The following security errata for Scientific Linux 3.0.1 are now available in /export/linux/scientific/301/i386/errata/SL/RPMS/ on linux21.fnal.gov The default yum-conf does NOT install the kernel errata. You need to use either yum or apt to do that. There are more enhancement and bug fix errata recently released by the "vendor". After a short test period as part of /export/linux/scientific/30rolling/i386/ they will be added to the errata for Scientific Linux 3.0.1 . This batch of errata are for security issues. kernel-2.4.21-15.EL.athlon.rpm kernel-2.4.21-15.EL.i686.rpm kernel-BOOT-2.4.21-15.EL.i386.rpm kernel-doc-2.4.21-15.EL.i386.rpm kernel-hugemem-2.4.21-15.EL.i686.rpm kernel-hugemem-unsupported-2.4.21-15.EL.i686.rpm kernel-smp-2.4.21-15.EL.athlon.rpm kernel-smp-2.4.21-15.EL.i686.rpm kernel-smp-unsupported-2.4.21-15.EL.athlon.rpm kernel-smp-unsupported-2.4.21-15.EL.i686.rpm kernel-source-2.4.21-15.EL.i386.rpm kernel-unsupported-2.4.21-15.EL.athlon.rpm kernel-unsupported-2.4.21-15.EL.i686.rpm openafs-kernel-1.2.10-SL2421.15.1.i386.rpm kernel-utils-2.4-8.37.3.i386.rpm kdelibs-3.1.3-6.4.i386.rpm kdelibs-devel-3.1.3-6.4.i386.rpm ipsec-tools-0.2.5-0.4.i386.rpm initscripts-7.31.13.EL-1.i386.rpm cvs-1.11.2-22.i386.rpm -Connie Sieh
