Summary

The llc_ui_getname function in net/llc/af_llc.c in the Linux kernel 2.6.31-rc7 and earlier does not initialize a certain data structure, which allows local users to read the contents of some kernel memory locations by calling getsockname on an AF_LLC socket.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Subverting Environment Variable Values
    The attacker directly or indirectly modifies environment variables used by or controlling the target software. The attacker's goal is to cause the target software to deviate from its expected operation in a manner that benefits the attacker.
  • Footprinting
    An attacker engages in probing and exploration activity to identify constituents and properties of the target. Footprinting is a general term to describe a variety of information gathering techniques, often used by attackers in preparation for some attack. It consists of using tools to learn as much as possible about the composition, configuration, and security mechanisms of the targeted application, system or network. Information that might be collected during a footprinting effort could include open ports, applications and their versions, network topology, and similar information. While footprinting is not intended to be damaging (although certain activities, such as network scans, can sometimes cause disruptions to vulnerable applications inadvertently) it may often pave the way for more damaging attacks.
  • Exploiting Trust in Client (aka Make the Client Invisible)
    An attack of this type exploits a programs' vulnerabilities in client/server communication channel authentication and data integrity. It leverages the implicit trust a server places in the client, or more importantly, that which the server believes is the client. An attacker executes this type of attack by placing themselves in the communication channel between client and server such that communication directly to the server is possible where the server believes it is communicating only with a valid client. There are numerous variations of this type of attack.
  • Browser Fingerprinting
    An attacker carefully crafts small snippets of Java Script to efficiently detect the type of browser the potential victim is using. Many web-based attacks need prior knowledge of the web browser including the version of browser to ensure successful exploitation of a vulnerability. Having this knowledge allows an attacker to target the victim with attacks that specifically exploit known or zero day weaknesses in the type and version of the browser used by the victim. Automating this process via Java Script as a part of the same delivery system used to exploit the browser is considered more efficient as the attacker can supply a browser fingerprinting method and integrate it with exploit code, all contained in Java Script and in response to the same web page request by the browser.
  • Session Credential Falsification through Prediction
    This attack targets predictable session ID in order to gain privileges. The attacker can predict the session ID used during a transaction to perform spoofing and session hijacking.

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

  - CVE-2009-2846
    Michael Buesch noticed a typing issue in the eisa-eeprom
    driver for the hppa architecture. Local users could
    exploit this issue to gain access to restricted memory.

  - CVE-2009-2847
    Ulrich Drepper noticed an issue in the do_sigalstack
    routine on 64-bit systems. This issue allows local users
    to gain access to potentially sensitive memory on the
    kernel stack.

  - CVE-2009-2848
    Eric Dumazet discovered an issue in the execve path,
    where the clear_child_tid variable was not being
    properly cleared. Local users could exploit this issue
    to cause a denial of service (memory corruption).

  - CVE-2009-2849
    Neil Brown discovered an issue in the sysfs interface to
    md devices. When md arrays are not active, local users
    can exploit this vulnerability to cause a denial of
    service (oops).

  - CVE-2009-2903
    Mark Smith discovered a memory leak in the appletalk
    implementation. When the appletalk and ipddp modules are
    loaded, but no ipddp'N' device is found, remote
    attackers can cause a denial of service by consuming
    large amounts of system memory.

  - CVE-2009-2908
    Loic Minier discovered an issue in the eCryptfs
    filesystem. A local user can cause a denial of service
    (kernel oops) by causing a dentry value to go negative.

  - CVE-2009-2909
    Arjan van de Ven discovered an issue in the AX.25
    protocol implementation. A specially crafted call to
    setsockopt() can result in a denial of service (kernel
    oops).

  - CVE-2009-2910
    Jan Beulich discovered the existence of a sensitive
    kernel memory leak. Systems running the 'amd64' kernel
    do not properly sanitize registers for 32-bit processes.

  - CVE-2009-3001
    Jiri Slaby fixed a sensitive memory leak issue in the
    ANSI/IEEE 802.2 LLC implementation. This is not
    exploitable in the Debian lenny kernel as root
    privileges are required to exploit this issue.

  - CVE-2009-3002
    Eric Dumazet fixed several sensitive memory leaks in the
    IrDA, X.25 PLP (Rose), NET/ROM, Acorn Econet/AUN, and
    Controller Area Network (CAN) implementations. Local
    users can exploit these issues to gain access to kernel
    memory.

  - CVE-2009-3228
    Eric Dumazet reported an instance of uninitialized
    kernel memory in the network packet scheduler. Local
    users may be able to exploit this issue to read the
    contents of sensitive kernel memory.

  - CVE-2009-3238
    Linus Torvalds provided a change to the get_random_int()
    function to increase its randomness.

