Packages

Details
As written in the advisory (Markdown source, shown as plain text).
In matrix-sdk-base before 0.14.1, calling the `RoomMember::normalized_power_level()` method can cause a panic if a room member has a power level of `Int::Min`.
### Patches
The issue is fixed in matrix-sdk-base 0.14.1.
### Workarounds
The affected method isn’t used internally, so avoiding calling `RoomMember::normalized_power_level()` prevents the panic.
