The remote Redhat Enterprise Linux 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2010:0723 advisory.

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

    This update fixes the following security issues:

    * A buffer overflow flaw was found in the ecryptfs_uid_hash() function in     the Linux kernel eCryptfs implementation. On systems that have the eCryptfs     netlink transport (Red Hat Enterprise Linux 5 does) or where the     /dev/ecryptfs file has world writable permissions (which it does not, by     default, on Red Hat Enterprise Linux 5), a local, unprivileged user could     use this flaw to cause a denial of service or possibly escalate their     privileges. (CVE-2010-2492, Important)

    * A miscalculation of the size of the free space of the initial directory     entry in a directory leaf block was found in the Linux kernel Global File     System 2 (GFS2) implementation. A local, unprivileged user with write     access to a GFS2-mounted file system could perform a rename operation on     that file system to trigger a NULL pointer dereference, possibly resulting     in a denial of service or privilege escalation. (CVE-2010-2798, Important)

    * A flaw was found in the Xen hypervisor implementation when running a     system that has an Intel CPU without Extended Page Tables (EPT) support.
    While attempting to dump information about a crashing fully-virtualized     guest, the flaw could cause the hypervisor to crash the host as well. A     user with permissions to configure a fully-virtualized guest system could     use this flaw to crash the host. (CVE-2010-2938, Moderate)

    * Information leak flaws were found in the Linux kernel's Traffic Control     Unit implementation. A local attacker could use these flaws to cause the     kernel to leak kernel memory to user-space, possibly leading to the     disclosure of sensitive information. (CVE-2010-2942, Moderate)

    * A flaw was found in the Linux kernel's XFS file system implementation.
    The file handle lookup could return an invalid inode as valid. If an XFS     file system was mounted via NFS (Network File System), a local attacker     could access stale data or overwrite existing data that reused the inodes.
    (CVE-2010-2943, Moderate)

    * An integer overflow flaw was found in the extent range checking code in     the Linux kernel's ext4 file system implementation. A local, unprivileged     user with write access to an ext4-mounted file system could trigger this     flaw by writing to a file at a very large file offset, resulting in a local     denial of service. (CVE-2010-3015, Moderate)

    * An information leak flaw was found in the Linux kernel's USB     implementation. Certain USB errors could result in an uninitialized kernel     buffer being sent to user-space. An attacker with physical access to a     target system could use this flaw to cause an information leak.
    (CVE-2010-1083, Low)

    Users should upgrade to these updated packages, which contain backported     patches to correct these issues. The system must be rebooted for this     update to take effect.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise 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.

Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leak. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2010-2492     Andre Osterhues reported an issue in the eCryptfs     subsystem. A buffer overflow condition may allow local     users to cause a denial of service or gain elevated     privileges.

  - CVE-2010-2954     Tavis Ormandy reported an issue in the irda subsystem     which may allow local users to cause a denial of service     via a NULL pointer dereference.

  - CVE-2010-3078     Dan Rosenberg discovered an issue in the XFS file system     that allows local users to read potentially sensitive     kernel memory.

  - CVE-2010-3080     Tavis Ormandy reported an issue in the ALSA sequencer     OSS emulation layer. Local users with sufficient     privileges to open /dev/sequencer (by default on Debian,     this is members of the 'audio' group) can cause a denial     of service via a NULL pointer dereference.

  - CVE-2010-3081     Ben Hawkes discovered an issue in the 32-bit     compatibility code for 64-bit systems. Local users can     gain elevated privileges due to insufficient checks in     compat_alloc_user_space allocations.

Some vulnerabilities were discovered and corrected in the Linux 2.6 kernel :

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.
(CVE-2010-2492)

The DNS resolution functionality in the CIFS implementation in the Linux kernel before 2.6.35, 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 allows 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-2010-2524)

The do_anonymous_page function in mm/memory.c in the Linux kernel before 2.6.27.52, 2.6.32.x before 2.6.32.19, 2.6.34.x before 2.6.34.4, and 2.6.35.x before 2.6.35.2 does not properly separate the stack and the heap, which allows context-dependent attackers to execute arbitrary code by writing to the bottom page of a shared memory segment, as demonstrated by a memory-exhaustion attack against the X.Org X server. (CVE-2010-2240)

Integer overflow in the ext4_ext_get_blocks function in fs/ext4/extents.c in the Linux kernel before 2.6.34 allows local users to cause a denial of service (BUG and system crash) via a write operation on the last block of a large file, followed by a sync operation. (CVE-2010-3015)

