Impact
Malformed resource identifiers may render the iOS Wire Client completely unusable by causing it to repeatedly crash on launch.
These malformed resource identifiers can be generated and sent between Wire users.
The root cause lies in wireapp/wire-ios-transport, where code responsible for removing sensible tokens before logging may fail and lead to a crash (Swift exception) of the application.
This causes undesirable behavior, however the (greater) Wire system is still functional.
Patches
Workarounds
There is no workaround available, but users may use other Wire clients (such as the web app) to continue using Wire.
