Novell Client for Windows username buffer overflow
| novell-client-username-bo (42359) |
Description:
Novell Client for Windows is vulnerable to a stack-based buffer overflow, caused by improper bounds checking by the LOGINW32.DLL module. By sending an overly long username in the "forgotten password" dialog and persuading a victim to click on the "forgot password" link, a local attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
