Common Attack Pattern Enumeration and Classification (CAPEC)

  • Buffer Overflow via Environment Variables
    This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
  • Overflow Buffers
    Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
  • Client-side Injection-induced Buffer Overflow
    This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
  • Filter Failure through Buffer Overflow
    In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
  • MIME Conversion
    An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

    descriptionThis update for the Linux Kernel 3.12.51-52_34 fixes several issues. The following security bugs were fixed : - CVE-2016-4470: The key_reject_and_link function in security/keys/key.c in the Linux kernel did not ensure that a certain data structure is initialized, which allowed local users to cause a denial of service (system crash) via vectors involving a crafted keyctl request2 command (bsc#984764). - CVE-2016-1583: The ecryptfs_privileged_open function in fs/ecryptfs/kthread.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (stack memory consumption) via vectors involving crafted mmap calls for /proc pathnames, leading to recursive pagefault handling (bsc#983144). - CVE-2016-4565: The InfiniBand (aka IB) stack in the Linux kernel incorrectly relied on the write system call, which allowed local users to cause a denial of service (kernel memory write operation) or possibly have unspecified other impact via a uAPI interface (bsc#980883). - CVE-2016-0758: Integer overflow in lib/asn1_decoder.c in the Linux kernel allowed local users to gain privileges via crafted ASN.1 data (bsc#980856). - CVE-2016-2053: The asn1_ber_decoder function in lib/asn1_decoder.c in the Linux kernel allowed attackers to cause a denial of service (panic) via an ASN.1 BER file that lacks a public key, leading to mishandling by the public_key_verify_signature function in crypto/asymmetric_keys/public_key.c (bsc#979074). - CVE-2015-8816: The hub_activate function in drivers/usb/core/hub.c in the Linux kernel did not properly maintain a hub-interface data structure, which allowed physically proximate attackers to cause a denial of service (invalid memory access and system crash) or possibly have unspecified other impact by unplugging a USB hub device (bsc#979064). - CVE-2016-3134: The netfilter subsystem in the Linux kernel did not validate certain offset fields, which allowed local users to gain privileges or cause a denial of service (heap memory corruption) via an IPT_SO_SET_REPLACE setsockopt call (bsc#971793). - CVE-2013-7446: Use-after-free vulnerability in net/unix/af_unix.c in the Linux kernel allowed local users to bypass intended AF_UNIX socket permissions or cause a denial of service (panic) via crafted epoll_ctl calls (bsc#973570, bsc#955837). Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    "Justin Yackoski discovered that the Atheros L2 Ethernet Driver in the
    Linux kernel incorrectly enables scatter/gather I/O. A remote attacker
    could use this to obtain potentially sensitive information from kernel
    memory. (CVE-2016-2117)
    
    Jann Horn discovered that eCryptfs improperly attempted to use the
    mmap() handler of a lower filesystem that did not implement one,
    causing a recursive page fault to occur. A local unprivileged attacker
    could use to cause a denial of service (system crash) or possibly
    execute arbitrary code with administrative privileges. (CVE-2016-1583)
    
    Multiple race conditions where discovered in the Linux kernel's ext4
    file system. A local user could exploit this flaw to cause a denial of
    service (disk corruption) by writing to a page that is associated with
    a different users file after unsynchronized hole punching and
    page-fault handling. (CVE-2015-8839)
    
    Ralf Spenneberg discovered that the Linux kernel's GTCO digitizer USB
    device driver did not properly validate endpoint descriptors. An
    attacker with physical access could use this to cause a denial of
    service (system crash). (CVE-2016-2187)
    
    Vitaly Kuznetsov discovered that the Linux kernel did not properly
    suppress hugetlbfs support in X86 paravirtualized guests. An attacker
    in the guest OS could cause a denial of service (guest system crash).
    (CVE-2016-3961)
    
    Kangjie Lu discovered an information leak in the ANSI/IEEE 802.2 LLC
    type 2 Support implementations in the Linux kernel. A local attacker
    could use this to obtain potentially sensitive information from kernel
    memory. (CVE-2016-4485)
    
    Kangjie Lu discovered an information leak in the routing netlink
    socket interface (rtnetlink) implementation in the Linux kernel. A
    local attacker could use this to obtain potentially sensitive
    information from kernel memory. (CVE-2016-4486)
    
