-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Package : coturn Version : 4.2.1.2-1+deb8u1 CVE ID : CVE-2018-4056 CVE-2018-4058 CVE-2018-4059
Multiple vulnerabilities were discovered in coTURN, a TURN and STUN server for VoIP. CVE-2018-4056 An SQL injection vulnerability was discovered in the coTURN administrator web portal. As the administration web interface is shared with the production, it is unfortunately not possible to easily filter outside access and this security update completely disables the web interface. Users should use the local, command line interface instead. CVE-2018-4058 Default configuration enables unsafe loopback forwarding. A remote attacker with access to the TURN interface can use this vulnerability to gain access to services that should be local only. CVE-2018-4059 Default configuration uses an empty password for the local command line administration interface. An attacker with access to the local console (either a local attacker or a remote attacker taking advantage of CVE-2018-4058) could escalade privileges to administrator of the coTURN server. For Debian 8 "Jessie", these problems have been fixed in version 4.2.1.2-1+deb8u1. We recommend that you upgrade your coturn packages.
