> malicious people to bypass certain security restrictions.

> The vulnerability is caused due to a boundary error in the
> "snmpget()" function. This can be exploited to cause a stack-based
> buffer overflow via an overly long argument and execute arbitrary
> code, bypassing security restrictions like the "disable_functions"
> directive.
> 
> The vulnerability is reported in version 4.4.6. Other versions may
> also be affected.
> 
> SOLUTION:
> Grant only trusted users access to affected systems.