    Jann Horn discovered that the extended Berkeley Packet Filter (eBPF)
    implementation in the Linux kernel could overflow reference counters
    on systems with more than 32GB of physical ram and with RLIMIT_MEMLOCK
    set to infinite. A local unprivileged attacker could use to create a
    use-after- free situation, causing a denial of service (system crash)
    or possibly gain administrative privileges. (CVE-2016-4558)
    
    Jann Horn discovered that the InfiniBand interfaces within the Linux
    kernel could be coerced into overwriting kernel memory. A local
    unprivileged attacker could use this to possibly gain administrative
    privileges on systems where InifiniBand related kernel modules are
    loaded. (CVE-2016-4565)
    
    It was discovered that in some situations the Linux kernel did not
    handle propagated mounts correctly. A local unprivileged attacker
    could use this to cause a denial of service (system crash).
    (CVE-2016-4581).

  • NASL familyRed Hat Local Security Checks
    NASL idREDHAT-RHSA-2016-2766.NASL
    descriptionAn update for kernel is now available for Red Hat Enterprise Linux 6. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es) : * It was found that stacking a file system over procfs in the Linux kernel could lead to a kernel stack overflow due to deep nesting, as demonstrated by mounting ecryptfs over procfs and creating a recursion by mapping /proc/ environ. An unprivileged, local user could potentially use this flaw to escalate their privileges on the system. (CVE-2016-1583, Important) * It was reported that on s390x, the fork of a process with four page table levels will cause memory corruption with a variety of symptoms. All processes are created with three level page table and a limit of 4TB for the address space. If the parent process has four page table levels with a limit of 8PB, the function that duplicates the address space will try to copy memory areas outside of the address space limit for the child process. (CVE-2016-2143, Moderate) Bug Fix(es) : * Use of a multi-threaded workload with high memory mappings sometiems caused a kernel panic, due to a race condition between the context switch and the pagetable upgrade. This update fixes the switch_mm() by using the complete asce parameter instead of the asce_bits parameter. As a result, the kernel no longer panics in the described scenario. (BZ#1377472) * When iptables created the Transmission Control Protocol (TCP) reset packet, a kernel crash could occur due to uninitialized pointer to the TCP header within the Socket Buffer (SKB). This update fixes the transport header pointer in TCP reset for both IPv4 and IPv6, and the kernel no longer crashes in the described situation.(BZ#1372266) * Previously, when the Enhanced Error Handling (EEH) mechanism did not block the PCI configuration space access and an error was detected, a kernel panic occurred. This update fixes EEH to fix this problem. As a result, the kernel no longer panics in the described scenario. (BZ#1379596) * When the lockd service failed to start up completely, the notifier blocks were in some cases registered on a notification chain multiple times, which caused the occurrence of a circular list on the notification chain. Consequently, a soft lock-up or a kernel oops occurred. With this update, the notifier blocks are unregistered if lockd fails to start up completely, and the soft lock-ups or the kernel oopses no longer occur under the described circumstances. (BZ#1375637) * When the Fibre Channel over Ethernet (FCoE) was configured, the FCoE MaxFrameSize parameter was incorrectly restricted to 1452. With this update, the NETIF_F_ALL_FCOE symbol is no longer ignored, which fixes this bug. MaxFrameSize is now restricted to 2112, which is the correct value. (BZ#1381592) * When the fnic driver was installed on Cisco UCS Blade Server, the discs were under certain circumstances put into the offline state with the following error message:

    NASL idSL_20161115_KERNEL_ON_SL6_X.NASL
    descriptionSecurity Fix(es) : - It was found that stacking a file system over procfs in the Linux kernel could lead to a kernel stack overflow due to deep nesting, as demonstrated by mounting ecryptfs over procfs and creating a recursion by mapping /proc/environ. An unprivileged, local user could potentially use this flaw to escalate their privileges on the system. (CVE-2016-1583, Important) - It was reported that on s390x, the fork of a process with four page table levels will cause memory corruption with a variety of symptoms. All processes are created with three level page table and a limit of 4TB for the address space. If the parent process has four page table levels with a limit of 8PB, the function that duplicates the address space will try to copy memory areas outside of the address space limit for the child process. (CVE-2016-2143, Moderate) Bug Fix(es) : - Use of a multi-threaded workload with high memory mappings sometiems caused a kernel panic, due to a race condition between the context switch and the pagetable upgrade. This update fixes the switch_mm() by using the complete asce parameter instead of the asce_bits parameter. As a result, the kernel no longer panics in the described scenario. - When iptables created the Transmission Control Protocol (TCP) reset packet, a kernel crash could occur due to uninitialized pointer to the TCP header within the Socket Buffer (SKB). This update fixes the transport header pointer in TCP reset for both IPv4 and IPv6, and the kernel no longer crashes in the described situation. - Previously, when the Enhanced Error Handling (EEH) mechanism did not block the PCI configuration space access and an error was detected, a kernel panic occurred. This update fixes EEH to fix this problem. As a result, the kernel no longer panics in the described scenario. - When the lockd service failed to start up completely, the notifier blocks were in some cases registered on a notification chain multiple times, which caused the occurrence of a circular list on the notification chain. Consequently, a soft lock-up or a kernel oops occurred. With this update, the notifier blocks are unregistered if lockd fails to start up completely, and the soft lock-ups or the kernel oopses no longer occur under the described circumstances. - When the Fibre Channel over Ethernet (FCoE) was configured, the FCoE MaxFrameSize parameter was incorrectly restricted to 1452. With this update, the NETIF_F_ALL_FCOE symbol is no longer ignored, which fixes this bug. MaxFrameSize is now restricted to 2112, which is the correct value. - When the fnic driver was installed on Cisco UCS Blade Server, the discs were under certain circumstances put into the offline state with the following error message:

