Description David Walser 2014-03-28 16:49:21 CET
The exact problem I was seeing was backing up a course in Moodle, it would crash halfway through performing the backup, causing httpd to segfault.

Upgrading libzip fixes this problem.

Updated packages uploaded for Mageia 4 and Cauldron.


The libzip library has been updated to version 0.11.2, which fixes crashes
that affected php-zip and possibly other users of the library.

Updated packages in core/updates_testing:

from libzip-0.11.2-1.mga4.src.rpm

Comment 1 David Walser 2014-04-04 18:55:06 CEST
There's a simple PoC on Bug 13050:
$za = new ZipArchive();
$result = $za->open("/tmp/test.zip", $flags);

Save that in a file called ziptest.php, install php-zip and php-cli, and run it as "php ziptest.php"

It should segfault before the libzip update, and not segfault after it.

I've confirmed the PoC is fixed on Mageia 4 i586.

PoC is fixed on Mageia 4 x86-64 (in a VBox VM). It was broken before the upgrade.

Comment 3 David Walser 2014-04-04 19:29:26 CEST
Thanks Shlomi!  Since I've confirmed the fix on i586 with both Moodle and the script in Comment 1, this could be validated.
Comment 4 Shlomi Fish 2014-04-04 19:35:57 CEST
PoC exploit segfaults on a Mageia 4 i586 VM before the update and is fixed on it after the update. Marking as MGA4-32-OK .
