This update fixes the following security issues :

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

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

  - A heap overflow flaw in the Linux kernel's Transparent     Inter-Process Communication protocol (TIPC)     implementation could allow a local, unprivileged user to     escalate their privileges. (CVE-2010-3859, Important)

  - An integer overflow flaw was found in the Linux kernel's     Reliable Datagram Sockets (RDS) protocol implementation.
    A local, unprivileged user could use this flaw to cause     a denial of service or escalate their privileges.
    (CVE-2010-3865, Important)

  - A flaw was found in the Xenbus code for the unified     block-device I/O interface back end. A privileged guest     user could use this flaw to cause a denial of service on     the host system running the Xen hypervisor.
    (CVE-2010-3699, Moderate)

  - Missing sanity checks were found in setup_arg_pages() in     the Linux kernel. When making the size of the argument     and environment area on the stack very large, it could     trigger a BUG_ON(), resulting in a local denial of     service. (CVE-2010-3858, Moderate)

  - A flaw was found in inet_csk_diag_dump() in the Linux     kernel's module for monitoring the sockets of INET     transport protocols. By sending a netlink message with     certain bytecode, a local, unprivileged user could cause     a denial of service. (CVE-2010-3880, Moderate)

  - Missing sanity checks were found in gdth_ioctl_alloc()     in the gdth driver in the Linux kernel. A local user     with access to '/dev/gdth' on a 64-bit system could use     this flaw to cause a denial of service or escalate their     privileges. (CVE-2010-4157, Moderate)

  - The fix put into kernel-2.6.18-164.el5 introduced a     regression. A local, unprivileged user could use this     flaw to cause a denial of service. (CVE-2010-4161,     Moderate)

  - A NULL pointer dereference flaw was found in the     Bluetooth HCI UART driver in the Linux kernel. A local,     unprivileged user could use this flaw to cause a denial     of service. (CVE-2010-4242, Moderate)

  - It was found that a malicious guest running on the Xen     hypervisor could place invalid data in the memory that     the guest shared with the blkback and blktap back-end     drivers, resulting in a denial of service on the host     system. (CVE-2010-4247, Moderate)

  - A flaw was found in the Linux kernel's CPU time clocks     implementation for the POSIX clock interface. A local,     unprivileged user could use this flaw to cause a denial     of service. (CVE-2010-4248, Moderate)

  - Missing initialization flaws in the Linux kernel could     lead to information leaks. (CVE-2010-3876,     CVE-2010-4083, Low)

The remote VMware ESX / ESXi host is missing a security-related patch.
It is, therefore, affected by multiple vulnerabilities in several third-party components and libraries :

  - Kernel
  - krb5
  - glibc
  - mtp2sas
  - mptsas
  - mptspi

The remote CentOS system is missing a security update which has been documented in Red Hat advisory RHSA-2011-0004.