    descriptionThe SUSE Linux Enterprise 12 SP1 kernel was updated to 3.12.59 to receive various security and bugfixes. Main feature additions : - Improved support for Clustered File System (CephFS, fate#318586). - Addition of kGraft patches now produces logging messages to simplify auditing (fate#317827). The following security bugs were fixed : - CVE-2016-1583: Prevent the usage of mmap when the lower file system does not allow it. This could have lead to local privilege escalation when ecryptfs-utils was installed and /sbin/mount.ecryptfs_private was setuid (bsc#983143). - CVE-2014-9717: fs/namespace.c in the Linux kernel processes MNT_DETACH umount2 system calls without verifying that the MNT_LOCKED flag is unset, which allowed local users to bypass intended access restrictions and navigate to filesystem locations beneath a mount by calling umount2 within a user namespace (bnc#928547). - CVE-2016-2185: The ati_remote2_probe function in drivers/input/misc/ati_remote2.c in the Linux kernel allowed physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a crafted endpoints value in a USB device descriptor (bnc#971124). - CVE-2016-2186: The powermate_probe function in drivers/input/misc/powermate.c in the Linux kernel allowed physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a crafted endpoints value in a USB device descriptor (bnc#970958). - CVE-2016-2188: The iowarrior_probe function in drivers/usb/misc/iowarrior.c in the Linux kernel allowed physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a crafted endpoints value in a USB device descriptor (bnc#970956). - CVE-2016-2847: fs/pipe.c in the Linux kernel did not limit the amount of unread data in pipes, which allowed local users to cause a denial of service (memory consumption) by creating many pipes with non-default sizes (bsc#970948). - CVE-2016-3134: The netfilter subsystem in the Linux kernel did not validate certain offset fields, which allowed local users to gain privileges or cause a denial of service (heap memory corruption) via an IPT_SO_SET_REPLACE setsockopt call (bnc#971126 971793). - CVE-2016-3136: The mct_u232_msr_to_state function in drivers/usb/serial/mct_u232.c in the Linux kernel allowed physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a crafted USB device without two interrupt-in endpoint descriptors (bnc#970955). - CVE-2016-3137: drivers/usb/serial/cypress_m8.c in the Linux kernel allowed physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a USB device without both an interrupt-in and an interrupt-out endpoint descriptor, related to the cypress_generic_port_probe and cypress_open functions (bnc#970970). - CVE-2016-3138: The acm_probe function in drivers/usb/class/cdc-acm.c in the Linux kernel allowed physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a USB device without both a control and a data endpoint descriptor (bnc#970911 970970). - CVE-2016-3140: The digi_port_init function in drivers/usb/serial/digi_acceleport.c in the Linux kernel allowed physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a crafted endpoints value in a USB device descriptor (bnc#970892). - CVE-2016-3689: The ims_pcu_parse_cdc_data function in drivers/input/misc/ims-pcu.c in the Linux kernel allowed physically proximate attackers to cause a denial of service (system crash) via a USB device without both a master and a slave interface (bnc#971628). - CVE-2016-3951: Double free vulnerability in drivers/net/usb/cdc_ncm.c in the Linux kernel allowed physically proximate attackers to cause a denial of service (system crash) or possibly have unspecified other impact by inserting a USB device with an invalid USB descriptor (bnc#974418). - CVE-2016-4482: Fixed information leak in devio (bnc#978401). - CVE-2016-4486: Fixed information leak in rtnetlink ( bsc#978822). - CVE-2016-4569: Fixed information leak in events via snd_timer_user_tinterrupt (bsc#979213).