  - CVE-2009-3286
    Eric Paris discovered an issue with the NFSv4 server
    implementation. When an O_EXCL create fails, files may
    be left with corrupted permissions, possibly granting
    unintentional privileges to other local users.

  - CVE-2009-3547
    Earl Chew discovered a NULL pointer dereference issue in
    the pipe_rdwr_open function which can be used by local
    users to gain elevated privileges.

  - CVE-2009-3612

For the oldstable distribution (etch), this problem has been fixed in

Note: Debian 'etch' includes linux kernel packages based upon both the
2.6.18 and 2.6.24 linux releases. All known security issues are
carefully tracked against both packages and both packages will receive
security updates until security support for Debian 'etch' concludes.
However, given the high frequency at which low-severity security
issues are discovered in the kernel and the resource requirements of
doing an update, lower severity 2.6.18 and 2.6.24 updates will
typically release in a staggered or 'leap-frog' fashion."

    descriptionSeveral vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service, sensitive memory leak or privilege escalation. The Common Vulnerabilities and Exposures project identifies the following problems : - CVE-2009-1883 Solar Designer discovered a missing capability check in the z90crypt driver or s390 systems. This vulnerability may allow a local user to gain elevated privileges. - CVE-2009-2909 Arjan van de Ven discovered an issue in the AX.25 protocol implementation. A specially crafted call to setsockopt() can result in a denial of service (kernel oops). - CVE-2009-3001 Jiri Slaby fixed a sensitive memory leak issue in the ANSI/IEEE 802.2 LLC implementation. This is not exploitable in the Debian lenny kernel as root privileges are required to exploit this issue. - CVE-2009-3002 Eric Dumazet fixed several sensitive memory leaks in the IrDA, X.25 PLP (Rose), NET/ROM, Acorn Econet/AUN, and Controller Area Network (CAN) implementations. Local users can exploit these issues to gain access to kernel memory. - CVE-2009-3228 Eric Dumazet reported an instance of uninitialized kernel memory in the network packet scheduler. Local users may be able to exploit this issue to read the contents of sensitive kernel memory. - CVE-2009-3238 Linus Torvalds provided a change to the get_random_int() function to increase its randomness. - CVE-2009-3286 Eric Paris discovered an issue with the NFSv4 server implementation. When an O_EXCL create fails, files may be left with corrupted permissions, possibly granting unintentional privileges to other local users. - CVE-2009-3547 Earl Chew discovered a NULL pointer dereference issue in the pipe_rdwr_open function which can be used by local users to gain elevated privileges. - CVE-2009-3612 Jiri Pirko discovered a typo in the initialization of a structure in the netlink subsystem that may allow local users to gain access to sensitive kernel memory. - CVE-2009-3621 Tomoki Sekiyama discovered a deadlock condition in the UNIX domain socket implementation. Local users can exploit this vulnerability to cause a denial of service (system hang).

"Upgrade the linux-2.6, fai-kernels, and user-mode-linux packages.

For the oldstable distribution (etch), this problem has been fixed in
version 2.6.18.dfsg.1-26etch1.

Note: Debian 'etch' includes linux kernel packages based upon both the
2.6.18 and 2.6.24 linux releases. All known security issues are
carefully tracked against both packages and both packages will receive
security updates until security support for Debian 'etch' concludes.
However, given the high frequency at which low-severity security
issues are discovered in the kernel and the resource requirements of
doing an update, lower severity 2.6.18 and 2.6.24 updates will
typically release in a staggered or 'leap-frog' fashion.

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

CVE-2009-3547 kernel: fs: pipe.c NULL pointer dereference

Security fixes :

  - when fput() was called to close a socket, the
    __scm_destroy() function in the Linux kernel could make
    indirect recursive calls to itself. This
    could,potentially, lead to a denial of service issue.
    (CVE-2008-5029, Important)

  - the sendmsg() function in the Linux kernel did not block
    during UNIX socket garbage collection. This could,
    potentially, lead to a local denial of service.
    (CVE-2008-5300, Important)

  - the exit_notify() function in the Linux kernel did not
    properly reset the exit signal if a process executed a
    set user ID (setuid) application before exiting. This
    could allow a local, unprivileged user to elevate their
    privileges. (CVE-2009-1337, Important)

  - a flaw was found in the Intel PRO/1000 network driver in
    the Linux kernel. Frames with sizes near the MTU of an
    interface may be split across multiple hardware receive
    descriptors. Receipt of such a frame could leak through
    a validation check, leading to a corruption of the
    length check. A remote attacker could use this flaw to
    send a specially crafted packet that would cause a
    denial of service or code execution. (CVE-2009-1385,
    Important)

