Description: 
 The scm_send function in the scm layer for Linux kernel 2.4.x up to 2.4.28,
 and 2.6.x up to 2.6.9, allows local users to cause a denial of service (system
 hang) via crafted auxiliary messages that are passed to the sendmsg function,
 which causes a deadlock condition.
Notes: 
 dannf> 2.4.27 has a reference to CVE-2004-1016 in the changelog, but it looks
        like it referred to the wrong issue - our 2.4.27 may still be
        vulnerable.
 dannf> on second review, those patches look correct
