Medium Nessus Plugin ID 83252
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionNick Sampanis discovered that Dnsmasq incorrectly handled certain malformed DNS requests. A remote attacker could use this issue to cause Dnsmasq to crash, resulting in a denial of service, or possibly obtain sensitive information.
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpdate the affected dnsmasq, dnsmasq-base and / or dnsmasq-utils packages.