To update your kernel, please follow the directions located at :

http://www.mandriva.com/en/security/kernelupdate

Updated kernel packages that fix multiple security issues and several bugs 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 buffer overflow flaw was found in the ecryptfs_uid_hash() function in the Linux kernel eCryptfs implementation. On systems that have the eCryptfs netlink transport (Red Hat Enterprise Linux 5 does) or where the '/dev/ecryptfs' file has world-writable permissions (which it does not, by default, on Red Hat Enterprise Linux 5), a local, unprivileged user could use this flaw to cause a denial of service or possibly escalate their privileges. (CVE-2010-2492, Important)

* A miscalculation of the size of the free space of the initial directory entry in a directory leaf block was found in the Linux kernel Global File System 2 (GFS2) implementation. A local, unprivileged user with write access to a GFS2-mounted file system could perform a rename operation on that file system to trigger a NULL pointer dereference, possibly resulting in a denial of service or privilege escalation. (CVE-2010-2798, Important)

* A flaw was found in the Xen hypervisor implementation when running a system that has an Intel CPU without Extended Page Tables (EPT) support. While attempting to dump information about a crashing fully-virtualized guest, the flaw could cause the hypervisor to crash the host as well. A user with permissions to configure a fully-virtualized guest system could use this flaw to crash the host.
(CVE-2010-2938, Moderate)

* Information leak flaws were found in the Linux kernel's Traffic Control Unit implementation. A local attacker could use these flaws to cause the kernel to leak kernel memory to user-space, possibly leading to the disclosure of sensitive information. (CVE-2010-2942, Moderate)

* A flaw was found in the Linux kernel's XFS file system implementation. The file handle lookup could return an invalid inode as valid. If an XFS file system was mounted via NFS (Network File System), a local attacker could access stale data or overwrite existing data that reused the inodes. (CVE-2010-2943, Moderate)

* An integer overflow flaw was found in the extent range checking code in the Linux kernel's ext4 file system implementation. A local, unprivileged user with write access to an ext4-mounted file system could trigger this flaw by writing to a file at a very large file offset, resulting in a local denial of service. (CVE-2010-3015, Moderate)

* An information leak flaw was found in the Linux kernel's USB implementation. Certain USB errors could result in an uninitialized kernel buffer being sent to user-space. An attacker with physical access to a target system could use this flaw to cause an information leak. (CVE-2010-1083, Low)

   The Common Vulnerabilities and Exposures project (cve.mitre.org) has    assigned the names CVE-2010-1083, CVE-2010-2492, CVE-2010-2798,    CVE-2010-2938, CVE-2010-2942, CVE-2010-2943, CVE-2010-3015,    CVE-2010-3066, CVE-2010-3067, CVE-2010-3078, CVE-2010-3086,    CVE-2010-3296, CVE-2010-3432, CVE-2010-3442, CVE-2010-3477,    CVE-2010-3699, CVE-2010-3858, CVE-2010-3859, CVE-2010-3865,    CVE-2010-3876, CVE-2010-3877, CVE-2010-3880, CVE-2010-3904,    CVE-2010-4072, CVE-2010-4073, CVE-2010-4075, CVE-2010-4080,    CVE-2010-4081, CVE-2010-4083, CVE-2010-4157, CVE-2010-4158,    CVE-2010-4161, CVE-2010-4238, CVE-2010-4242, CVE-2010-4243,    CVE-2010-4247, CVE-2010-4248, CVE-2010-4249, CVE-2010-4251,    CVE-2010-4255, CVE-2010-4263, CVE-2010-4343, CVE-2010-4346,    CVE-2010-4526, CVE-2010-4655, CVE-2011-0521, CVE-2011-0710,    CVE-2011-1010, CVE-2011-1090 and CVE-2011-1478 to these issues.

b. ESX third-party update for Service Console krb5 RPMs

   This patch updates the krb5-libs and krb5-workstation RPMs of the    console OS to version 1.6.1-55.el5_6.1, which resolves multiple    security issues.

   The Common Vulnerabilities and Exposures project (cve.mitre.org) has    assigned the names CVE-2010-1323, CVE-2011-0281, and CVE-2011-0282    to these issues.

c. ESXi and ESX update to third-party component glibc

   The glibc third-party library is updated to resolve multiple    security issues.

   The Common Vulnerabilities and Exposures project (cve.mitre.org) has    assigned the names CVE-2010-0296, CVE-2011-0536, CVE-2011-1071,    CVE-2011-1095, CVE-2011-1658, and CVE-2011-1659 to these issues.

d. ESX update to third-party drivers mptsas, mpt2sas, and mptspi

   The mptsas, mpt2sas, and mptspi drivers are updated which addresses    multiple security issues in the mpt2sas driver.

   The Common Vulnerabilities and Exposures project (cve.mitre.org) has    assigned the names CVE-2011-1494 and CVE-2011-1495 to these issues.

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
