New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it is different from CVSS.
VPR Score: 5.9
Synopsis
The remote Ubuntu host is missing one or more security-related patches.Description
It was discovered that the libraries handling RPCSEC_GSS did not correctly validate the size of certain packet structures. An unauthenticated remote user could send a specially crafted request and execute arbitrary code with root privileges.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.
