Samba SMB/CIFS packet fragment re-assembly code buffer overflow

samba-smbcifs-smbd-bo (11550)

High Risk

Description:

Samba is vulnerable to a buffer overflow in the SMB/CIFS packet fragment re-assembly code in the smbd daemon. A remote attacker could connect to TCP port 139 or 445 and send a specially-crafted SMB/CIFS packet to overflow a buffer to overwrite memory, and possibly execute arbitrary code on the system with root privileges.

Consequences:

Gain Access
