The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version.

branch but not yet published.
derive-com-impl is a Procedural macros to help implement COM interfaces from Rust.
Affected versions of this package are vulnerable to NULL Pointer Dereference. It provides a faulty implementation of the IUnknown::QueryInterface
method. QueryInterface
implementation must call IUnknown::AddRef
before returning the pointer, as describe in this documentation: https://docs.microsoft.com/en-us/windows/win32/api/unknwn/nf-unknwn-iunknown-queryinterface(refiid_void) As it is not incrementing the refcount as expected, the following calls to IUnknown::Release
method will cause WMI to drop reference to the interface, and can lead to invalid reference.
There is no simple workaround, as you can't know how many time QueryInterface
will be called. The only way to quick fix this is to use the macro expanded version of the code and modify the QueryInterface
method to add the AddRef
call yourself.
