The security advisory RHSA-2005:472-05 says:
"These new kernel packages contain fixes for the three security issues
described below as well as an important fix for a problem that could
lead to data corruption on x86-architecture SMP systems with greater
than 4GB of memory through heavy usage of multi-threaded applications."
According to my own records and RHN, all of my machines (WS and AS) are
running kernel 2.4.21-32.EL, many (WS and AS) are running 2.4.21-32.ELsmp.
One AS machine has 4GB of RAM, the remainder have between 512MB and 2GB of
RAM.
All (bar one) were kickstarted from RHEL3 u4 kickstart points and have
been through the 2.4.21-27.0.2.EL -> 2.4.21-27.0.4.EL -> 2.4.21-32.EL
kernel upgrade path. All are fully up to date with regard to up2date
and the RHN. None of these machines apparently require that
RHSA-2005:472-05 be applied.
The remaining one AS machine was kickstarted very recently from a RHEL3 u5
kickstart point directly to kernel 2.4.21-32.ELsmp. Only this machine is
listed in RHN as requiring the upgrade to 2.4.21-32.0.1.EL (the above
RHSA-2005:472-05). There's an additional RHSA-2005:413-04 regarding
ImageMagick which also only seems to apply to this machine and none of the
others but I'm not so concerned about that.
This single machine was kickstarted in an identical manner (other than
using a u5 rather than a u4 kickstart set) to another machine, runs on
identical hardware and has all the same RPMs on. That other machine
doesn't require either errata. I don't get it.
Does anyone know what's going on?
