 Hi there,
Take a look to http://seclists.org/oss-sec/2013/q1/204
Please, use CVE-2013-0241 to refer this issue.
The Debian package in unstable looks affected. Can you check if the stable 
 or 
 testings are affected too?
I checked the patch, it modified following function: 

  qxl_handle_oom
  qxl_allocnf
  setup_slot
  qxl_surface_cache_create_primary
  download_box

qxl_allocnf exist in qxl 0.0.12, but it have not use ioport_write 
function, other function don't exist in qxl 0.0.12. 

Could you please check wheather this bug affect qxl in squeeze ? 

Thanks and Regards,

Would you like to check xserver-xorg-video-qxl 0.0.17 is 
affected?

bug is fixed in commit 30b4b72cdbdf9f0e92a8d1c4e01779f60f15a741, 
which is included in 0.0.17.

I'm backport this patch to 0.0.12, I'll let you know when 
it is ready. 

Thanks and Regards,
