Package : mumble
Version : 1.2.8-2+deb8u1
CVE ID : CVE-2018-20743
Debian Bug : 919249

It has been found that the mumble-server mishandles multiple
concurrent requests that are persisted in the database, which allows
remote attackers to cause a denial of service (daemon hang or crash)
via a message flood. With the new security update a rate limiter is
added with Leaky-Bucket algorithm.

For Debian 8 "Jessie", this problem has been fixed in version
1.2.8-2+deb8u1.

We recommend that you upgrade your mumble packages.
