CVE-2016-5773
CRITICALPHP < 5.5.37, 5.6.x < 5.6.23, 7.x < 7.0.8 - Remote Code Execution via ZipArchive Unserialize Use-After-Free
Title source: manualDescription
php_zip.c in the zip extension in PHP before 5.5.37, 5.6.x before 5.6.23, and 7.x before 7.0.8 improperly interacts with the unserialize implementation and garbage collection, which allows remote attackers to execute arbitrary code or cause a denial of service (use-after-free and application crash) via crafted serialized data containing a ZipArchive object.
