medium Nessus Plugin ID 43087

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

Robin Park and Dmitri Vinokurov discovered a logic error in ntpd. A remote attacker could send a crafted NTP mode 7 packet with a spoofed IP address of an affected server and cause a denial of service via CPU and disk resource consumption.

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.
