Subject: [FD] Xamarin Studio for Mac API documentation update affected by

Xamarin Studio for Mac API documentation update affected by local
privilege escalation

Yorick Koster, April 2017

Abstract

Xamarin Studio is an Integrated Development Environment (IDE) used to
create iOS, Mac and Android applications. Xamarin Studio supports
developments in C# and F# (by default). The API documentation update
mechanism of Xamarin Studio for Mac is installed as setuid root. This
update mechanism contains several flaws that could be leveraged by a
local attacker to gain elevated (root) privileges.
