CVE-2016-9138

Published: 4 January 2017

PHP through 5.6.27 and 7.x through 7.0.12 mishandles property modification during __wakeup processing, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via crafted serialized data, as demonstrated by Exception::__toString with DateInterval::__wakeup.

Notes

should not unserialize untrusted data

CVE-2016-9137 was for the ext/curl/curl_file.c vulnerability
that was fixed in the same bug. This CVE is for the remaining
security problem associated with __wakeup, which, as far as I
can tell is still unfixed as of 2020-06-23

As of 2022-02-04, there is still no upstream fix.
PHP Bug 73147 is mainly for CVE-2016-9137 and does not have
information for a new bug for CVE-2016-9138.
Suse has an indication that it might have been fixed along
with CVE-2016-7479 patch, but this is not perfectly clear.
