Impact:
Exploitability:
CWE CWE-200
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.
  • Reusing Session IDs (aka Session Replay)
    This attack targets the reuse of valid session ID to spoof the target system in order to gain privileges. The attacker tries to reuse a stolen session ID used previously during a transaction to perform spoofing and session hijacking. Another name for this type of attack is Session Replay.
  • Using Slashes in Alternate Encoding
    This attack targets the encoding of the Slash characters. An attacker would try to exploit common filtering problems related to the use of the slashes characters to gain access to resources on the target host. Directory-driven systems, such as file systems and databases, typically use the slash character to indicate traversal between directories or other container components. For murky historical reasons, PCs (and, as a result, Microsoft OSs) choose to use a backslash, whereas the UNIX world typically makes use of the forward slash. The schizophrenic result is that many MS-based systems are required to understand both forms of the slash. This gives the attacker many opportunities to discover and abuse a number of common filtering problems. The goal of this pattern is to discover server software that only applies filters to one version, but not the other.

(bsc#979548) - CVE-2016-4805: Use-after-free vulnerability in drivers/net/ppp/ppp_generic.c in the Linux kernel allowed local users to cause a denial of service (memory corruption and system crash, or spinlock) or possibly have unspecified other impact by removing a network namespace, related to the ppp_register_net_channel and ppp_unregister_channel functions. (bsc#980371). - CVE-2016-4951: The tipc_nl_publ_dump function in net/tipc/socket.c in the Linux kernel did not verify socket existence, which allowed local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a dumpit operation. (bsc#981058). - CVE-2016-5244: An information leak vulnerability in function rds_inc_info_copy of file net/rds/recv.c was fixed that might have leaked kernel stack data. (bsc#983213). - CVE-2016-4580: The x25_negotiate_facilities function in net/x25/x25_facilities.c in the Linux kernel did not properly initialize a certain data structure, which allowed attackers to obtain sensitive information from kernel stack memory via an X.25 Call Request. (bsc#981267). - CVE-2016-0758: Tags with indefinite length could have corrupted pointers in asn1_find_indefinite_length (bsc#979867). - 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 (bnc#963762). - 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 (bnc#955654). - 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). - CVE-2016-3672: The arch_pick_mmap_layout function in arch/x86/mm/mmap.c in the Linux kernel did not properly randomize the legacy base address, which made it easier for local users to defeat the intended restrictions on the ADDR_NO_RANDOMIZE flag, and bypass the ASLR protection mechanism for a setuid or setgid program, by disabling stack-consumption resource limits (bnc#974308). - CVE-2016-4482: A kernel information leak in the usbfs devio connectinfo was fixed, which could expose kernel stack memory to userspace. (bnc#978401). - CVE-2016-4485: A kernel information leak in llc was fixed (bsc#978821). - CVE-2016-4486: A kernel information leak in rtnetlink was fixed, where 4 uninitialized bytes could leak to userspace (bsc#978822). - CVE-2016-4557: A use-after-free via double-fdput in replace_map_fd_with_map_ptr() was fixed, which could allow privilege escalation (bsc#979018). - CVE-2016-4565: When the 'rdma_ucm' infiniband module is loaded, local attackers could escalate their privileges (bsc#979548). - CVE-2016-4569: A kernel information leak in the ALSA timer via events via snd_timer_user_tinterrupt that could leak information to userspace was fixed (bsc#979213). - CVE-2016-4578: A kernel information leak in the ALSA timer via events that could leak information to userspace was fixed (bsc#979879). - CVE-2016-4581: If the first propogated mount copy was being a slave it could oops the kernel (bsc#979913) The following non-security bugs were fixed : - ALSA: hda - Add dock support for ThinkPad X260 (boo#979278). - ALSA: hda - Apply fix for white noise on Asus N550JV, too (boo#979278). - ALSA: hda - Asus N750JV external subwoofer fixup (boo#979278). - ALSA: hda - Fix broken reconfig (boo#979278). - ALSA: hda - Fix headphone mic input on a few Dell ALC293 machines (boo#979278). - ALSA: hda - Fix subwoofer pin on ASUS N751 and N551 (boo#979278). - ALSA: hda - Fix white noise on Asus N750JV headphone (boo#979278). - ALSA: hda - Fix white noise on Asus UX501VW headset (boo#979278). - ALSA: hda/realtek - Add ALC3234 headset mode for Optiplex 9020m (boo#979278). - ALSA: hda/realtek - New codecs support for ALC234/ALC274/ALC294 (boo#979278). - ALSA: hda/realtek - New codec support of ALC225 (boo#979278). - ALSA: hda/realtek - Support headset mode for ALC225 (boo#979278). - ALSA: pcxhr: Fix missing mutex unlock (boo#979278). - ALSA: usb-audio: Quirk for yet another Phoenix Audio devices (v2) (boo#979278). - bluetooth: fix power_on vs close race (bsc#966849). - bluetooth: vhci: fix open_timeout vs. hdev race (bsc#971799,bsc#966849). - bluetooth: vhci: Fix race at creating hci device (bsc#971799,bsc#966849). - bluetooth: vhci: purge unhandled skbs (bsc#971799,bsc#966849). - btrfs: do not use src fd for printk (bsc#980348). - btrfs: fix crash/invalid memory access on fsync when using overlayfs (bsc#977198) - drm: qxl: Workaround for buggy user-space (bsc#981344). - enic: set netdev->vlan_features (bsc#966245). - fs: add file_dentry() (bsc#977198). - IB/IPoIB: Do not set skb truesize since using one linearskb (bsc#980657). - input: i8042 - lower log level for 'no controller' message (bsc#945345). - kabi: Add kabi/severities entries to ignore sound/hda/*, x509_*, efivar_validate, file_open_root and dax_fault - kabi: Add some fixups (module, pci_dev, drm, fuse and thermal) - kabi: file_dentry changes (bsc#977198). - kABI fixes for 4.1.22 - mm/page_alloc.c: calculate 'available' memory in a separate function (bsc#982239). - net: disable fragment reassembly if high_thresh is zero (bsc#970506). - of: iommu: Silence misleading warning. - pstore_register() error handling was wrong -- it tried to release lock before it's acquired, causing spinlock / preemption imbalance. - usb: quirk to stop runtime PM for Intel 7260 (bnc#984460). - Revert 'usb: hub: do not clear BOS field during reset device' (boo#979728). - usb: core: hub: hub_port_init lock controller instead of bus (bnc#978073). - usb: preserve kABI in address0 locking (bnc#978073). - usb: usbip: fix potential out-of-bounds write (bnc#975945). - USB: xhci: Add broken streams quirk for Frescologic device id 1009 (bnc#982712). - virtio_balloon: do not change memory amount visible via /proc/meminfo (bsc#982238). - virtio_balloon: export 'available' memory to balloon statistics (bsc#982239).

  • NASL family Debian Local Security Checks
    NASL id DEBIAN_DSA-3607.NASL
    description Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks. - CVE-2015-7515, CVE-2016-2184, CVE-2016-2185, CVE-2016-2186, CVE-2016-2187, CVE-2016-3136, CVE-2016-3137, CVE-2016-3138, CVE-2016-3140 Ralf Spenneberg of OpenSource Security reported that various USB drivers do not sufficiently validate USB descriptors. This allowed a physically present user with a specially designed USB device to cause a denial of service (crash). - CVE-2016-0821 Solar Designer noted that the list 'poisoning' feature, intended to mitigate the effects of bugs in list manipulation in the kernel, used poison values within the range of virtual addresses that can be allocated by user processes. - CVE-2016-1237 David Sinquin discovered that nfsd does not check permissions when setting ACLs, allowing users to grant themselves permissions to a file by setting the ACL. - CVE-2016-1583 Jann Horn of Google Project Zero reported that the eCryptfs filesystem could be used together with the proc filesystem to cause a kernel stack overflow. If the ecryptfs-utils package is installed, local users could exploit this, via the mount.ecryptfs_private program, for denial of service (crash) or possibly for privilege escalation. - CVE-2016-2117 Justin Yackoski of Cryptonite discovered that the Atheros L2 ethernet driver incorrectly enables scatter/gather I/O. A remote attacker could take advantage of this flaw to obtain potentially sensitive information from kernel memory. - CVE-2016-2143 Marcin Koscielnicki discovered that the fork implementation in the Linux kernel on s390 platforms mishandles the case of four page-table levels, which allows local users to cause a denial of