    NASL idVIRTUOZZO_VZA-2016-104.NASL
    descriptionAccording to the versions of the parallels-server-bm-release / vzkernel / etc packages installed, the Virtuozzo installation on the remote host is affected by the following vulnerabilities : - Stack overflow via ecryptfs and /proc/$pid/environ. It was found that stacking a file system over procfs in the Linux kernel could lead to a kernel stack overflow due to deep nesting, as demonstrated by mounting ecryptfs over procfs and creating a recursion by mapping /proc/environ. An unprivileged, local user could potentially use this flaw to escalate their privileges on the system. - Use after free in tcp_xmit_retransmit_queue. A use after free vulnerability was found in tcp_xmit_retransmit_queue and other tcp_* functions. This condition could allow an attacker to send an incorrect selective acknowledgment to existing connections, possibly resetting a connection. - block: fix use-after-free in seq file. Use-after-free vulnerability in the disk_seqf_stop function in block/genhd.c in the Linux kernel before 4.7.1 allows local users to gain privileges by leveraging the execution of a certain stop operation even if the corresponding start operation had failed. - block: fix use-after-free in sys_ioprio_get(). Race condition in the get_task_ioprio function in block/ioprio.c in the Linux kernel before 4.6.6 allows local users to gain privileges or cause a denial of service (use-after-free) via a crafted ioprio_get system call. Note that Tenable Network Security has extracted the preceding description block directly from the Virtuozzo security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    descriptionFrom Red Hat Security Advisory 2016:2766 : An update for kernel is now available for Red Hat Enterprise Linux 6. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es) : * It was found that stacking a file system over procfs in the Linux kernel could lead to a kernel stack overflow due to deep nesting, as demonstrated by mounting ecryptfs over procfs and creating a recursion by mapping /proc/ environ. An unprivileged, local user could potentially use this flaw to escalate their privileges on the system. (CVE-2016-1583, Important) * It was reported that on s390x, the fork of a process with four page table levels will cause memory corruption with a variety of symptoms. All processes are created with three level page table and a limit of 4TB for the address space. If the parent process has four page table levels with a limit of 8PB, the function that duplicates the address space will try to copy memory areas outside of the address space limit for the child process. (CVE-2016-2143, Moderate) Bug Fix(es) : * Use of a multi-threaded workload with high memory mappings sometiems caused a kernel panic, due to a race condition between the context switch and the pagetable upgrade. This update fixes the switch_mm() by using the complete asce parameter instead of the asce_bits parameter. As a result, the kernel no longer panics in the described scenario. (BZ#1377472) * When iptables created the Transmission Control Protocol (TCP) reset packet, a kernel crash could occur due to uninitialized pointer to the TCP header within the Socket Buffer (SKB). This update fixes the transport header pointer in TCP reset for both IPv4 and IPv6, and the kernel no longer crashes in the described situation.(BZ#1372266) * Previously, when the Enhanced Error Handling (EEH) mechanism did not block the PCI configuration space access and an error was detected, a kernel panic occurred. This update fixes EEH to fix this problem. As a result, the kernel no longer panics in the described scenario. (BZ#1379596) * When the lockd service failed to start up completely, the notifier blocks were in some cases registered on a notification chain multiple times, which caused the occurrence of a circular list on the notification chain. Consequently, a soft lock-up or a kernel oops occurred. With this update, the notifier blocks are unregistered if lockd fails to start up completely, and the soft lock-ups or the kernel oopses no longer occur under the described circumstances. (BZ#1375637) * When the Fibre Channel over Ethernet (FCoE) was configured, the FCoE MaxFrameSize parameter was incorrectly restricted to 1452. With this update, the NETIF_F_ALL_FCOE symbol is no longer ignored, which fixes this bug. MaxFrameSize is now restricted to 2112, which is the correct value. (BZ#1381592) * When the fnic driver was installed on Cisco UCS Blade Server, the discs were under certain circumstances put into the offline state with the following error message:

