The load_elf_binary function in fs/binfmt_elf.c in the Linux kernel before 2.6.32.8 on the x86_64 platform does not ensure that the ELF interpreter is available before a call to the SET_PERSONALITY macro, which allows local users to cause a denial of service (system crash) via a 32-bit application that attempts to execute a 64-bit application and then triggers a segmentation fault, as demonstrated by amd64_killer, related to the flush_old_exec function.

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

  - Apache Tomcat 
  - Apache Tomcat Manager
  - cURL 
  - Java Runtime Environment (JRE)
  - Kernel 
  - Microsoft SQL Express
  - OpenSSL
  - pam_krb5

From Red Hat Security Advisory 2010:0398 :

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 flaw was found in the Unidirectional Lightweight Encapsulation (ULE) implementation. A remote attacker could send a specially crafted ISO MPEG-2 Transport Stream (TS) frame to a target system, resulting in an infinite loop (denial of service). (CVE-2010-1086, Important)

* on AMD64 systems, it was discovered that the kernel did not ensure the ELF interpreter was available before making a call to the SET_PERSONALITY macro. A local attacker could use this flaw to cause a denial of service by running a 32-bit application that attempts to execute a 64-bit application. (CVE-2010-0307, Moderate)

* a flaw was found in the kernel connector implementation. A local, unprivileged user could trigger this flaw by sending an arbitrary number of notification requests using specially crafted netlink messages, resulting in a denial of service. (CVE-2010-0410, Moderate)

* a flaw was found in the Memory-mapped I/O (MMIO) instruction decoder in the Xen hypervisor implementation. An unprivileged guest user could use this flaw to trick the hypervisor into emulating a certain instruction, which could crash the guest (denial of service).
(CVE-2010-0730, Moderate)

* a divide-by-zero flaw was found in the azx_position_ok() function in the driver for Intel High Definition Audio, snd-hda-intel. A local, unprivileged user could trigger this flaw to cause a kernel crash (denial of service). (CVE-2010-1085, Moderate)

This update also fixes the following bugs :

* in some cases, booting a system with the 'iommu=on' kernel parameter resulted in a Xen hypervisor panic. (BZ#580199)

* the fnic driver flushed the Rx queue instead of the Tx queue after fabric login. This caused crashes in some cases. (BZ#580829)

* 'kernel unaligned access' warnings were logged to the dmesg log on some systems. (BZ#580832)

* the 'Northbridge Error, node 1, core: -1 K8 ECC error' error occurred on some systems using the amd64_edac driver. (BZ#580836)

* in rare circumstances, when using kdump and booting a kernel with 'crashkernel=128M@16M', the kdump kernel did not boot after a crash.
(BZ#580838)

* TLB page table entry flushing was done incorrectly on IBM System z, possibly causing crashes, subtle data inconsistency, or other issues.
(BZ#580839)

* iSCSI failover times were slower than in Red Hat Enterprise Linux 5.3. (BZ#580840)

* fixed floating point state corruption after signal. (BZ#580841)

* in certain circumstances, under heavy load, certain network interface cards using the bnx2 driver and configured to use MSI-X, could stop processing interrupts and then network connectivity would cease. (BZ#587799)

* cnic parts resets could cause a deadlock when the bnx2 device was enslaved in a bonding device and that device had an associated VLAN.
(BZ#581148)

* some BIOS implementations initialized interrupt remapping hardware in a way the Xen hypervisor implementation did not expect. This could have caused a system hang during boot. (BZ#581150)

* AMD Magny-Cours systems panicked when booting a 32-bit kernel.
(BZ#580846)

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.

From Red Hat Security Advisory 2010:0146 :

Updated kernel packages that fix multiple security issues and several bugs are now available for Red Hat Enterprise Linux 4.

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 NULL pointer dereference flaw was found in the sctp_rcv_ootb() function in the Linux kernel Stream Control Transmission Protocol (SCTP) implementation. A remote attacker could send a specially crafted SCTP packet to a target system, resulting in a denial of service. (CVE-2010-0008, Important)

* a NULL pointer dereference flaw was found in the Linux kernel.
During a core dump, the kernel did not check if the Virtual Dynamically-linked Shared Object page was accessible. On Intel 64 and AMD64 systems, a local, unprivileged user could use this flaw to cause a kernel panic by running a crafted 32-bit application.
(CVE-2009-4271, Important)

* an information leak was found in the print_fatal_signal() implementation in the Linux kernel. When '/proc/sys/kernel/print-fatal-signals' is set to 1 (the default value is 0), memory that is reachable by the kernel could be leaked to user-space. This issue could also result in a system crash. Note that this flaw only affected the i386 architecture. (CVE-2010-0003, Moderate)

