Description Vincent Danen 2014-02-05 18:43:42 UTC 
A denial of service flaw, with possible (but unconfirmed) arbitrary code execution, was reported [1] in Mumble:


A malformed Opus voice packet sent to a Mumble client could trigger a heap-based buffer overflow. This causes a client crash (Denial of Service) and can potentially be used to execute arbitrary code, though this is unconfirmed.

This issue can be triggered remotely by an entity participating in a Mumble voice chat.

This has been corrected in upstream version 1.2.5 [2].
