"Abort pclzip.lib.php" error during comfort update was created by hrcittl
Hey there everyone,

I'm getting a "Abort pclzip.lib.php : Unzipped file is superior to upload_max_filesize or to post_max_size" on the last stage of a comfortupdate (from 3.14.8+180829 to 3.14.10 (180924)).

I've increased the size limits in both php.ini files (the CLI one, and the other one).

Still getting the error though. Any other ideas?

hi,

that's the new "zip bomb" prevention:
github.com/LimeSurvey/LimeSurvey/blob/ma...mon_helper.php#L5041

you must increase "upload_max_filesize" in your php configuration.

since many people are facing problem with this function, we will add a configuration parameter to change its values from limesurvey configuration rather than php configuration.

Since it can be forced by admin …

Else : zip bomb must not be tested for comortupdate : it's an issue here ? No ?

So this cannot be fixed now otherwise then set upload_max_filesize?

Really strange order to first add something new, and then go think of a solution of how to fix what the new messes up...

In latest version, you can change it in config.php:
github.com/LimeSurvey/LimeSurvey/commit/...873f3ae940c3a91a56ce

"maximum_unzipped_size"

By default it's at 500Mb

Indeed. Meanwhile, I need to update to get the new size setting so that I can change it and update. But I can't update (through comfortupdate) because I don't have the size setting.

I guess I'm going to have to manually update from github to get the setting so I can comfortupdate again. First to find the time to figure out *how* to do that, and then do it.

Why not change the content of the two files manually?
github.com/LimeSurvey/LimeSurvey/commit/...873f3ae940c3a91a56ce

You will run into more trouble switching from comfortupdate to github and back.
So just modfiy these two files.

If you subscribe to a limeSurvey CE package I can create for you a zip file to update easily

It is not clear to me how to address this issue with ComfortUpdate.
I cannot access any filesystem.

"upload_max_filesize" was set to 32MB, but that was not enough.
What should it be set to then?

thnx

What do you mean with "filesystem"?

And then: is your problem exactly the same, because only then this solution mentioned here will help.
Help us to help you!
  • Provide your LS version and where it is installed (own server, uni/employer, SaaS hosting, etc.).
  • Always provide a LSS file (not LSQ or LSG).