* on AMD64 systems, it was discovered that the kernel did not ensure the ELF interpreter was available before making a call to the SET_PERSONALITY macro. A local attacker could use this flaw to cause a denial of service by running a 32-bit application that attempts to execute a 64-bit application. (CVE-2010-0307, Moderate)

* missing capability checks were found in the ebtables implementation, used for creating an Ethernet bridge firewall. This could allow a local, unprivileged user to bypass intended capability restrictions and modify ebtables rules. (CVE-2010-0007, Low)

This update also fixes the following bugs :

* under some circumstances, a locking bug could have caused an online ext3 file system resize to deadlock, which may have, in turn, caused the file system or the entire system to become unresponsive. In either case, a reboot was required after the deadlock. With this update, using resize2fs to perform an online resize of an ext3 file system works as expected. (BZ#553135)

* some ATA and SCSI devices were not honoring the barrier=1 mount option, which could result in data loss after a crash or power loss.
This update applies a patch to the Linux SCSI driver to ensure ordered write caching. This solution does not provide cache flushes; however, it does provide data integrity on devices that have no write caching (or where write caching is disabled) and no command queuing. For systems that have command queuing or write cache enabled there is no guarantee of data integrity after a crash. (BZ#560563)

* it was found that lpfc_find_target() could loop continuously when scanning a list of nodes due to a missing spinlock. This missing spinlock allowed the list to be changed after the list_empty() test, resulting in a NULL value, causing the loop. This update adds the spinlock, resolving the issue. (BZ#561453)

* the fix for CVE-2009-4538 provided by RHSA-2010:0020 introduced a regression, preventing Wake on LAN (WoL) working for network devices using the Intel PRO/1000 Linux driver, e1000e. Attempting to configure WoL for such devices resulted in the following error, even when configuring valid options :

'Cannot set new wake-on-lan settings: Operation not supported not setting wol'

This update resolves this regression, and WoL now works as expected for network devices using the e1000e driver. (BZ#565496)

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.

This update provides a fix to the correction of CVE-2010-0307, which resulted in crashes when running i586 applications on x86_64.

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

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

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

The gfs2_lock function in the Linux kernel before 2.6.34-rc1-next-20100312, and the gfs_lock function in the Linux kernel on Red Hat Enterprise Linux (RHEL) 5 and 6, does not properly remove POSIX locks on files that are setgid without group-execute permission, which allows local users to cause a denial of service (BUG and system crash) by locking a file on a (1) GFS or (2) GFS2 filesystem, and then changing this file's permissions. (CVE-2010-0727)

The do_pages_move function in mm/migrate.c in the Linux kernel before 2.6.33-rc7 does not validate node values, which allows local users to read arbitrary kernel memory locations, cause a denial of service (OOPS), and possibly have unspecified other impact by specifying a node that is not part of the kernel's node set. (CVE-2010-0415)

drivers/net/e1000e/netdev.c in the e1000e driver in the Linux kernel 2.6.32.3 and earlier does not properly check the size of an Ethernet frame that exceeds the MTU, which allows remote attackers to have an unspecified impact via crafted packets, a related issue to CVE-2009-4537. (CVE-2009-4538)

The load_elf_binary function in fs/binfmt_elf.c in the Linux kernel before 2.6.32.8 on the x86_64 platform does not ensure that the ELF interpreter is available before a call to the SET_PERSONALITY macro, which allows local users to cause a denial of service (system crash) via a 32-bit application that attempts to execute a 64-bit application and then triggers a segmentation fault, as demonstrated by amd64_killer, related to the flush_old_exec function. (CVE-2010-0307)

Aditionally, it was added support for some backlight models used in Samsung laptops and fixes to detect Saitek X52 joysticks.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

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 flaw was found in the Unidirectional Lightweight Encapsulation (ULE) implementation. A remote attacker could send a specially crafted ISO MPEG-2 Transport Stream (TS) frame to a target system, resulting in an infinite loop (denial of service). (CVE-2010-1086, Important)

* on AMD64 systems, it was discovered that the kernel did not ensure the ELF interpreter was available before making a call to the SET_PERSONALITY macro. A local attacker could use this flaw to cause a denial of service by running a 32-bit application that attempts to execute a 64-bit application. (CVE-2010-0307, Moderate)

* a flaw was found in the kernel connector implementation. A local, unprivileged user could trigger this flaw by sending an arbitrary number of notification requests using specially crafted netlink messages, resulting in a denial of service. (CVE-2010-0410, Moderate)

* a flaw was found in the Memory-mapped I/O (MMIO) instruction decoder in the Xen hypervisor implementation. An unprivileged guest user could use this flaw to trick the hypervisor into emulating a certain instruction, which could crash the guest (denial of service).
(CVE-2010-0730, Moderate)

