TITLE:
Broadcom NetXtreme ASF Buffer Overflow Vulnerability

SECUNIA ADVISORY ID:
SA39107

VERIFY ADVISORY:
http://secunia.com/advisories/39107/

DESCRIPTION:
A vulnerability has been reported in various Broadcom NetXtreme
devices, which can be exploited by malicious people to potentially
compromise a vulnerable device.

The vulnerability is caused due to an error when processing certain
ASF version 2.0 RAKP Message 1 packets, which can be exploited to
cause a buffer overflow by sending a specially crafted packet.

Successful exploitation requires that Remote Management and Control
Protocol (RMCP) over the RMCP Security-Extensions Protocol (RSP)
manageability is enabled (generally disabled by default).

The vulnerability is reported in the following devices and firmware
versions:
* BCM5751, BCM5752, BCM5753, BCM5754, BCM5755, BCM5756, BCM5764, and
BCM5787 firmware version 8.04
* BCM57760 firmware version 8.07
* BCM5761 firmware version 1.24.0.9

SOLUTION:
Reportedly, Broadcom NetXtreme 14.0 software released to OEMs
contains a corrected firmware version.

Disable the management firmware or Secure ASF (RSP) support.

PROVIDED AND/OR DISCOVERED BY:
Loïc Duflot and Yves-Alexis Perez of the French Agence Nationale de
la Sécurité des Systèmes d’Information (ANSSI)
