| Vetor | AV:N/AC:L/Au:N/C:N/I:N/A:P |
Name of the Vulnerable Software and Affected Versions
Dnsmasq versions prior to 2.63test1
Description
The issue allows remote attackers to cause a denial of service, specifically through traffic amplification, by sending a spoofed DNS query. This occurs when Dnsmasq is used with certain configurations in libvirt and responds to requests from prohibited interfaces.
Recommendations
For versions prior to 2.63test1, update to version 2.63test1 or later to resolve the issue. As a temporary workaround, consider restricting access to the DNS service to minimize the risk of exploitation.
