Samba and Samba-TNG call_trans2open() function buffer overflow
| samba-calltrans2open-bo (11726) |  High Risk |
Description:
Samba is vulnerable to a buffer overflow in the call_trans2open() function. By supplying a string containing more than 1024 bytes to the pname variable, a remote attacker could overflow a buffer and gain root access on the system.
