DLA-2271-1 coturn -- LTS security update
- Date Reported:
- 01 Jul 2020
- Affected Packages:
- Security database references:
- In Mitre's CVE dictionary: CVE-2020-4067.
- More information:
In coturn before version 18.104.22.168, there is an issue whereby STUN/TURN response buffer is not initialized properly. There is a leak of information between different client connections. One client (an attacker) could use their connection to intelligently query coturn to get interesting bytes in the padding bytes from the connection of another client.
For Debian 8
Jessie, this problem has been fixed in version 22.214.171.124-1+deb8u2.
We recommend that you upgrade your coturn packages.
