Novell Client NWSPOOL.DLL buffer overflow
| novell-nwspool-bo (30461) |  High Risk |
Description:
Novell Client for Windows is vulnerable to a buffer overflow, caused by improper bounds checking by the nwspool.dll library. By sending specially-crafted RPC requests to the EnumPrinters() or OpenPrinter() function, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the system to crash.
