Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

This security update of the openSUSE 11.1 kernel fixes 3 critical security issues.

Following security bugs were fixed: CVE-2010-3301: Mismatch between 32bit and 64bit register usage in the system call entry path could be used by local attackers to gain root privileges. This problem only affects x86_64 kernels.

CVE-2010-3081: Incorrect buffer handling in the biarch-compat buffer handling could be used by local attackers to gain root privileges.
This problem affects foremost x86_64, or potentially other biarch platforms, like PowerPC and S390x.

CVE-2010-2959: Integer overflow in net/can/bcm.c in the Controller Area Network (CAN) implementation in the Linux kernel allowed attackers to execute arbitrary code or cause a denial of service (system crash) via crafted CAN traffic.

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2010:0842 advisory.

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

    This update fixes the following security issues:

    * Missing sanity checks in the Intel i915 driver in the Linux kernel could     allow a local, unprivileged user to escalate their privileges.
    (CVE-2010-2962, Important)

    * compat_alloc_user_space() in the Linux kernel 32/64-bit compatibility     layer implementation was missing sanity checks. This function could be     abused in other areas of the Linux kernel if its length argument can be     controlled from user-space. On 64-bit systems, a local, unprivileged user     could use this flaw to escalate their privileges. (CVE-2010-3081,     Important)

    * A buffer overflow flaw in niu_get_ethtool_tcam_all() in the niu Ethernet     driver in the Linux kernel, could allow a local user to cause a denial of     service or escalate their privileges. (CVE-2010-3084, Important)

    * A flaw in the IA32 system call emulation provided in 64-bit Linux kernels     could allow a local user to escalate their privileges. (CVE-2010-3301,     Important)

    * A flaw in sctp_packet_config() in the Linux kernel's Stream Control     Transmission Protocol (SCTP) implementation could allow a remote attacker     to cause a denial of service. (CVE-2010-3432, Important)

    * A missing integer overflow check in snd_ctl_new() in the Linux kernel's     sound subsystem could allow a local, unprivileged user on a 32-bit system     to cause a denial of service or escalate their privileges. (CVE-2010-3442,     Important)

    * A flaw was found in sctp_auth_asoc_get_hmac() in the Linux kernel's SCTP     implementation. When iterating through the hmac_ids array, it did not reset     the last id element if it was out of range. This could allow a remote     attacker to cause a denial of service. (CVE-2010-3705, Important)

    * A function in the Linux kernel's Reliable Datagram Sockets (RDS) protocol     implementation was missing sanity checks, which could allow a local,     unprivileged user to escalate their privileges. (CVE-2010-3904, Important)

    * A flaw in drm_ioctl() in the Linux kernel's Direct Rendering Manager     (DRM) implementation could allow a local, unprivileged user to cause an     information leak. (CVE-2010-2803, Moderate)

    * It was found that wireless drivers might not always clear allocated     buffers when handling a driver-specific IOCTL information request. A local     user could trigger this flaw to cause an information leak. (CVE-2010-2955,     Moderate)

    * A NULL pointer dereference flaw in ftrace_regex_lseek() in the Linux     kernel's ftrace implementation could allow a local, unprivileged user to     cause a denial of service. Note: The debugfs file system must be mounted     locally to exploit this issue. It is not mounted by default.
    (CVE-2010-3079, Moderate)

    * A flaw in the Linux kernel's packet writing driver could be triggered     via the PKT_CTRL_CMD_STATUS IOCTL request, possibly allowing a local,     unprivileged user with access to /dev/pktcdvd/control to cause an     information leak. Note: By default, only users in the cdrom group have     access to /dev/pktcdvd/control. (CVE-2010-3437, Moderate)

    * A flaw was found in the way KVM (Kernel-based Virtual Machine) handled     the reloading of fs and gs segment registers when they had invalid     selectors. A privileged host user with access to /dev/kvm could use this     flaw to crash the host. (CVE-2010-3698, Moderate)

