Integer underflow in the ieee80211_rx function in net/ieee80211/ieee80211_rx.c in the Linux kernel 2.6.x before 2.6.23 allows remote attackers to cause a denial of service (crash) via a crafted SKB length value in a runt IEEE 802.11 frame when the IEEE80211_STYPE_QOS_DATA flag is set, aka an "off-by-two error."

From Red Hat Security Advisory 2007:1104 :

Updated kernel packages that fix various security issues and several bugs in the Red Hat Enterprise Linux 4 kernel are now available.

This update has been rated as having important security impact by the Red Hat Security Response Team.

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

These updated packages fix the following security issues :

A flaw was found in the handling of IEEE 802.11 frames, which affected several wireless LAN modules. In certain situations, a remote attacker could trigger this flaw by sending a malicious packet over a wireless network, causing a denial of service (kernel crash). (CVE-2007-4997, Important)

A memory leak was found in the Red Hat Content Accelerator kernel patch. A local user could use this flaw to cause a denial of service (memory exhaustion). (CVE-2007-5494, Important)

Additionally, the following bugs were fixed :

* when running the 'ls -la' command on an NFSv4 mount point, incorrect file attributes, and outdated file size and timestamp information were returned. As well, symbolic links may have been displayed as actual files.

* a bug which caused the cmirror write path to appear deadlocked after a successful recovery, which may have caused syncing to hang, has been resolved.

* a kernel panic which occurred when manually configuring LCS interfaces on the IBM S/390 has been resolved.

* when running a 32-bit binary on a 64-bit system, it was possible to mmap page at address 0 without flag MAP_FIXED set. This has been resolved in these updated packages.

* the Non-Maskable Interrupt (NMI) Watchdog did not increment the NMI interrupt counter in '/proc/interrupts' on systems running an AMD Opteron CPU. This caused systems running NMI Watchdog to restart at regular intervals.

* a bug which caused the diskdump utility to run very slowly on devices using Fusion MPT has been resolved.

All users are advised to upgrade to these updated packages, which resolve these issues.

The remote Oracle Linux 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2007-0993 advisory.

  - a bug which caused the diskdump utility to run very     slowly on devices using Fusion MPT has been resolved.

These new kernel packages contain fixes for the following security issues :

A memory leak was found in the Red Hat Content Accelerator kernel patch. A local user could use this flaw to cause a denial of service (memory exhaustion). (CVE-2007-5494, Important)

A flaw was found in the handling of IEEE 802.11 frames affecting several wireless LAN modules. In certain circumstances, a remote attacker could trigger this flaw by sending a malicious packet over a wireless network and cause a denial of service (kernel crash).
(CVE-2007-4997, Important).

A flaw was found in the Advanced Linux Sound Architecture (ALSA). A local user who had the ability to read the /proc/driver/snd-page-alloc file could see portions of kernel memory. (CVE-2007-4571, Moderate).

In addition to the security issues described above, several bug fixes preventing possible memory corruption, system crashes, SCSI I/O fails, networking drivers performance regression and journaling block device layer issue were also included.

This kernel update fixes the following security problems :

  - The sysfs_readdir function in the Linux kernel 2.6     allows local users to cause a denial of service (kernel     OOPS) by dereferencing a NULL pointer to an inode in a     dentry. (CVE-2007-3104)

  - A 2 byte buffer underflow in the ieee80211 stack was     fixed, which might be used by attackers in the local     WLAN reach to crash the machine. (CVE-2007-4997)

  - The CIFS filesystem, when Unix extension support is     enabled, did not honor the umask of a process, which     allowed local users to gain privileges. (CVE-2007-3740)

  - It was possible for local user to become root by     exploiting a bug in the IA32 system call emulation. This     problem affects the x86_64 platform only, on all     distributions. (CVE-2007-4573)

    This problem was fixed for regular kernels, but had not     been fixed for the XEN kernels. This update fixes the     problem also for the XEN kernels.

