Summary
Local SID/Name translation bug can result in user privilege elevation.
Insight
Insight
When translating SIDs to/from names using Samba local list of user and group accounts, a logic error in the smbd daemon's internal security stack may result in a transition to the root user id rather than the non-root user. The user is then able to temporarily issue SMB/CIFS protocol operations as the root user. This window of opportunity may allow the attacker to establish additional means of gaining root access to the server.
Affected Software
Affected Software
Samba versions 3.0.23d through 3.0.25pre2.
