Samba < 3.0.30 receive_smb_raw Function Remote Buffer Overflow

High Nessus Plugin ID 32476


The remote Samba server may be affected by a buffer overflow vulnerability.


According to its banner, the version of the Samba server on the remote host is reportedly affected by a boundary error in 'nmbd' within the 'receive_smb_raw' function in 'lib/util_sock.c' when parsing SMB packets received in a client context. By sending specially crafted packets to an 'nmbd' server configured as a local or domain master browser, an attacker can leverage this issue to produce a heap-based buffer overflow and execute arbitrary code with system privileges.

Note that Nessus has not actually tried to exploit this issue, verify the remote 'nmbd' server's configuration, or determine if the fix has been applied.


Upgrade to Samba version 3.0.30 or later or apply the patch referenced in the project's advisory.