This update fixes memory management in the Linux kernel by backporting an upstream patch that enlarges the stack guard page gap. As a result, mmap now works as expected under the described circumstances. (BZ#1474721)

    descriptionThis update for the Linux Kernel 3.12.55-52_42 fixes several issues. The following security bugs were fixed : - CVE-2016-4470: The key_reject_and_link function in security/keys/key.c in the Linux kernel did not ensure that a certain data structure is initialized, which allowed local users to cause a denial of service (system crash) via vectors involving a crafted keyctl request2 command (bsc#984764). - CVE-2016-1583: The ecryptfs_privileged_open function in fs/ecryptfs/kthread.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (stack memory consumption) via vectors involving crafted mmap calls for /proc pathnames, leading to recursive pagefault handling (bsc#983144). - CVE-2016-4565: The InfiniBand (aka IB) stack in the Linux kernel incorrectly relied on the write system call, which allowed local users to cause a denial of service (kernel memory write operation) or possibly have unspecified other impact via a uAPI interface (bsc#980883). - CVE-2016-0758: Integer overflow in lib/asn1_decoder.c in the Linux kernel allowed local users to gain privileges via crafted ASN.1 data (bsc#980856). - CVE-2016-2053: The asn1_ber_decoder function in lib/asn1_decoder.c in the Linux kernel allowed attackers to cause a denial of service (panic) via an ASN.1 BER file that lacks a public key, leading to mishandling by the public_key_verify_signature function in crypto/asymmetric_keys/public_key.c (bsc#979074). - CVE-2015-8816: The hub_activate function in drivers/usb/core/hub.c in the Linux kernel did not properly maintain a hub-interface data structure, which allowed physically proximate attackers to cause a denial of service (invalid memory access and system crash) or possibly have unspecified other impact by unplugging a USB hub device (bsc#979064). - CVE-2016-3134: The netfilter subsystem in the Linux kernel did not validate certain offset fields, which allowed local users to gain privileges or cause a denial of service (heap memory corruption) via an IPT_SO_SET_REPLACE setsockopt call (bsc#971793). - CVE-2013-7446: Use-after-free vulnerability in net/unix/af_unix.c in the Linux kernel allowed local users to bypass intended AF_UNIX socket permissions or cause a denial of service (panic) via crafted epoll_ctl calls (bsc#973570, bsc#955837). Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    descriptionAn update for kernel is now available for Red Hat Enterprise Linux 6. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es) : * It was found that stacking a file system over procfs in the Linux kernel could lead to a kernel stack overflow due to deep nesting, as demonstrated by mounting ecryptfs over procfs and creating a recursion by mapping /proc/ environ. An unprivileged, local user could potentially use this flaw to escalate their privileges on the system. (CVE-2016-1583, Important) * It was reported that on s390x, the fork of a process with four page table levels will cause memory corruption with a variety of symptoms. All processes are created with three level page table and a limit of 4TB for the address space. If the parent process has four page table levels with a limit of 8PB, the function that duplicates the address space will try to copy memory areas outside of the address space limit for the child process. (CVE-2016-2143, Moderate) Bug Fix(es) : * Use of a multi-threaded workload with high memory mappings sometiems caused a kernel panic, due to a race condition between the context switch and the pagetable upgrade. This update fixes the switch_mm() by using the complete asce parameter instead of the asce_bits parameter. As a result, the kernel no longer panics in the described scenario. (BZ#1377472) * When iptables created the Transmission Control Protocol (TCP) reset packet, a kernel crash could occur due to uninitialized pointer to the TCP header within the Socket Buffer (SKB). This update fixes the transport header pointer in TCP reset for both IPv4 and IPv6, and the kernel no longer crashes in the described situation.(BZ#1372266) * Previously, when the Enhanced Error Handling (EEH) mechanism did not block the PCI configuration space access and an error was detected, a kernel panic occurred. This update fixes EEH to fix this problem. As a result, the kernel no longer panics in the described scenario. (BZ#1379596) * When the lockd service failed to start up completely, the notifier blocks were in some cases registered on a notification chain multiple times, which caused the occurrence of a circular list on the notification chain. Consequently, a soft lock-up or a kernel oops occurred. With this update, the notifier blocks are unregistered if lockd fails to start up completely, and the soft lock-ups or the kernel oopses no longer occur under the described circumstances. (BZ#1375637) * When the Fibre Channel over Ethernet (FCoE) was configured, the FCoE MaxFrameSize parameter was incorrectly restricted to 1452. With this update, the NETIF_F_ALL_FCOE symbol is no longer ignored, which fixes this bug. MaxFrameSize is now restricted to 2112, which is the correct value. (BZ#1381592) * When the fnic driver was installed on Cisco UCS Blade Server, the discs were under certain circumstances put into the offline state with the following error message:
