Description Eugene Teo (Security Response) 2011-04-13 01:40:10 UTC

The Linux kernel automatically evaluates partition tables of storage devices. The code for evaluating EFI GUID partitions (in fs/partitions/efi.c) contains a bug that causes a kernel oops on certain corrupted GUID partition tables.

Statement:

This issue affects the versions of Linux kernel as shipped with Red Hat
Enterprise Linux 4, 5, 6, and Red Hat Enterprise MRG. This has been addressed in Red Hat Enterprise Linux 5, 6 and Red Hat Enterprise MRG via https://rhn.redhat.com/errata/RHSA-2011-0833.html, https://rhn.redhat.com/errata/RHSA-2011-1465.html, and https://rhn.redhat.com/errata/RHSA-2011-1253.html. Red Hat Enterprise Linux 4 is now in Production 3 of the maintenance life-cycle, https://access.redhat.com/support/policy/updates/errata/, therefore the fix for this issue is not currently planned to be included in the future updates.
