TP-Link Wi-Fi extender remote code execution vulnerability analysis-vulnerability warning-the black bar safety net

WiFi extender can enlarge the WiFi signal, mainly used for large or multi-storey residential, and the router signal can not cover the family's case. The extender's principle is from the main router to get a WiFi signal, and broadcast channel other WiFi signal weak or no signal area. IBM X-Force...

iOS < 12.2 / macOS < 10.14.4 XNU - pidversion Increment During execve is Unsafe

Privileged IPC services in userspace often have to verify the security context of their client processes such as whether the client is sandboxed, has a specific entitlement, or is signed by some code signing authority. This, in turn, requires a way to identify a client process. If PIDs are used f...
