TITLE

D-Link DWL-G132 Wireless adapter A5AGU.SYS Vulnerable to stack-based buffer overflow

DESCRIPTION

Stack-based buffer overflow in A5AGU.SYS 1.0.1.41 for the D-Link DWL-G132 wireless adapter allows remote attackers to execute arbitrary code via a 802.11 beacon request with a long Rates information element (IE). D-LINK DWL-G132 is a high performance 802.11g wireless network card.  D-Link DWL-G132 wireless network card A5AGU.SYS driver has a stack overflow vulnerability. A remote attacker may use this vulnerability to execute arbitrary instructions on the user's machine. Because the overflow is triggered by a beacon frame, all network cards in the attack range are affected. The D-Link Wireless Device Driver for DWL-G132 devices is prone to a stack-based buffer-overflow vulnerability because the driver fails to properly bounds-check user-supplied data before copying it into an insufficiently sized memory buffer. Exploiting this issue allows attackers to execute arbitrary machine code in the context of the kernel hosting the vulnerable driver. Failed attempts will likely crash the kernel, resulting in denial-of-service conditions. The ASAGU.SYS driver is primarily used on the Microsoft Window operating system. Note, however, that Linux and BSD machines using the 'ndiswrapper' tool should determine if they are using a vulnerable instance of the driver. Note also that this vulnerability can be exploited only when an attacker is within the range of broadcast of 802.11 wireless connections. Version 1.0.1.41 of the ASAGU.SYS driver is reported vulnerable; other versions may also be affected. ---------------------------------------------------------------------- To improve our services to our customers, we have made a number of additions to the Secunia Advisories and have started translating the advisories to German.
