Apparently our PHP package is vulnerable to CVE-2017-11144,
CVE-2017-11145, and CVE-2017-11362:


This one looks especially bad:


Can someone please take a look at this?

Hi Leo,

I've just submitted a patch to update PHP to version 7.1.7, which
resolves the CVEs. Unfortunately PHP has 4 test errors on my machine
(but also on the previous version), so I could not fully build it
(disabling tests results in a working version of PHP).

The relevant patch is at 27826. If someone could try building it, on
x86_64 then we could be sure it's just my local environment that messes
things up…

OK that's what I've got too.

I guess it will need some investigation… :-(

Thanks for testing!

Any update? :-)

Would be good not to leave the vulnerable version in the distro.

TIA,

Agreed, though I am in no position to investigate this. I was going to
propose a patch that disabled those 4 tests, but I will need to
investigate how to do that. So at the earliest I could contribute those
patches this weekend.

Hi

I believe this issue is now resolved as Julien Lepiller seems to have
pushed a working version of PHP 7.1.8 on 3 August with commit
1cec3462323717e063c98b6404e9c5c5ef037bdd.

I will try to close the bugs (27826 & 27808).
