Description:   Opened: 2007-10-23 18:45 0000 
The xenbaked daemon and xenmon utility communicate via a mmap'ed
 shared file. Since this file is located in /tmp, unprivileged users
 can cause arbitrary files to be truncated by creating a symlink from
 the well-known /tmp filename to e.g., /etc/passwd.

 The fix is to place the shared file in a directory to which only root
 should have access (in this case /var/run/).

 This bug was reported, and the fix suggested, by Steve Kemp
 <skx@debian.org>. Thanks!
