Quoting from http://rhn.redhat.com/errata/RHSA-2005-294.html:
A flaw in offset handling in the xattr file system code backported to
Red Hat Enterprise Linux 3 was fixed. On 64-bit systems, a user who
can access an ext3 extended-attribute-enabled file system could cause
a denial of service (system crash). This issue is rated as having a
moderate security impact (CAN-2005-0757).
I couldn't find further information on whether this is already fixed
in 2.4.27, do you have further information?
Cheers,
Moritz
