Description Sune Kloppenborg Jeppesen (RETIRED) gentoo-dev 2007-10-23 18:45:06 UTC 
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!