  - the ADDR_COMPAT_LAYOUT and MMAP_PAGE_ZERO flags were not
    cleared when a setuid or setgid program was executed. A
    local, unprivileged user could use this flaw to bypass
    the mmap_min_addr protection mechanism and perform a
    NULL pointer dereference attack, or bypass the Address
    Space Layout Randomization (ASLR) security feature.
    (CVE-2009-1895, Important)

  - it was discovered that, when executing a new process,
    the clear_child_tid pointer in the Linux kernel is not
    cleared. If this pointer points to a writable portion of
    the memory of the new program, the kernel could corrupt
    four bytes of memory, possibly leading to a local denial
    of service or privilege escalation. (CVE-2009-2848,
    Important)

  - missing initialization flaws were found in getname()
    implementations in the IrDA sockets, AppleTalk DDP
    protocol, NET/ROM protocol, and ROSE protocol
    implementations in the Linux kernel. Certain data
    structures in these getname() implementations were not
    initialized properly before being copied to user-space.
    These flaws could lead to an information leak.
    (CVE-2009-3002, Important)

  - a NULL pointer dereference flaw was found in each of the
    following functions in the Linux kernel:
    pipe_read_open(), pipe_write_open(), and
    pipe_rdwr_open(). When the mutex lock is not held, the
    i_pipe pointer could be released by other processes
    before it is used to update the pipe's reader and writer
    counters. This could lead to a local denial of service
    or privilege escalation. (CVE-2009-3547, Important)

Bug fixes :

  - this update adds the mmap_min_addr tunable and
    restriction checks to help prevent unprivileged users
    from creating new memory mappings below the minimum
    address. This can help prevent the exploitation of NULL
    pointer dereference bugs. Note that mmap_min_addr is set
    to zero (disabled) by default for backwards
    compatibility. (BZ#512642)

  - a bridge reference count problem in IPv6 has been fixed.
    (BZ#457010)

  - enforce null-termination of user-supplied arguments to
    setsockopt(). (BZ#505514)

  - the gcc flag '-fno-delete-null-pointer-checks' was added
    to the kernel build options. This prevents gcc from
    optimizing out NULL pointer checks after the first use
    of a pointer. NULL pointer bugs are often exploited by
    attackers. Keeping these checks is a safety measure.
    (BZ#511185)

  - a check has been added to the IPv4 code to make sure
    that rt is not NULL, to help prevent future bugs in
    functions that call ip_append_data() from being
    exploitable. (BZ#520300)

The system must be rebooted for this update to take effect."

"Notice: Debian 5.0.4, the next point release of Debian 'lenny', will
include a new default value for the mmap_min_addr tunable. This change
will add an additional safeguard against a class of security
vulnerabilities known as 'NULL pointer dereference' vulnerabilities,
but it will need to be overridden when using certain applications.
Additional information about this change, including instructions for
making this change locally in advance of 5.0.4 (recommended), can be
found at: https://wiki.debian.org/mmap_min_addr.

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

  - CVE-2009-2695
    Eric Paris provided several fixes to increase the
    protection provided by the mmap_min_addr tunable against
    NULL pointer dereference vulnerabilities.

  - CVE-2009-2903
    Mark Smith discovered a memory leak in the appletalk
    implementation. When the appletalk and ipddp modules are
    loaded, but no ipddp'N' device is found, remote
    attackers can cause a denial of service by consuming
    large amounts of system memory.

  - CVE-2009-2908
    Loic Minier discovered an issue in the eCryptfs
    filesystem. A local user can cause a denial of service
    (kernel oops) by causing a dentry value to go negative.

  - CVE-2009-2909
    Arjan van de Ven discovered an issue in the AX.25
    protocol implementation. A specially crafted call to
    setsockopt() can result in a denial of service (kernel
    oops).

  - CVE-2009-2910
    Jan Beulich discovered the existence of a sensitive
    kernel memory leak. Systems running the 'amd64' kernel
    do not properly sanitize registers for 32-bit processes.

  - CVE-2009-3001
    Jiri Slaby fixed a sensitive memory leak issue in the
    ANSI/IEEE 802.2 LLC implementation. This is not
    exploitable in the Debian lenny kernel as root
    privileges are required to exploit this issue.

  - CVE-2009-3002
    Eric Dumazet fixed several sensitive memory leaks in the
    IrDA, X.25 PLP (Rose), NET/ROM, Acorn Econet/AUN, and
    Controller Area Network (CAN) implementations. Local
    users can exploit these issues to gain access to kernel
    memory.

  - CVE-2009-3286
    Eric Paris discovered an issue with the NFSv4 server
    implementation. When an O_EXCL create fails, files may
    be left with corrupted permissions, possibly granting
    unintentional privileges to other local users.

