CVE-2014-0044: Light Speed Gaming Mumble

Medium severity, CVSS 5.0. EPSS: 2.4% chance of exploitation in the next 30 days.

The opus_packet_get_samples_per_frame function in client in Mumble 1.2.4 and the 1.2.3 pre-release snapshots allows remote attackers to cause a denial of service (crash) via a crafted length prefix value, which triggers a NULL pointer dereference or a heap-based buffer over-read (aka "out-of-bounds array access").
