Updated kernel packages that fix multiple security issues and several bugs are now available for Red Hat Enterprise Linux 6.

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 :

CVE-2010-2492: Buffer overflow in the ecryptfs_uid_hash macro in fs/ecryptfs/messaging.c in the eCryptfs subsystem in the Linux kernel might have allowed local users to gain privileges or cause a denial of service (system crash) via unspecified vectors.

CVE-2010-2248: fs/cifs/cifssmb.c in the CIFS implementation in the Linux kernel allowed remote attackers to cause a denial of service (panic) via an SMB response packet with an invalid CountHigh value, as demonstrated by a response from an OS/2 server, related to the CIFSSMBWrite and CIFSSMBWrite2 functions.

CVE-2010-2803: The drm_ioctl function in drivers/gpu/drm/drm_drv.c in the Direct Rendering Manager (DRM) subsystem in the Linux kernel allowed local users to obtain potentially sensitive information from kernel memory by requesting a large memory-allocation amount.

CVE-2010-2478: A potential buffer overflow in the ETHTOOL_GRXCLSRLALL ethtool code was fixed which could be used by local attackers to crash the kernel or potentially execute code.

CVE-2010-2524: The DNS resolution functionality in the CIFS implementation in the Linux kernel, when CONFIG_CIFS_DFS_UPCALL is enabled, relies on a user's keyring for the dns_resolver upcall in the cifs.upcall userspace helper, which allowed local users to spoof the results of DNS queries and perform arbitrary CIFS mounts via vectors involving an add_key call, related to a 'cache stuffing' issue and MS-DFS referrals.

CVE-2010-2798: The gfs2_dirent_find_space function in fs/gfs2/dir.c in the Linux kernel used an incorrect size value in calculations associated with sentinel directory entries, which allowed local users to cause a denial of service (NULL pointer dereference and panic) and possibly have unspecified other impact by renaming a file in a GFS2 filesystem, related to the gfs2_rename function in fs/gfs2/ops_inode.c.

CVE-2010-2537: The BTRFS_IOC_CLONE and BTRFS_IOC_CLONE_RANGE ioctls allowed a local user to overwrite append-only files.

CVE-2010-2538: The BTRFS_IOC_CLONE_RANGE ioctl was subject to an integer overflow in specifying offsets to copy from a file, which potentially allowed a local user to read sensitive filesystem data.

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.