service (system crash). - CVE-2016-3070 Jan Stancek of Red Hat discovered a local denial of service vulnerability in AIO handling. - CVE-2016-3134 The Google Project Zero team found that the netfilter subsystem does not sufficiently validate filter table entries. A user with the CAP_NET_ADMIN capability could use this for denial of service (crash) or possibly for privilege escalation. Debian disables unprivileged user namespaces by default, if locally enabled with the kernel.unprivileged_userns_clone sysctl, this allows privilege escalation. - CVE-2016-3156 Solar Designer discovered that the IPv4 implementation in the Linux kernel did not perform the destruction of inet device objects properly. An attacker in a guest OS could use this to cause a denial of service (networking outage) in the host OS. - CVE-2016-3157 / XSA-171 Andy Lutomirski discovered that the x86_64 (amd64) task switching implementation did not correctly update the I/O permission level when running as a Xen paravirtual (PV) guest. In some configurations this would allow local users to cause a denial of service (crash) or to escalate their privileges within the guest. - CVE-2016-3672 Hector Marco and Ismael Ripoll noted that it was possible to disable Address Space Layout Randomisation (ASLR) for x86_32 (i386) programs by removing the stack resource limit. This made it easier for local users to exploit security flaws in programs that have the setuid or setgid flag set. - CVE-2016-3951 It was discovered that the cdc_ncm driver would free memory prematurely if certain errors occurred during its initialisation. This allowed a physically present user with a specially designed USB device to cause a denial of service (crash) or possibly to escalate their privileges. - CVE-2016-3955 Ignat Korchagin reported that the usbip subsystem did not check the length of data received for a USB buffer. This allowed denial of service (crash) or privilege escalation on a system configured as a usbip client, by the usbip server or by an attacker able to impersonate it over the network. A system configured as a usbip server might be similarly vulnerable to physically present users. - CVE-2016-3961 / XSA-174 Vitaly Kuznetsov of Red Hat discovered that Linux allowed the use of hugetlbfs on x86 (i386 and amd64) systems even when running as a Xen paravirtualised (PV) guest, although Xen does not support huge pages. This allowed users with access to /dev/hugepages to cause a denial of service (crash) in the guest. - CVE-2016-4470 David Howells of Red Hat discovered that a local user can trigger a flaw in the Linux kernel's handling of key lookups in the keychain subsystem, leading to a denial of service (crash) or possibly to privilege escalation. - CVE-2016-4482, CVE-2016-4485, CVE-2016-4486, CVE-2016-4569, CVE-2016-4578, CVE-2016-4580, CVE-2016-5243, CVE-2016-5244 Kangjie Lu reported that the USB devio, llc, rtnetlink, ALSA timer, x25, tipc, and rds facilities leaked information from the kernel stack. - CVE-2016-4565 Jann Horn of Google Project Zero reported that various components in the InfiniBand stack implemented unusual semantics for the write() operation. On a system with InfiniBand drivers loaded, local users could use this for denial of service or privilege escalation. - CVE-2016-4581 Tycho Andersen discovered that in some situations the Linux kernel did not handle propagated mounts correctly. A local user can take advantage of this flaw to cause a denial of service (system crash). - CVE-2016-4805 Baozeng Ding discovered a use-after-free in the generic PPP layer in the Linux kernel. A local user can take advantage of this flaw to cause a denial of service (system crash), or potentially escalate their privileges. - CVE-2016-4913 Al Viro found that the ISO9660 filesystem implementation did not correctly count the length of certain invalid name entries. Reading a directory containing such name entries would leak information from kernel memory. Users permitted to mount disks or disk images could use this to obtain sensitive information. - CVE-2016-4997 / CVE-2016-4998 Jesse Hertz and Tim Newsham discovered that missing input sanitising in Netfilter socket handling may result in denial of service. Debian disables unprivileged user namespaces by default, if locally enabled with the kernel.unprivileged_userns_clone sysctl, this also allows privilege escalation.

