Description Mark J. Cox 2004-06-15 13:49:11 UTC

Last week a flaw was published in the Linux kernel.  The issue affects
Linux kernel 2.4 and 2.6 for x86 and allows local users to cause a
denial of service (system crash) with a certain sequence of fsave and
frstor instructions.  Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2004-0554 to this issue.

Although this issue is reported as affecting 2.4.2x the flawed code
exists in other 2.4 release too, so this bug is for tracking the fix
for Red Hat Enterprise Linux 2.1