  - The (1) aac_cfg_open and (2) aac_compat_ioctl functions     in the SCSI layer ioctl path in aacraid did not check     permissions for ioctls, which might have allowed local     users to cause a denial of service or gain privileges.
    (CVE-2007-4308)

  - The Linux kernel checked the wrong global variable for     the CIFS sec mount option, which might allow remote     attackers to spoof CIFS network traffic that the client     configured for security signatures, as demonstrated by     lack of signing despite sec=ntlmv2i in a SetupAndX     request. (CVE-2007-3843)

  - Multiple buffer overflows in CIFS VFS in the Linux     kernel allowed remote attackers to cause a denial of     service (crash) and possibly execute arbitrary code via     long SMB responses that trigger the overflows in the     SendReceive function. (CVE-2007-5904)

    This requires the attacker to mis-present / replace a     CIFS server the client machine is connected to.

  - Buffer overflow in the isdn_net_setcfg function in     isdn_net.c in the Linux kernel allowed local users to     have an unknown impact via a crafted argument to the     isdn_ioctl function. (CVE-2007-6063)

The CIFS filesystem in the Linux kernel before 2.6.22, when Unix extension support is enabled, does not honor the umask of a process, which allows local users to gain privileges. (CVE-2007-3740)

The drm/i915 component in the Linux kernel before 2.6.22.2, when used with i965G and later chipsets, allows local users with access to an X11 session and Direct Rendering Manager (DRM) to write to arbitrary memory locations and gain privileges via a crafted batchbuffer.
(CVE-2007-3851)

The (1) hugetlb_vmtruncate_list and (2) hugetlb_vmtruncate functions in fs/hugetlbfs/inode.c in the Linux kernel before 2.6.19-rc4 perform certain prio_tree calculations using HPAGE_SIZE instead of PAGE_SIZE units, which allows local users to cause a denial of service (panic) via unspecified vectors. (CVE-2007-4133)

The IA32 system call emulation functionality in Linux kernel 2.4.x and 2.6.x before 2.6.22.7, when running on the x86_64 architecture, does not zero extend the eax register after the 32bit entry path to ptrace is used, which might allow local users to gain privileges by triggering an out-of-bounds access to the system call table using the %RAX register. This vulnerability is now being fixed in the Xen kernel too. (CVE-2007-4573)

Integer underflow in the ieee80211_rx function in net/ieee80211/ieee80211_rx.c in the Linux kernel 2.6.x before 2.6.23 allows remote attackers to cause a denial of service (crash) via a crafted SKB length value in a runt IEEE 802.11 frame when the IEEE80211_STYPE_QOS_DATA flag is set, aka an off-by-two error.
(CVE-2007-4997)

The disconnect method in the Philips USB Webcam (pwc) driver in Linux kernel 2.6.x before 2.6.22.6 relies on user space to close the device, which allows user-assisted local attackers to cause a denial of service (USB subsystem hang and CPU consumption in khubd) by not closing the device after the disconnect is invoked. NOTE: this rarely crosses privilege boundaries, unless the attacker can convince the victim to unplug the affected device. (CVE-2007-5093)

A race condition in the directory notification subsystem (dnotify) in Linux kernel 2.6.x before 2.6.24.6, and 2.6.25 before 2.6.25.1, allows local users to cause a denial of service (OOPS) and possibly gain privileges via unspecified vectors. (CVE-2008-1375)

The Linux kernel before 2.6.25.2 does not apply a certain protection mechanism for fcntl functionality, which allows local users to (1) execute code in parallel or (2) exploit a race condition to obtain re-ordered access to the descriptor table. (CVE-2008-1669)

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

The minix filesystem code allows local users to cause a denial of service (hang) via a malformed minix file stream (CVE-2006-6058).

An integer underflow in the Linux kernel prior to 2.6.23 allows remote attackers to cause a denial of service (crash) via a crafted SKB length value in a runt IEEE 802.11 frame when the IEEE80211_STYPE_QOS_DATA flag is set (CVE-2007-4997).

