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's different from CVSS.

VPR Score: 5.9


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


Marcus Meissner discovered that the winbind plugin of pppd does not check the result of the setuid() call. On systems that configure PAM limits for the maximum number of user processes and enable the winbind plugin, a local attacker could exploit this to execute the winbind NTLM authentication helper as root. Depending on the local winbind configuration, this could potentially lead to privilege escalation.

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 ppp, ppp-dev and / or ppp-udeb packages.