  • NASL family Debian Local Security Checks
    NASL id DEBIAN_DLA-516.NASL
    description This update fixes the CVEs described below. CVE-2016-0821 Solar Designer noted that the list 'poisoning' feature, intended to mitigate the effects of bugs in list manipulation in the kernel, used poison values within the range of virtual addresses that can be allocated by user processes. CVE-2016-1583 Jann Horn of Google Project Zero reported that the eCryptfs filesystem could be used together with the proc filesystem to cause a kernel stack overflow. If the ecryptfs-utils package was installed, local users could exploit this, via the mount.ecryptfs_private program, for denial of service (crash) or possibly for privilege escalation. CVE-2016-2184, CVE-2016-2185, CVE-2016-2186, CVE-2016-2187, CVE-2016-3136, CVE-2016-3137, CVE-2016-3138, CVE-2016-3140 Ralf Spenneberg of OpenSource Security reported that various USB drivers do not sufficiently validate USB descriptors. This allowed a physically present user with a specially designed USB device to cause a denial of service (crash). Not all the drivers have yet been fixed. CVE-2016-3134 The Google Project Zero team found that the netfilter subsystem does not sufficiently validate filter table entries. A user with the CAP_NET_ADMIN capability could use this for denial of service (crash) or possibly for privilege escalation. CVE-2016-3157 / XSA-171 Andy Lutomirski discovered that the x86_64 (amd64) task switching implementation did not correctly update the I/O permission level when running as a Xen paravirtual (PV) guest. In some configurations this would allow local users to cause a denial of service (crash) or to escalate their privileges within the guest. CVE-2016-3672 Hector Marco and Ismael Ripoll noted that it was still possible to disable Address Space Layout Randomisation (ASLR) for x86_32 (i386) programs by removing the stack resource limit. This made it easier for local users to exploit security flaws in programs that have the setuid or setgid flag set. CVE-2016-3951 It was discovered that the cdc_ncm driver would free memory prematurely if certain errors occurred during its initialisation. This allowed a physically present user with a specially designed USB device to cause a denial of service (crash) or possibly to escalate their privileges. CVE-2016-3955 Ignat Korchagin reported that the usbip subsystem did not check the length of data received for a USB buffer. This allowed denial of service (crash) or privilege escalation on a system configured as a usbip client, by the usbip server or by an attacker able to impersonate it over the network. A system configured as a usbip server might be similarly vulnerable to physically present users. CVE-2016-3961 / XSA-174 Vitaly Kuznetsov of Red Hat discovered that Linux allowed use of hugetlbfs on x86 (i386 and amd64) systems even when running as a Xen paravirtualised (PV) guest, although Xen does not support huge pages. This allowed users with access to /dev/hugepages to cause a denial of service (crash) in the guest. CVE-2016-4482, CVE-2016-4485, CVE-2016-4486, CVE-2016-4569, CVE-2016-4578, CVE-2016-4580, CVE-2016-5243, CVE-2016-5244 Kangjie Lu reported that the USB devio, llc, rtnetlink, ALSA timer, x25, tipc, and rds facilities leaked information from the kernel stack. CVE-2016-4565 Jann Horn of Google Project Zero reported that various components in the InfiniBand stack implemented unusual semantics for the write() operation. On a system with InfiniBand drivers loaded, local users could use this for denial of service or privilege escalation. CVE-2016-4913 Al Viro found that the ISO9660 filesystem implementation did not correctly count the length of certain invalid name entries. Reading a directory containing such name entries would leak information from kernel memory. Users permitted to mount disks or disk images could use this to obtain sensitive information. For Debian 7 'Wheezy', these problems have been fixed in version 3.2.81-1. This update also fixes bug #627782, which caused data corruption in some applications running on an aufs filesystem, and includes many other bug fixes from upstream stable updates 3.2.79, 3.2.80 and 3.2.81. For Debian 8 'Jessie', these problems will be fixed soon. We recommend that you upgrade your linux packages.

Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
