The malware scan function in BullGuard Premium Protection 20.0.371.8 has a TOCTOU issue that enables a symbolic link attack, allowing privileged files to be deleted.
The product checks the state of a resource before using that resource, but the resource’s state can change between the check and the use in a way that invalidates the results of the check. This can cause the product to perform invalid actions when the resource is in an unexpected state.
