Ubuntu 6.06 LTS / 7.10 / 8.04 LTS / 8.10 : ntp vulnerability (USN-705-1)

Medium Nessus Plugin ID 37876


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


It was discovered that NTP did not properly perform signature verification. A remote attacker could exploit this to bypass certificate validation via a malformed SSL/TLS signature.

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.


Update the affected packages.
