- Date Reported:
- 06 Feb 2019
- Affected Packages:
- Security database references:
- In the Debian bugtracking system: Bug 919249.
In Mitre's CVE dictionary: CVE-2018-20743.
- More information:
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.
