Severity: normal

Usertags: pu
Dear release team,
this is a follow-up for #927433 (about +deb9u2).
+ * debian/patches/1047_CVE-2019-14466-1_replace_unserialize_with_json_
+ encode+json_decode.patch:
+ + Replace (un)serialize with json_encode/json_decode to mitigate PHP object
+ injection (CVE-2019-14466).
Since I last uploaded the stretch-pu of gosa, one more CVE issue got
known and already addressed in the Git branch.
I will follow-up with a +deb9u3 upload on the +deb9u2 upload. Luckily,
this one is not as massive as the +deb9u2 one.
Greets,
Mike

+Subject: [PATCH] Fix the decoding of filter settings cookie
+
+Previously, the use of json_decode without a second paramter meant that an
+stdClass was returned, which does not allow access to properties via the index
+operator. Instead, we now use json_decode(..., true) to return an associative
+array.
+
+In order to prevent any type shenanigans, we also ensure whether the returned
+value is an array and if not, replace it with an empty one.
