CVE-2014-1916

Published: 8 February 2014

The (1) opus_packet_get_nb_frames and (2) opus_packet_get_samples_per_frame functions in the client in MumbleKit before commit fd190328a9b24d37382b269a5674b0c0c7a7e36d and Mumble for iOS 1.1 through 1.2.2 do not properly check the return value of the copyDataBlock method, which allow remote attackers to cause a denial of service (NULL pointer dereference and crash) via a crafted length prefix value in an Opus voice packet.

Notes

this is for MumbleKit, not Mumble. MumbleKit is a client framework
for iOS and Mac OS X. Code not present in mumble