* a divide-by-zero flaw was found in the azx_position_ok() function in the driver for Intel High Definition Audio, snd-hda-intel. A local, unprivileged user could trigger this flaw to cause a kernel crash (denial of service). (CVE-2010-1085, Moderate)

This update also fixes the following bugs :

* in some cases, booting a system with the 'iommu=on' kernel parameter resulted in a Xen hypervisor panic. (BZ#580199)

* the fnic driver flushed the Rx queue instead of the Tx queue after fabric login. This caused crashes in some cases. (BZ#580829)

* 'kernel unaligned access' warnings were logged to the dmesg log on some systems. (BZ#580832)

* the 'Northbridge Error, node 1, core: -1 K8 ECC error' error occurred on some systems using the amd64_edac driver. (BZ#580836)

* in rare circumstances, when using kdump and booting a kernel with 'crashkernel=128M@16M', the kdump kernel did not boot after a crash.
(BZ#580838)

* TLB page table entry flushing was done incorrectly on IBM System z, possibly causing crashes, subtle data inconsistency, or other issues.
(BZ#580839)

* iSCSI failover times were slower than in Red Hat Enterprise Linux 5.3. (BZ#580840)

* fixed floating point state corruption after signal. (BZ#580841)

* in certain circumstances, under heavy load, certain network interface cards using the bnx2 driver and configured to use MSI-X, could stop processing interrupts and then network connectivity would cease. (BZ#587799)

* cnic parts resets could cause a deadlock when the bnx2 device was enslaved in a bonding device and that device had an associated VLAN.
(BZ#581148)

* some BIOS implementations initialized interrupt remapping hardware in a way the Xen hypervisor implementation did not expect. This could have caused a system hang during boot. (BZ#581150)

* AMD Magny-Cours systems panicked when booting a 32-bit kernel.
(BZ#580846)

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.

Updated kernel packages that fix multiple security issues and several bugs are now available for Red Hat Enterprise Linux 4.

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 NULL pointer dereference flaw was found in the sctp_rcv_ootb() function in the Linux kernel Stream Control Transmission Protocol (SCTP) implementation. A remote attacker could send a specially crafted SCTP packet to a target system, resulting in a denial of service. (CVE-2010-0008, Important)

* a NULL pointer dereference flaw was found in the Linux kernel.
During a core dump, the kernel did not check if the Virtual Dynamically-linked Shared Object page was accessible. On Intel 64 and AMD64 systems, a local, unprivileged user could use this flaw to cause a kernel panic by running a crafted 32-bit application.
(CVE-2009-4271, Important)

* an information leak was found in the print_fatal_signal() implementation in the Linux kernel. When '/proc/sys/kernel/print-fatal-signals' is set to 1 (the default value is 0), memory that is reachable by the kernel could be leaked to user-space. This issue could also result in a system crash. Note that this flaw only affected the i386 architecture. (CVE-2010-0003, Moderate)

* on AMD64 systems, it was discovered that the kernel did not ensure the ELF interpreter was available before making a call to the SET_PERSONALITY macro. A local attacker could use this flaw to cause a denial of service by running a 32-bit application that attempts to execute a 64-bit application. (CVE-2010-0307, Moderate)

* missing capability checks were found in the ebtables implementation, used for creating an Ethernet bridge firewall. This could allow a local, unprivileged user to bypass intended capability restrictions and modify ebtables rules. (CVE-2010-0007, Low)

This update also fixes the following bugs :

* under some circumstances, a locking bug could have caused an online ext3 file system resize to deadlock, which may have, in turn, caused the file system or the entire system to become unresponsive. In either case, a reboot was required after the deadlock. With this update, using resize2fs to perform an online resize of an ext3 file system works as expected. (BZ#553135)

* some ATA and SCSI devices were not honoring the barrier=1 mount option, which could result in data loss after a crash or power loss.
This update applies a patch to the Linux SCSI driver to ensure ordered write caching. This solution does not provide cache flushes; however, it does provide data integrity on devices that have no write caching (or where write caching is disabled) and no command queuing. For systems that have command queuing or write cache enabled there is no guarantee of data integrity after a crash. (BZ#560563)

* it was found that lpfc_find_target() could loop continuously when scanning a list of nodes due to a missing spinlock. This missing spinlock allowed the list to be changed after the list_empty() test, resulting in a NULL value, causing the loop. This update adds the spinlock, resolving the issue. (BZ#561453)

* the fix for CVE-2009-4538 provided by RHSA-2010:0020 introduced a regression, preventing Wake on LAN (WoL) working for network devices using the Intel PRO/1000 Linux driver, e1000e. Attempting to configure WoL for such devices resulted in the following error, even when configuring valid options :

'Cannot set new wake-on-lan settings: Operation not supported not setting wol'

This update resolves this regression, and WoL now works as expected for network devices using the e1000e driver. (BZ#565496)

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.