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

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

The minix filesystem did not properly validate certain filesystem values. If a local attacker could trick the system into attempting to mount a corrupted minix filesystem, the kernel could be made to hang for long periods of time, resulting in a denial of service.
(CVE-2006-6058)

Alexander Schulze discovered that the skge driver does not properly use the spin_lock and spin_unlock functions. Remote attackers could exploit this by sending a flood of network traffic and cause a denial of service (crash). (CVE-2006-7229)

Hugh Dickins discovered that hugetlbfs performed certain prio_tree calculations using HPAGE_SIZE instead of PAGE_SIZE. A local user could exploit this and cause a denial of service via kernel panic.
(CVE-2007-4133)

Chris Evans discovered an issue with certain drivers that use the ieee80211_rx function. Remote attackers could send a crafted 802.11 frame and cause a denial of service via crash. (CVE-2007-4997)

Hugh Dickins discovered the when using the tmpfs filesystem, under rare circumstances, a kernel page may be improperly cleared. A local user may be able to exploit this and read sensitive kernel data or cause a denial of service via crash. (CVE-2007-6417)

Bill Roman discovered that the VFS subsystem did not properly check access modes. A local user may be able to gain removal privileges on directories. (CVE-2008-0001).

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.

The minix filesystem did not properly validate certain filesystem values. If a local attacker could trick the system into attempting to mount a corrupted minix filesystem, the kernel could be made to hang for long periods of time, resulting in a denial of service. This was only vulnerable in Ubuntu 7.04 and 7.10. (CVE-2006-6058)

The signal handling on PowerPC systems using HTX allowed local users to cause a denial of service via floating point corruption. This was only vulnerable in Ubuntu 6.10 and 7.04. (CVE-2007-3107)

The Linux kernel did not properly validate the hop-by-hop IPv6 extended header. Remote attackers could send a crafted IPv6 packet and cause a denial of service via kernel panic. This was only vulnerable in Ubuntu 7.04. (CVE-2007-4567)

The JFFS2 filesystem with ACL support enabled did not properly store permissions during inode creation and ACL setting. Local users could possibly access restricted files after a remount. This was only vulnerable in Ubuntu 7.04 and 7.10. (CVE-2007-4849)

Chris Evans discovered an issue with certain drivers that use the ieee80211_rx function. Remote attackers could send a crafted 802.11 frame and cause a denial of service via crash. This was only vulnerable in Ubuntu 7.04 and 7.10. (CVE-2007-4997)

Alex Smith discovered an issue with the pwc driver for certain webcam devices. A local user with physical access to the system could remove the device while a userspace application had it open and cause the USB subsystem to block. This was only vulnerable in Ubuntu 7.04.
(CVE-2007-5093)

This was only vulnerable in Ubuntu 7.04 and 7.10. (CVE-2007-5500)

It was discovered that the Linux kernel could dereference a NULL pointer when processing certain IPv4 TCP packets. A remote attacker could send a crafted TCP ACK response and cause a denial of service via crash. This was only vulnerable in Ubuntu 7.10. (CVE-2007-5501)

Warren Togami discovered that the hrtimer subsystem did not properly check for large relative timeouts. A local user could exploit this and cause a denial of service via soft lockup. (CVE-2007-5966)

Venustech AD-LAB discovered a buffer overflow in the isdn net subsystem. This issue is exploitable by local users via crafted input to the isdn_ioctl function. (CVE-2007-6063)

It was discovered that the isdn subsystem did not properly check for NULL termination when performing ioctl handling. A local user could exploit this to cause a denial of service. (CVE-2007-6151)

Hugh Dickins discovered the when using the tmpfs filesystem, under rare circumstances, a kernel page may be improperly cleared. A local user may be able to exploit this and read sensitive kernel data or cause a denial of service via crash. (CVE-2007-6417)

Bill Roman discovered that the VFS subsystem did not properly check access modes. A local user may be able to gain removal privileges on directories. (CVE-2008-0001).

