Format string vulnerability in the zend_throw_or_error function in Zend/zend_execute_API.c in PHP 7.x before 7.0.1 allows remote attackers to execute arbitrary code via format string specifiers in a string that is misused as a class name, leading to incorrect error handling.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
