Title: Samba 'call_trans2open' Remote Buffer Overflow Vulnerability
Severity: CRITICAL
Description:
Samba is a freely available file and printer sharing application maintained and developed by the Samba Development Team. Samba allows file and printer sharing between operating systems on the Unix and Microsoft platforms. The Samba daemon is typically run with super user privileges.
A buffer overflow vulnerability has been reported for Samba that could allow an anonymous remote attacker to execute arbitrary code.
The vulnerability occurs in the 'call_trans2open()' function when copying data into a 1024 byte static buffer. Sufficient bounds checking is not performed when a call to the 'Strncpy()' function is invoked. The length argument supplied to 'Strncpy()' is exactly the length of the user-supplied data. As a result, an attacker could exploit this vulnerability by sending data in excess of 1024 bytes.
Successful exploitation of this vulnerability could allow an anonymous attacker to overwrite sensitive stack variables, including the 'open_trans2open()' functions' saved return address. The ability to influence sensitive memory could be leveraged by the attacker to execute arbitrary code with the privileges of the Samba server process.
