NVD Description

Note: Versions mentioned in the description apply only to the upstream php7.2 package and not the php7.2 package as distributed by Ubuntu.

ext/standard/var.c in PHP 5.x through 7.1.24 on Windows allows attackers to cause a denial of service (NULL pointer dereference and application crash) because com and com_safearray_proxy return NULL in com_properties_get in ext/com_dotnet/com_handlers.c, as demonstrated by a serialize call on COM("WScript.Shell").
