This update fixes the following security issues :

  - 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)

This update also fixes the following bug :

  - the rpc_call_async() function in the SUN Remote     Procedure Call (RPC) subsystem in the Linux kernel had a     reference counting bug. In certain situations, some     Network Lock Manager (NLM) messages may have triggered     this bug on NFSv2 and NFSv3 servers, leading to a kernel     panic (with 'kernel BUG at fs/lockd/host.c:[xxx]!'     logged to '/var/log/messages'). (BZ#612962)

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.

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-2010-2521: Multiple buffer overflows in fs/nfsd/nfs4xdr.c in the XDR implementation in the NFS server in the Linux kernel allowed remote attackers to cause a denial of service (panic) or possibly execute arbitrary code via a crafted NFSv4 compound WRITE request, related to the read_buf and nfsd4_decode_compound functions.

CVE-2010-2066: The mext_check_arguments function in fs/ext4/move_extent.c in the Linux kernel allowed local users to overwrite an append-only file via a MOVE_EXT ioctl call that specifies this file as a donor.

CVE-2010-2495: The pppol2tp_xmit function in drivers/net/pppol2tp.c in the L2TP implementation in the Linux kernel did not properly validate certain values associated with an interface, which allowed attackers to cause a denial of service (NULL pointer dereference and OOPS) or possibly have unspecified other impact via vectors related to a routing change.

CVE-2010-2071: The btrfs_xattr_set_acl function in fs/btrfs/acl.c in btrfs in the Linux kernel did not check file ownership before setting an ACL, which allowed local users to bypass file permissions by setting arbitrary ACLs, as demonstrated using setfacl.

CVE-2010-1641: The do_gfs2_set_flags function in fs/gfs2/file.c in the Linux kernel did not verify the ownership of a file, which allowed local users to bypass intended access restrictions via a SETFLAGS ioctl request.

CVE-2010-1087: The nfs_wait_on_request function in fs/nfs/pagelist.c in Linux kernel 2.6.x allowed attackers to cause a denial of service (Oops) via unknown vectors related to truncating a file and an operation that is not interruptible.

CVE-2010-1636: The btrfs_ioctl_clone function in fs/btrfs/ioctl.c in the btrfs functionality in the Linux kernel did not ensure that a cloned file descriptor has been opened for reading, which allowed local users to read sensitive information from a write-only file descriptor.

CVE-2010-1437: Race condition in the find_keyring_by_name function in security/keys/keyring.c in the Linux kernel allowed local users to cause a denial of service (memory corruption and system crash) or possibly have unspecified other impact via keyctl session commands that trigger access to a dead keyring that is undergoing deletion by the key_cleanup function.

CVE-2010-1148: The cifs_create function in fs/cifs/dir.c in the Linux kernel allowed local users to cause a denial of service (NULL pointer dereference and OOPS) or possibly have unspecified other impact via a NULL nameidata (aka nd) field in a POSIX file-creation request to a server that supports UNIX extensions.

CVE-2010-1162: The release_one_tty function in drivers/char/tty_io.c in the Linux kernel omitted certain required calls to the put_pid function, which has unspecified impact and local attack vectors.

CVE-2010-1146: The Linux kernel, when a ReiserFS filesystem exists, did not restrict read or write access to the .reiserfs_priv directory, which allowed local users to gain privileges by modifying (1) extended attributes or (2) ACLs, as demonstrated by deleting a file under .reiserfs_priv/xattrs/.

CVE-2009-4537: drivers/net/r8169.c in the r8169 driver in the Linux kernel did not properly check the size of an Ethernet frame that exceeds the MTU, which allowed remote attackers to (1) cause a denial of service (temporary network outage) via a packet with a crafted size, in conjunction with certain packets containing A characters and certain packets containing E characters; or (2) cause a denial of service (system crash) via a packet with a crafted size, in conjunction with certain packets containing '\0' characters, related to the value of the status register and erroneous behavior associated with the RxMaxSize register. NOTE: this vulnerability exists because of an incorrect fix for CVE-2009-1389.
