| Test ID: | 1.3.6.1.4.1.25623.1.0.704829 |
| Category: | Debian Local Security Checks |
| Title: | Debian: Security Advisory (DSA-4829-1) |
| Summary: | The remote host is missing an update for the Debian 'coturn' package(s) announced via the DSA-4829-1 advisory. |
| Description: | Summary: The remote host is missing an update for the Debian 'coturn' package(s) announced via the DSA-4829-1 advisory. Vulnerability Insight: A flaw was discovered in coturn, a TURN and STUN server for VoIP. By default coturn does not allow peers on the loopback addresses (127.x.x.x and ::1). A remote attacker can bypass the protection via a specially crafted request using a peer address of 0.0.0.0 and trick coturn in relaying to the loopback interface. If listening on IPv6 the loopback interface can also be reached by using either [::1] or [::] as the address. For the stable distribution (buster), this problem has been fixed in version 4.5.1.1-1.1+deb10u2. We recommend that you upgrade your coturn packages. For the detailed security status of coturn please refer to its security tracker page at: [link moved to references] Affected Software/OS: 'coturn' package(s) on Debian 10. Solution: Please install the updated package(s). CVSS Score: 6.4 CVSS Vector: AV:N/AC:L/Au:N/C:P/I:P/A:N |
