It is, therefore, affected by multiple vulnerabilities in several third-party components and libraries :

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

    (CVE-2011-1493)

  - (no CVEs assigned yet): In the rose networking stack,     when parsing the FAC_CCITT_DEST_NSAP and     FAC_CCITT_SRC_NSAP facilities fields, a remote host     could provide a length of less than 10, resulting in an     underflow in a memcpy size, causing a kernel panic due     to massive heap corruption.

Other malformed     requests could have resulted in the use of uninitialized     variables. (CVE-2011-1476)

  - Due to a failure to validate user-supplied indexes in     the driver for Yamaha YM3812 and OPL-3 chips, a     specially crafted ioctl request could have been sent to     /dev/sequencer, resulting in reading and writing beyond     the bounds of heap buffers, and potentially allowing     privilege escalation.

(CVE-2010-3880)

  - Fixed a buffer size issue in 'usb iowarrior' module,     where a malicious device could overflow a kernel buffer.
    (CVE-2010-4656)

  - The dvb_ca_ioctl function in     drivers/media/dvb/ttpci/av7110_ca.c in the Linux kernel     did not check the sign of a certain integer field, which     allowed local users to cause a denial of service (memory     corruption) or possibly have unspecified other impact     via a negative value. (CVE-2011-0521)

  - In the IrDA module, length fields provided by a peer for     names and attributes may be longer than the destination     array sizes and were not checked, this allowed local     attackers (close to the irda port) to potentially     corrupt memory. (CVE-2011-1180)

  - A system out of memory condition (denial of service)     could be triggered with a large socket backlog,     exploitable by local users. This has been addressed by     backlog limiting. (CVE-2010-4251)

  - The Radeon GPU drivers in the Linux kernel did not     properly validate data related to the AA resolve     registers, which allowed local users to write to     arbitrary memory locations associated with (1) Video RAM     (aka VRAM) or (2) the Graphics Translation Table (GTT)     via crafted values. (CVE-2011-1016)

Updated kernel packages that fix multiple security issues, several bugs, and add an enhancement 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 :

* 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 for Red Hat Bugzilla bug 484590 as provided in RHSA-2009:1243 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)
