I think CAP_SYS_RAWIO is the wrong way to handle this, actually. This still leaves Wine able to use the 0 page, which is what needs to be avoided. ** Changed in: dosemu (Ubuntu) Status: New = Invalid ** Changed in: wine (Ubuntu) Status: Triaged = Invalid -- mmap_min_addr should

On all the machines that have wine installed cat /proc/sys/vm/mmap_min_addr returns 0. Shouldn't this bug be marked as high or critical as this seems to be exploitable? http://www.h-online.com/security/news/item/Root-exploit-for-Linux-kernel-published-742541.html -- mmap_min_addr should be

2009-07-20 Thread Kees Cook
Public bug reported: Binary package hint: dosemu I would like to see wine and dosemu using filesystem capabilties to temporarily grant themselves CAP_SYS_RAWIO during start up to map the memory below mmap_min_addr, instead of requiring that the entire running system have their mmap_min_addr
