CVE-2016-7414 (opens in a new tab)How to fix?
Upgrade RHEL:7 rh-php70-php-opcache to version 0:7.0.27-1.el7 or higher.
This issue was patched in RHSA-2018:1296.
NVD Description
Note: Versions mentioned in the description apply only to the upstream rh-php70-php-opcache package and not the rh-php70-php-opcache package as distributed by RHEL.
See How to fix? for RHEL:7 relevant fixed versions and status.
The ZIP signature-verification feature in PHP before 5.6.26 and 7.x before 7.0.11 does not ensure that the uncompressed_filesize field is large enough, which allows remote attackers to cause a denial of service (out-of-bounds memory access) or possibly have unspecified other impact via a crafted PHAR archive, related to ext/phar/util.c and ext/phar/zip.c.
