"Updated kernel packages that fix multiple security issues and several
bugs are now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having
important security impact. Common Vulnerability Scoring System (CVSS)
base scores, which give detailed severity ratings, are available for
each vulnerability from the CVE links in the References section.

The kernel packages contain the Linux kernel, the core of any Linux
operating system.

This update fixes the following security issues :

* instances of unsafe sprintf() use were found in the Linux kernel
Bluetooth implementation. Creating a large number of Bluetooth L2CAP,
SCO, or RFCOMM sockets could result in arbitrary memory pages being
overwritten. A local, unprivileged user could use this flaw to cause a
kernel panic (denial of service) or escalate their privileges.
(CVE-2010-1084, Important)

* a flaw was found in the Xen hypervisor implementation when using the
Intel Itanium architecture, allowing guests to enter an unsupported
state. An unprivileged guest user could trigger this flaw by setting
the BE (Big Endian) bit of the Processor Status Register (PSR),
leading to the guest crashing (denial of service). (CVE-2010-2070,
Important)

* a flaw was found in the CIFSSMBWrite() function in the Linux kernel
Common Internet File System (CIFS) implementation. A remote attacker
could send a specially crafted SMB response packet to a target CIFS
client, resulting in a kernel panic (denial of service).
(CVE-2010-2248, Important)

* buffer overflow flaws were found in the Linux kernel's
implementation of the server-side External Data Representation (XDR)
for the Network File System (NFS) version 4. An attacker on the local
network could send a specially crafted large compound request to the
NFSv4 server, which could possibly result in a kernel panic (denial of
service) or, potentially, code execution. (CVE-2010-2521, Important)

* a flaw was found in the handling of the SWAPEXT IOCTL in the Linux
kernel XFS file system implementation. A local user could use this
flaw to read write-only files, that they do not own, on an XFS file
system. This could lead to unintended information disclosure.
(CVE-2010-2226, Moderate)

* a flaw was found in the dns_resolver upcall used by CIFS. A local,
unprivileged user could redirect a Microsoft Distributed File System
link to another IP address, tricking the client into mounting the
share from a server of the user's choosing. (CVE-2010-2524, Moderate)

* a missing check was found in the mext_check_arguments() function in
the ext4 file system code. A local user could use this flaw to cause
the MOVE_EXT IOCTL to overwrite the contents of an append-only file on
an ext4 file system, if they have write permissions for that file.
(CVE-2010-2066, Low)

Red Hat would like to thank Neil Brown for reporting CVE-2010-1084,
and Dan Rosenberg for reporting CVE-2010-2226 and CVE-2010-2066.

This update also fixes several bugs. Documentation for these bug fixes
will be available shortly from the Technical Notes document linked to
in the References.

Users should upgrade to these updated packages, which contain
backported patches to correct these issues. The system must be
rebooted for this update to take effect."

"Updated kernel packages that fix multiple security issues and several
bugs are now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having
important security impact. Common Vulnerability Scoring System (CVSS)
base scores, which give detailed severity ratings, are available for
each vulnerability from the CVE links in the References section.

The kernel packages contain the Linux kernel, the core of any Linux
operating system.

This update fixes the following security issues :

* instances of unsafe sprintf() use were found in the Linux kernel
Bluetooth implementation. Creating a large number of Bluetooth L2CAP,
SCO, or RFCOMM sockets could result in arbitrary memory pages being
overwritten. A local, unprivileged user could use this flaw to cause a
kernel panic (denial of service) or escalate their privileges.
(CVE-2010-1084, Important)

* a flaw was found in the Xen hypervisor implementation when using the
Intel Itanium architecture, allowing guests to enter an unsupported
state. An unprivileged guest user could trigger this flaw by setting
the BE (Big Endian) bit of the Processor Status Register (PSR),
leading to the guest crashing (denial of service). (CVE-2010-2070,
Important)

* a flaw was found in the CIFSSMBWrite() function in the Linux kernel
Common Internet File System (CIFS) implementation. A remote attacker
could send a specially crafted SMB response packet to a target CIFS
client, resulting in a kernel panic (denial of service).
(CVE-2010-2248, Important)

* buffer overflow flaws were found in the Linux kernel's
implementation of the server-side External Data Representation (XDR)
for the Network File System (NFS) version 4. An attacker on the local
network could send a specially crafted large compound request to the
NFSv4 server, which could possibly result in a kernel panic (denial of
service) or, potentially, code execution. (CVE-2010-2521, Important)

* a flaw was found in the handling of the SWAPEXT IOCTL in the Linux
kernel XFS file system implementation. A local user could use this
flaw to read write-only files, that they do not own, on an XFS file
system. This could lead to unintended information disclosure.
(CVE-2010-2226, Moderate)

* a flaw was found in the dns_resolver upcall used by CIFS. A local,
unprivileged user could redirect a Microsoft Distributed File System
link to another IP address, tricking the client into mounting the
share from a server of the user's choosing. (CVE-2010-2524, Moderate)

* a missing check was found in the mext_check_arguments() function in
the ext4 file system code. A local user could use this flaw to cause
the MOVE_EXT IOCTL to overwrite the contents of an append-only file on
an ext4 file system, if they have write permissions for that file.
(CVE-2010-2066, Low)

Red Hat would like to thank Neil Brown for reporting CVE-2010-1084,
and Dan Rosenberg for reporting CVE-2010-2226 and CVE-2010-2066.

This update also fixes several bugs. Documentation for these bug fixes
will be available shortly from the Technical Notes document linked to
in the References.

Users should upgrade to these updated packages, which contain
backported patches to correct these issues. The system must be
rebooted for this update to take effect."
