Samba nss_winbind.so.1 library gethostbyname and getipnodebyname buffer overflow
| samba-winbind-bo (32231) |  High Risk |
Description:
The Samba nss_winbind.so.1 library in Sun Solaris' winbind daemon is vulnerable to a buffer overflow, caused by improper bounds checking by the gethostbyname and getipnodebyname functions. By sending a specially-crafted name resolution query, a remote attacker could overflow a buffer and execute arbitrary code on the system.