(CVE-2010-0622)

The kvm_arch_vcpu_ioctl_set_sregs function in the KVM in Linux kernel 2.6 before 2.6.30, when running on x86 systems, does not validate the page table root in a KVM_SET_SREGS call, which allows local users to cause a denial of service (crash or hang) via a crafted cr3 value, which triggers a NULL pointer dereference in the gfn_to_rmap function.
(CVE-2009-2287)

The handle_dr function in arch/x86/kvm/vmx.c in the KVM subsystem in the Linux kernel before 2.6.31.1 does not properly verify the Current Privilege Level (CPL) before accessing a debug register, which allows guest OS users to cause a denial of service (trap) on the host OS via a crafted application. (CVE-2009-3722)

The ext4_decode_error function in fs/ext4/super.c in the ext4 filesystem in the Linux kernel before 2.6.32 allows user-assisted remote attackers to cause a denial of service (NULL pointer dereference), and possibly have unspecified other impact, via a crafted read-only filesystem that lacks a journal. (CVE-2009-4308)

The eisa_eeprom_read function in the parisc isa-eeprom component (drivers/parisc/eisa_eeprom.c) in the Linux kernel before 2.6.31-rc6 allows local users to access restricted memory via a negative ppos argument, which bypasses a check that assumes that ppos is positive and causes an out-of-bounds read in the readb function.
(CVE-2009-2846)

Multiple buffer overflows in fs/nfsd/nfs4xdr.c in the XDR implementation in the NFS server in the Linux kernel before 2.6.34-rc6 allow 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-2010-2521)

mm/shmem.c in the Linux kernel before 2.6.28-rc8, when strict overcommit is enabled and CONFIG_SECURITY is disabled, does not properly handle the export of shmemfs objects by knfsd, which allows attackers to cause a denial of service (NULL pointer dereference and knfsd crash) or possibly have unspecified other impact via unknown vectors. NOTE: this vulnerability exists because of an incomplete fix for CVE-2010-1643. (CVE-2008-7256)

The release_one_tty function in drivers/char/tty_io.c in the Linux kernel before 2.6.34-rc4 omits certain required calls to the put_pid function, which has unspecified impact and local attack vectors.
(CVE-2010-1162)

mm/shmem.c in the Linux kernel before 2.6.28-rc3, when strict overcommit is enabled, does not properly handle the export of shmemfs objects by knfsd, which allows attackers to cause a denial of service (NULL pointer dereference and knfsd crash) or possibly have unspecified other impact via unknown vectors. (CVE-2010-1643)

The sctp_process_unk_param function in net/sctp/sm_make_chunk.c in the Linux kernel 2.6.33.3 and earlier, when SCTP is enabled, allows remote attackers to cause a denial of service (system crash) via an SCTPChunkInit packet containing multiple invalid parameters that require a large amount of error data. (CVE-2010-1173)

The Transparent Inter-Process Communication (TIPC) functionality in Linux kernel 2.6.16-rc1 through 2.6.33, and possibly other versions, allows local users to cause a denial of service (kernel OOPS) by sending datagrams through AF_TIPC before entering network mode, which triggers a NULL pointer dereference. (CVE-2010-1187)

The sctp_process_unk_param function in net/sctp/sm_make_chunk.c in the Linux kernel 2.6.33.3 and earlier, when SCTP is enabled, allows remote attackers to cause a denial of service (system crash) via an SCTPChunkInit packet containing multiple invalid parameters that require a large amount of error data. (CVE-2010-1173)

fs/cifs/cifssmb.c in the CIFS implementation in the Linux kernel before 2.6.34-rc4 allows 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-2010-2248)

Buffer overflow in the ecryptfs_uid_hash macro in fs/ecryptfs/messaging.c in the eCryptfs subsystem in the Linux kernel before 2.6.35 might allow local users to gain privileges or cause a denial of service (system crash) via unspecified vectors.
