DESCRIPTION:
rgod has reported a vulnerability in PHP4, which can be exploited by
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.