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.

This kernel update fixes the following security problems :

CVE-2008-0007: Insufficient range checks in certain fault handlers could be used by local attackers to potentially read or write kernel memory.

CVE-2008-0001: Incorrect access mode checks could be used by local attackers to corrupt directory contents and so cause denial of service attacks or potentially execute code.

CVE-2007-5966: Integer overflow in the hrtimer_start function in kernel/hrtimer.c in the Linux kernel before 2.6.23.10 allows local users to execute arbitrary code or cause a denial of service (panic) via a large relative timeout value. NOTE: some of these details are obtained from third-party information.

CVE-2007-3843: The Linux kernel checked the wrong global variable for the CIFS sec mount option, which might allow remote attackers to spoof CIFS network traffic that the client configured for security signatures, as demonstrated by lack of signing despite sec=ntlmv2i in a SetupAndX request.

CVE-2007-2242: The IPv6 protocol allows remote attackers to cause a denial of service via crafted IPv6 type 0 route headers (IPV6_RTHDR_TYPE_0) that create network amplification between two routers.

CVE-2007-6417: The shmem_getpage function (mm/shmem.c) in Linux kernel 2.6.11 through 2.6.23 does not properly clear allocated memory in some rare circumstances, which might allow local users to read sensitive kernel data or cause a denial of service (crash).

CVE-2007-4308: The (1) aac_cfg_open and (2) aac_compat_ioctl functions in the SCSI layer ioctl path in aacraid in the Linux kernel did not check permissions for ioctls, which might have allowed local users to cause a denial of service or gain privileges.

CVE-2007-3740: The CIFS filesystem, when Unix extension support is enabled, does not honor the umask of a process, which allows local users to gain privileges.

CVE-2007-3848: The Linux kernel allowed local users to send arbitrary signals to a child process that is running at higher privileges by causing a setuid-root parent process to die, which delivers an attacker-controlled parent process death signal (PR_SET_PDEATHSIG).

CVE-2007-4997: Integer underflow in the ieee80211_rx function in net/ieee80211/ieee80211_rx.c in the Linux kernel allowed remote attackers to cause a denial of service (crash) via a crafted SKB length value in a runt IEEE 802.11 frame when the IEEE80211_STYPE_QOS_DATA flag is set, aka an 'off-by-two error.'

CVE-2007-6063: Buffer overflow in the isdn_net_setcfg function in isdn_net.c in the Linux kernel allowed local users to have an unknown impact via a crafted argument to the isdn_ioctl function.

This kernel update fixes the following security problems :

++ CVE-2007-3104: The sysfs_readdir function in the Linux kernel 2.6 allows local users to cause a denial of service (kernel OOPS) by dereferencing a NULL pointer to an inode in a dentry.

++ CVE-2007-4997: A 2 byte buffer underflow in the ieee80211 stack was fixed, which might be used by attackers in the local WLAN reach to crash the machine.

++ CVE-2007-3740: The CIFS filesystem, when Unix extension support is enabled, did not honor the umask of a process, which allowed local users to gain privileges.

++ CVE-2007-4573: It was possible for local user to become root by exploiting a bug in the IA32 system call emulation. This problem affects the x86_64 platform only, on all distributions.

This problem was fixed for regular kernels, but had not been fixed for the XEN kernels. This update fixes the problem also for the XEN kernels.

++ CVE-2007-4308: The (1) aac_cfg_open and (2) aac_compat_ioctl functions in the SCSI layer ioctl path in aacraid did not check permissions for ioctls, which might have allowed local users to cause a denial of service or gain privileges.

++ CVE-2007-3843: The Linux kernel checked the wrong global variable for the CIFS sec mount option, which might allow remote attackers to spoof CIFS network traffic that the client configured for security signatures, as demonstrated by lack of signing despite sec=ntlmv2i in a SetupAndX request.

