CWE-416  (opens in a new tab)

How to fix?

There is no fixed version for RHEL:7 php-gd.

NVD Description

Note: Versions mentioned in the description apply only to the upstream php-gd package and not the php-gd package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

The unserialize implementation in ext/standard/var.c in PHP 7.x before 7.0.14 allows remote attackers to cause a denial of service (use-after-free) or possibly have unspecified other impact via crafted serialized data. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-6834.
