SMB: Samba NT Trans Reply Buffer Overflow
This signature detects attempts to exploit a known vulnerability against Samba 2.2.7a and earlier. Because Samba does not properly verify the NT Trans reply message, attackers can send a maliciously crafted Samba message to a Samba server and overflow the buffer.
Extended Description
Samba is prone to a buffer-overflow vulnerability when the 'smbd' service tries to reassemble specially crafted SMB/CIFS packets. An attacker can exploit this vulnerability by creating a specially formatted SMB/CIFS packet and sending it to a vulnerable Samba server. The overflow condition will be triggered and will cause smbd to overwrite sensitive areas of memory with attacker-supplied values. Note that the smbd service runs with root privileges.
