A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 15.04 - Ubuntu 14.10 - Ubuntu 14.04 LTS - Ubuntu 12.04 LTS
Summary:
Dnsmasq could be made to crash or expose sensitive information if it received specially crafted network traffic.
Software Description: - dnsmasq: Small caching DNS proxy and DHCP/TFTP server
Details:
