CVE-2016-4073
CriticalSummary
Multiple integer overflows in the mbfl_strcut function in PHP before 5.5.34, 5.6.x before 5.6.20, and 7.x before 7.0.5 may allow remote attackers to cause application crashes or potentially execute arbitrary code via a crafted mb_strcut call.
Risk Assessment
This vulnerability could lead to service outages and allow attackers to execute unauthorized code, posing a serious threat to the security of the application and the organization's data.
Recommendation
It is recommended to update PHP to the latest version to mitigate this vulnerability and conduct an application audit to identify potential attack vectors.

In node-opcua (an OPC UA implementation for TypeScript and Node.js), versions 2.42.0 through 2.180.0 do not honor namespace-level access control configured via setDefaultRolePermissions for nodes without explicit per-node permissions. SessionContext.getApplicableRolePermissions reads a missing or null value instead of the configured namespace field, and the null result is treated permissively. As a result, an anonymous network client can write variables or call bound methods when an operator relied on restrictive namespace defaults.
