NVD Description
Note: Versions mentioned in the description apply only to the upstream rh-php70-php-pgsql package and not the rh-php70-php-pgsql 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.