  - CVE-2009-3290
    Jan Kiszka noticed that the kvm_emulate_hypercall
    function in KVM does not prevent access to MMU
    hypercalls from ring 0, which allows local guest OS
    users to cause a denial of service (guest kernel crash)
    and read or write guest kernel memory.

  - CVE-2009-3613
    Alistair Strachan reported an issue in the r8169 driver.
    Remote users can cause a denial of service (IOMMU space
    exhaustion and system crash) by transmitting a large
    amount of jumbo frames."

"Upgrade the linux-2.6 and user-mode-linux packages.

For the oldstable distribution (etch), these problems, where
applicable, will be fixed in updates to linux-2.6 and linux-2.6.24.

For the stable distribution (lenny), this problem has been fixed in
version 2.6.26-19lenny1.

Note: Debian carefully tracks all known security issues across every
linux kernel package in all releases under active security support.
However, given the high frequency at which low-severity security
issues are discovered in the kernel and the resource requirements of
doing an update, updates for lower priority issues will normally not
be released for all kernels at the same time. Rather, they will be
released in a staggered or 'leap-frog' fashion.

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

    descriptionSolar Designer discovered that the z90crypt driver did not correctly check capabilities. A local attacker could exploit this to shut down the device, leading to a denial of service. Only affected Ubuntu 6.06. (CVE-2009-1883) Michael Buesch discovered that the SGI GRU driver did not correctly check the length when setting options. A local attacker could exploit this to write to the kernel stack, leading to root privilege escalation or a denial of service. Only affected Ubuntu 8.10 and 9.04. (CVE-2009-2584) It was discovered that SELinux did not fully implement the mmap_min_addr restrictions. A local attacker could exploit this to allocate the NULL memory page which could lead to further attacks against kernel NULL-dereference vulnerabilities. Ubuntu 6.06 was not affected. (CVE-2009-2695) Cagri Coltekin discovered that the UDP stack did not correctly handle certain flags. A local user could send specially crafted commands and traffic to gain root privileges or crash the systeam, leading to a denial of service. Only affected Ubuntu 6.06. (CVE-2009-2698) Hiroshi Shimamoto discovered that monotonic timers did not correctly validate parameters. A local user could make a specially crafted timer request to gain root privileges or crash the system, leading to a denial of service. Only affected Ubuntu 9.04. (CVE-2009-2767) Michael Buesch discovered that the HPPA ISA EEPROM driver did not correctly validate positions. A local user could make a specially crafted request to gain root privileges or crash the system, leading to a denial of service. (CVE-2009-2846) Ulrich Drepper discovered that kernel signal stacks were not being correctly padded on 64-bit systems. A local attacker could send specially crafted calls to expose 4 bytes of kernel stack memory, leading to a loss of privacy. (CVE-2009-2847) Jens Rosenboom discovered that the clone method did not correctly clear certain fields. A local attacker could exploit this to gain privileges or crash the system, leading to a denial of service. (CVE-2009-2848) It was discovered that the MD driver did not check certain sysfs files. A local attacker with write access to /sys could exploit this to cause a system crash, leading to a denial of service. Ubuntu 6.06 was not affected. (CVE-2009-2849) Mark Smith discovered that the AppleTalk stack did not correctly manage memory. A remote attacker could send specially crafted traffic to cause the system to consume all available memory, leading to a denial of service. (CVE-2009-2903) Loic Minier discovered that eCryptfs did not correctly handle writing to certain deleted files. A local attacker could exploit this to gain root privileges or crash the system, leading to a denial of service. Ubuntu 6.06 was not affected. (CVE-2009-2908) It was discovered that the LLC, AppleTalk, IR, EConet, Netrom, and ROSE network stacks did not correctly initialize their data structures. A local attacker could make specially crafted calls to read kernel memory, leading to a loss of privacy. (CVE-2009-3001, CVE-2009-3002) It was discovered that the randomization used for Address Space Layout Randomization was predictable within a small window of time. A local attacker could exploit this to leverage further attacks that require knowledge of userspace memory layouts. (CVE-2009-3238) Eric Paris discovered that NFSv4 did not correctly handle file creation failures. An attacker with write access to an NFSv4 share could exploit this to create files with arbitrary mode bits, leading to privilege escalation or a loss of privacy. (CVE-2009-3286) Bob Tracy discovered that the SCSI generic driver did not correctly use the right index for array access. A local attacker with write access to a CDR could exploit this to crash the system, leading to a denial of service. Only Ubuntu 9.04 was affected. (CVE-2009-3288) Jan Kiszka discovered that KVM did not correctly validate certain hypercalls. A local unprivileged attacker in a virtual guest could exploit this to crash the guest kernel, leading to a denial of service. Ubuntu 6.06 was not affected. (CVE-2009-3290).
