Medium Nessus Plugin ID 108335
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionBjorn Baumbach discovered that Samba incorrectly validated permissions when changing account passwords via LDAP. An authenticated attacker could use this issue to change the password of other users, including administrators, and perform actions as those users.
It was discovered that Samba incorrectly validated inputs to the RPC spoolss service. An authenticated attacker could use this issue to cause the service to crash, resulting in a denial of service.
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.
