> DESCRIPTION:
> Eugene Teo has reported a vulnerability in the Linux Kernel, which
> potentially can be exploited by malicious, local users to gain
> escalated privileges.
> 
> The vulnerability is caused due to an integer overflow within the
> "get_fdb_entries()" function in net/bridge/br_ioctl.c. This can be
> exploited to cause a buffer overflow via specially crafted ioctl()
> requests.
> 
> Successful exploitation may allow the execution of arbitrary code
> with escalated privileges.
> 
> SOLUTION:
> Update to version 2.6.18.4 or 2.6.19.
> 
> PROVIDED AND/OR DISCOVERED BY:
> Reported by Eugene Teo, further research by a1rsupp1y.
