recent mass Solaris and Linux attacks

Short blurb:  Lots of academic, research and High Performance computers have been compromised.  
Looks to be due to kernels not being updated. 

 "Local user accounts are escalated to root privileges by triggering a variety of local exploits, 
including the do_brk() and mremap() exploits on Linux and the sadmind, arbitrary kernel loading 
modules and passwd vulnerabilities on Solaris"

If you manage machines such as these, have you updated your kernel beyond 2.4.22?