Mathias Krause discovered that the Linux kernel did not correctly handle missing ELF interpreters. A local attacker could exploit this to cause the system to crash, leading to a denial of service.
(CVE-2010-0307)

Marcelo Tosatti discovered that the Linux kernel's hardware virtualization did not correctly handle reading the /dev/port special device. A local attacker in a guest operating system could issue a specific read that would cause the host system to crash, leading to a denial of service. (CVE-2010-0309)

Sebastian Krahmer discovered that the Linux kernel did not correctly handle netlink connector messages. A local attacker could exploit this to consume kernel memory, leading to a denial of service.
(CVE-2010-0410)

Ramon de Carvalho Valle discovered that the Linux kernel did not correctly validate certain memory migration calls. A local attacker could exploit this to read arbitrary kernel memory or cause a system crash, leading to a denial of service. (CVE-2010-0415)

Jermome Marchand and Mikael Pettersson discovered that the Linux kernel did not correctly handle certain futex operations. A local attacker could exploit this to cause a system crash, leading to a denial of service. (CVE-2010-0622, CVE-2010-0623).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

CVE-2009-4020: Stack-based buffer overflow in the hfs subsystem in the Linux kernel 2.6.32 allows remote attackers to have an unspecified impact via a crafted Hierarchical File System (HFS) filesystem, related to the hfs_readdir function in fs/hfs/dir.c.

CVE-2010-0307: The load_elf_binary function in fs/binfmt_elf.c in the Linux kernel before 2.6.32.8 on the x86_64 platform does not ensure that the ELF interpreter is available before a call to the SET_PERSONALITY macro, which allows local users to cause a denial of service (system crash) via a 32-bit application that attempts to execute a 64-bit application and then triggers a segmentation fault, as demonstrated by amd64_killer, related to the flush_old_exec function.

CVE-2010-0622: The wake_futex_pi function in kernel/futex.c in the Linux kernel before 2.6.33-rc7 does not properly handle certain unlock operations for a Priority Inheritance (PI) futex, which allows local users to cause a denial of service (OOPS) and possibly have unspecified other impact via vectors involving modification of the futex value from user space.

CVE-2010-0410: drivers/connector/connector.c in the Linux kernel before 2.6.32.8 allows local users to cause a denial of service (memory consumption and system crash) by sending the kernel many NETLINK_CONNECTOR messages.

CVE-2010-0415: The do_pages_move function in mm/migrate.c in the Linux kernel before 2.6.33-rc7 does not validate node values, which allows local users to read arbitrary kernel memory locations, cause a denial of service (OOPS), and possibly have unspecified other impact by specifying a node that is not part of the kernel's node set.

(CVE-2010-0307)

  - Users could send/allocate arbitrary amounts of     NETLINK_CONNECTOR messages to the kernel, causing OOM     condition, killing selected processes or halting the     system. (CVE-2010-0410)

  - The do_pages_move function in mm/migrate.c in the Linux     kernel before 2.6.33-rc7 does not validate node values,     which allows local users to read arbitrary kernel memory     locations, cause a denial of service (OOPS), and     possibly have unspecified other impact by specifying a     node that is not part of the kernels node set.
    (CVE-2010-0415)

  - net/bridge/netfilter/ebtables.c in the ebtables module     in the netfilter framework in the Linux kernel before     2.6.33-rc4 does not require the CAP_NET_ADMIN capability     for setting or modifying rules, which allows local users     to bypass intended access restrictions and configure     arbitrary network-traffic filtering via a modified     ebtables application. (CVE-2010-0007)

  - drivers/net/e1000/e1000_main.c in the e1000 driver in     the Linux kernel 2.6.32.3 and earlier handles Ethernet     frames that exceed the MTU by processing certain     trailing payload data as if it were a complete frame,     which allows remote attackers to bypass packet filters     via a large packet with a crafted payload.
    (CVE-2009-4536)

  - drivers/net/e1000e/netdev.c in the e1000e driver in the     Linux kernel 2.6.32.3 and earlier does not properly     check the size of an Ethernet frame that exceeds the     MTU, which allows remote attackers to have an     unspecified impact via crafted packets. (CVE-2009-4538)

  - The print_fatal_signal function in kernel/signal.c in     the Linux kernel before 2.6.32.4 on the i386 platform,     when print-fatal-signals is enabled, allows local users     to discover the contents of arbitrary memory locations     by jumping to an address and then reading a log file,     and might allow local users to cause a denial of service     (system slowdown or crash) by jumping to an address.
    (CVE-2010-0003)

  - The poll_mode_io file for the megaraid_sas driver in the     Linux kernel 2.6.31.6 and earlier has world-writable     permissions, which allows local users to change the I/O     mode of the driver by modifying this file.
