Discussion

Samba SID Names Local Privilege Escalation Vulnerability

Samba is prone to a local privilege-escalation vulnerability due to a logic error in the 'smbd' daemon's internal security stack.

An attacker can exploit this issue to temporarily perform SMB/CIFS operations with superuser privileges. The attacker may leverage this issue to gain superuser access to the server.

Samba 3.0.23d through 3.0.25pre2 are vulnerable.
