Details

Updated kernel packages that fix a number of security issues as well as
other bugs are now available for Red Hat Enterprise Linux 2.1 (32 bit
architectures)

This security advisory has been rated as having important security impact
by the Red Hat Security Response Team.

The Linux kernel handles the basic functions of the operating system.

These new kernel packages contain fixes for the security issues described
below:

* a flaw in the USB devio handling of device removal that allowed a local
user to cause a denial of service (crash) (CVE-2005-3055, moderate)

* a flaw in ROSE due to missing verification of the ndigis argument of new
routes (CVE-2005-3273, moderate)

* an info leak on AMD-based x86 systems that allowed a local user to
retrieve the floating point exception state of a process run by a different
user (CVE-2006-1056, important)

* a minor info leak in socket name handling in the network code
(CVE-2006-1342, low)

* a minor info leak in socket option handling in the network code
(CVE-2006-1343, low)

* a directory traversal vulnerability in smbfs that allowed a local user to
escape chroot restrictions for an SMB-mounted filesystem via "..\\"
sequences (CVE-2006-1864, moderate)

* a flaw in the mprotect system call that allowed to give write permission
to a readonly attachment of shared memory (CVE-2006-2071, moderate)

A performance bug in the NFS implementation that caused clients to
frequently pause when sending TCP segments during heavy write loads was
also addressed.

All Red Hat Enterprise Linux 2.1 users are advised to upgrade their kernels
to these updated packages, which contain backported fixes to correct these
issues.
