MU41 breaks /tmp

[HostaHost]

Had an occurrence last night of MU41 installing and then /tmp ends up with the following permissions and ownership:

drwxrwx---. 8 apache psacln 4096 Aug 3 09:37 tmp

Any ideas how that would have happened? It of course broke everything except apache.

Another day, another broken server; thanks for no response so far.

I'm not sure what response you are expecting, but it's easy enough to infer that the following script is to blame:

https://autoinstall.plesk.com/PSA_10.4.4/microupdates/common/mu_session_path.sh

It has several flaws, one of them being failure to check that session.save_path value is a default one for a given OS (or in other way restrict potential adverse effects of changing permissions).

Just fix your /tmp permissions. It restricts itself to running only once, so don't worry.

I can confirm this issue. We have seen /tmp permissons changed on all Plesk 10.4 machines after MU #41 was installed. Again a wonderful example of the lack of testing at Parallels.

Worth noting that we use /tmp as PHP's session.save_path instead of the default value.

Hostasaurus.Com, Tozz I'm sorry, I have missed this aspect. It was my fault.