++ CVE-2007-5904: Multiple buffer overflows in CIFS VFS in the Linux kernel allowed remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via long SMB responses that trigger the overflows in the SendReceive function.

This requires the attacker to mis-present / replace a CIFS server the client machine is connected to.

++ CVE-2007-6063: Buffer overflow in the isdn_net_setcfg function in isdn_net.c in the Linux kernel allowed local users to have an unknown impact via a crafted argument to the isdn_ioctl function.

Furthermore, this kernel catches up to the SLE 10 state of the kernel, with numerous additional fixes.

The remote Redhat Enterprise Linux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2007:1104 advisory.

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

    These updated packages fix the following security issues:

    A flaw was found in the handling of IEEE 802.11 frames, which affected     several wireless LAN modules. In certain situations, a remote attacker     could trigger this flaw by sending a malicious packet over a wireless     network, causing a denial of service (kernel crash).
    (CVE-2007-4997, Important)

    A memory leak was found in the Red Hat Content Accelerator kernel patch.
    A local user could use this flaw to cause a denial of service (memory     exhaustion). (CVE-2007-5494, Important)

    Additionally, the following bugs were fixed:

    * when running the ls -la command on an NFSv4 mount point, incorrect     file attributes, and outdated file size and timestamp information were     returned. As well, symbolic links may have been displayed as actual files.

    * a bug which caused the cmirror write path to appear deadlocked after a     successful recovery, which may have caused syncing to hang, has been     resolved.

    * a kernel panic which occurred when manually configuring LCS interfaces on     the IBM S/390 has been resolved.

    * when running a 32-bit binary on a 64-bit system, it was possible to     mmap page at address 0 without flag MAP_FIXED set. This has been     resolved in these updated packages.

    * the Non-Maskable Interrupt (NMI) Watchdog did not increment the NMI     interrupt counter in /proc/interrupts on systems running an AMD Opteron     CPU. This caused systems running NMI Watchdog to restart at regular     intervals.

    * a bug which caused the diskdump utility to run very slowly on devices     using Fusion MPT has been resolved.

    All users are advised to upgrade to these updated packages, which resolve     these issues.

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.

Updated kernel packages that fix various security issues and several bugs in the Red Hat Enterprise Linux 4 kernel are now available.

This update has been rated as having important security impact by the Red Hat Security Response Team.

* when running a 32-bit binary on a 64-bit system, it was possible to mmap page at address 0 without flag MAP_FIXED set. This has been resolved in these updated packages.

* the Non-Maskable Interrupt (NMI) Watchdog did not increment the NMI interrupt counter in '/proc/interrupts' on systems running an AMD Opteron CPU. This caused systems running NMI Watchdog to restart at regular intervals.

* a bug which caused the diskdump utility to run very slowly on devices using Fusion MPT has been resolved.

All users are advised to upgrade to these updated packages, which resolve these issues.

The minix filesystem did not properly validate certain filesystem values. If a local attacker could trick the system into attempting to mount a corrupted minix filesystem, the kernel could be made to hang for long periods of time, resulting in a denial of service.
(CVE-2006-6058)

Certain calculations in the hugetlb code were not correct. A local attacker could exploit this to cause a kernel panic, leading to a denial of service. (CVE-2007-4133)

Eric Sesterhenn and Victor Julien discovered that the hop-by-hop IPv6 extended header was not correctly validated. If a system was configured for IPv6, a remote attacker could send a specially crafted IPv6 packet and cause the kernel to panic, leading to a denial of service. This was only vulnerable in Ubuntu 7.04. (CVE-2007-4567)

Permissions were not correctly stored on JFFS2 ACLs. For systems using ACLs on JFFS2, a local attacker may gain access to private files.
(CVE-2007-4849)

Chris Evans discovered that the 802.11 network stack did not correctly handle certain QOS frames. A remote attacker on the local wireless network could send specially crafted packets that would panic the kernel, resulting in a denial of service. (CVE-2007-4997)

