Integer overflow in the rds_rdma_pages function in net/rds/rdma.c in the Linux kernel allows local users to cause a denial of service (crash) and possibly execute arbitrary code via a crafted iovec struct in a Reliable Datagram Sockets (RDS) request, which triggers a buffer overflow.

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 openSUSE 11.3 kernel was updated to fix various bugs and security issues.

Following security issues have been fixed: CVE-2010-4347: A local user could inject ACPI code into the kernel via the world-writable 'custom_debug' file, allowing local privilege escalation.

This update of the SUSE Linux Enterprise Server 11 SP1 kernel brings the kernel to 2.6.32.24 and fixes some critical security bugs and other non-security bugs.

Following security bugs were fixed :

  - A iovec integer overflow in RDS sockets was fixed which     could lead to local attackers gaining kernel privileges.
    (CVE-2010-3865)

  - A local privilege escalation in RDS sockets allowed     local attackers to gain privileges. Please note that the     net/rds socket protocol module only lives in the.
    (CVE-2010-3904)

    -extra kernel package, which is not installed by default     on the SUSE Linux Enterprise Server 11.

  - A problem in the compat ioctl handling in video4linux     allowed local attackers with a video device plugged in     to gain privileges on x86_64 systems. (CVE-2010-2963)

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.

* Buffer overflow in eCryptfs. When /dev/ecryptfs has world-writable permissions (which it does not, by default, on Red Hat Enterprise Linux 6), a local, unprivileged user could use this flaw to cause a denial of service or possibly escalate their privileges.
(CVE-2010-2492, Important)

* Integer overflow in the RDS protocol implementation could allow a local, unprivileged user to cause a denial of service or escalate their privileges. (CVE-2010-3865, Important)

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)
