Package : rt2570
Vulnerability : integer overflow
Problem type : remote
Debian-specific: no
CVE Id(s) : CVE-2009-0282

It was discovered that an integer overflow in the "Probe Request" packet
parser of the Ralinktech wireless drivers might lead to remote denial of
service or the execution of arbitrary code.

Please note that you need to rebuild your driver from the source
package in order to set this update into effect. Detailed
instructions can be found in /usr/share/doc/rt2570-source/README.Debian

For the stable distribution (etch), this problem has been fixed in

We recommend that you upgrade your rt2570 package.