The Philips USB Webcam driver did not correctly handle disconnects. If a local attacker tricked another user into disconnecting a webcam unsafely, the kernel could hang or consume CPU resources, leading to a denial of service. (CVE-2007-5093)

Scott James Remnant discovered that the waitid function could be made to hang the system. A local attacker could execute a specially crafted program which would leave the system unresponsive, resulting in a denial of service. (CVE-2007-5500)

Ilpo Jarvinen discovered that it might be possible for the TCP stack to panic the kernel when receiving a crafted ACK response. Only Ubuntu 7.10 contained the vulnerable code, and it is believed not to have been exploitable. (CVE-2007-5501)

When mounting the same remote NFS share to separate local locations, the first location's mount options would apply to all subsequent mounts of the same NFS share. In some configurations, this could lead to incorrectly configured permissions, allowing local users to gain additional access to the mounted share.

Several local and remote vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service or the execution of arbitrary code. The Common Vulnerabilities and Exposures project identifies the following problems :

This is an update to DSA 1428-1 which omitted a reference to CVE-2007-5904.

  - CVE-2007-3104     Eric Sandeen provided a backport of Tejun Heo's fix for     a local denial of service vulnerability in sysfs. Under     memory pressure, a dentry structure maybe reclaimed     resulting in a bad pointer dereference causing an oops     during a readdir.

  - CVE-2007-4997     Chris Evans discovered an issue with certain drivers     that make use of the Linux kernel's ieee80211 layer. A     remote user could generate a malicious 802.11 frame that     could result in a denial of service (crash). The ipw2100     driver is known to be affected by this issue, while the     ipw2200 is believed not to be.

  - CVE-2007-5500     Scott James Remnant diagnosed a coding error in the     implementation of ptrace which could be used by a local     user to cause the kernel to enter an infinite loop.

  - CVE-2007-5904     Przemyslaw Wegrzyn discovered an issue in the CIFS     filesystem that could allow a malicious server to cause     a denial of service (crash) by overflowing a buffer.

These problems have been fixed in the stable distribution in version 2.6.18.dfsg.1-13etch5.

The following matrix lists additional packages that were rebuilt for compatibility with or to take advantage of this update :

                           Debian 4.0 (etch)           fai-kernels               1.17+etch.13etch5           user-mode-linux           2.6.18-1um-2etch.13etch5

Updated kernel packages that fix various security issues in the Red Hat Enterprise Linux 5 kernel are now available.

This update has been rated as having important security impact by the Red Hat Security Response Team.

The Linux kernel handles the basic functions of the operating system.

These new kernel packages contain fixes for the following security issues :

A memory leak was found in the Red Hat Content Accelerator kernel patch. A local user could use this flaw to cause a denial of service (memory exhaustion). (CVE-2007-5494, Important)

A flaw was found in the handling of IEEE 802.11 frames affecting several wireless LAN modules. In certain circumstances, a remote attacker could trigger this flaw by sending a malicious packet over a wireless network and cause a denial of service (kernel crash).
(CVE-2007-4997, Important).

A flaw was found in the Advanced Linux Sound Architecture (ALSA). A local user who had the ability to read the /proc/driver/snd-page-alloc file could see portions of kernel memory. (CVE-2007-4571, Moderate).

In addition to the security issues described above, several bug fixes preventing possible memory corruption, system crashes, SCSI I/O fails, networking drivers performance regression and journaling block device layer issue were also included.

Red Hat Enterprise Linux 5 users are advised to upgrade to these packages, which contain backported patches to resolve these issues.

Red Hat would like to credit Vasily Averin, Chris Evans, and Neil Kettle for reporting the security issues corrected by this update.

This kernel update fixes the following security problems :

++ CVE-2006-6058: A local denial of service when mounting MINIX filesystems was fixed.

++ CVE-2007-4997: A 2 byte buffer underflow in the ieee80211 stack was fixed, which might be used by attackers in WLAN reach to crash the machine.

and the following non security bugs :
