansion... Thanks, Timo

[kamailio/kamailio] To make work user-agent for http_client module you need to load utils module too (#705)

by Jurijs Ivolga

Hi, I found strange bug. When I load utils and http_client modules then user-agent are sent in http request using http_client module(http_connect funcion), but if I do not load utils module, then user-agent is not sent anymore. Thank you! --- You are receiving this because you are subscribed to this thread. Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/705
