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.

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.

The SUSE Linux Enterprise 11 SP3 kernel was updated to receive various security and bugfixes.

NOTE: the scope of CVE-2015-0272 is     limited to the NetworkManager product (bnc#955354).

  - CVE-2015-8539: The KEYS subsystem in the Linux kernel     allowed local users to gain privileges or cause a denial     of service (BUG) via crafted keyctl commands that     negatively instantiate a key, related to     security/keys/encrypted-keys/encrypted.c,     security/keys/trusted.c, and     security/keys/user_defined.c (bnc#958463).

  - CVE-2015-8543: The networking implementation in the     Linux kernel did not validate protocol identifiers for     certain protocol families, which allowed local users to     cause a denial of service (NULL function pointer     dereference and system crash) or possibly gain     privileges by leveraging CLONE_NEWUSER support to     execute a crafted SOCK_RAW application (bnc#958886).

  - CVE-2015-8550: Optimizations introduced by the compiler     could have lead to double fetch vulnerabilities,     potentially possibly leading to arbitrary code execution     in backend (bsc#957988). (bsc#957988 XSA-155).

  - CVE-2015-8551: The PCI backend driver in Xen, when     running on an x86 system and using Linux as the driver     domain, allowed local guest administrators to hit BUG     conditions and cause a denial of service (NULL pointer     dereference and host OS crash) by leveraging a system     with access to a passed-through MSI or MSI-X capable     physical PCI device and a crafted sequence of     XEN_PCI_OP_* operations, aka 'Linux pciback missing     sanity checks (bnc#957990).

  - CVE-2015-8552: The PCI backend driver in Xen, when     running on an x86 system and using Linux as the driver     domain, allowed local guest administrators to generate a     continuous stream of WARN messages and cause a denial of     service (disk consumption) by leveraging a system with     access to a passed-through MSI or MSI-X capable physical     PCI device and XEN_PCI_OP_enable_msi operations, aka     'Linux pciback missing sanity checks (bnc#957990).

  - CVE-2015-8569: The (1) pptp_bind and (2) pptp_connect     functions in drivers/net/ppp/pptp.c in the Linux kernel     do not verify an address length, which allowed local     users to obtain sensitive information from kernel memory     and bypass the KASLR protection mechanism via a crafted     application (bnc#959190).

  - CVE-2015-8575: The sco_sock_bind function in     net/bluetooth/sco.c in the Linux kernel did not verify     an address length, which allowed local users to obtain     sensitive information from kernel memory and bypass the     KASLR protection mechanism via a crafted application     (bnc#959399).

  - CVE-2015-8767: net/sctp/sm_sideeffect.c in the Linux     kernel did not properly manage the relationship between     a lock and a socket, which allowed local users to cause     a denial of service (deadlock) via a crafted sctp_accept     call (bnc#961509).

  - CVE-2015-8785: The fuse_fill_write_pages function in     fs/fuse/file.c in the Linux kernel allowed local users     to cause a denial of service (infinite loop) via a     writev system call that triggers a zero length for the     first segment of an iov (bnc#963765).

  - CVE-2015-8812: A flaw was found in the CXGB3 kernel     driver when the network was considered congested. The     kernel would incorrectly misinterpret the congestion as     an error condition and incorrectly free/clean up the     skb. When the device would then send the skb's queued,     these structures would be referenced and may panic the     system or allow an attacker to escalate privileges in a     use-after-free scenario.(bsc#966437).

According to the versions of the kernel packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - A use-after-free flaw was found in the way the Linux     kernel's key management subsystem handled keyring     object reference counting in certain error path of the     join_session_keyring() function. A local, unprivileged     user could use this flaw to escalate their privileges     on the system.(CVE-2016-0728)

  - A flaw was found in the way the Linux kernel's ASN.1     DER decoder processed certain certificate files with     tags of indefinite length. A local, unprivileged user     could use a specially crafted X.509 certificate DER     file to crash the system or, potentially, escalate     their privileges on the system.(CVE-2016-0758)

  - The LIST_POISON feature in include/linux/poison.h in     the Linux kernel before 4.3, as used in Android 6.0.1     before 2016-03-01, does not properly consider the     relationship to the mmap_min_addr value, which makes it     easier for attackers to bypass a poison-pointer     protection mechanism by triggering the use of an     uninitialized list entry, aka Android internal bug     26186802, a different vulnerability than     CVE-2015-3636.(CVE-2016-0821)

  - The pagemap_open function in fs/proc/task_mmu.c in the     Linux kernel before 3.19.3, as used in Android 6.0.1     before 2016-03-01, allows local users to obtain     sensitive physical-address information by reading a     pagemap file, aka Android internal bug     25739721.(CVE-2016-0823)

  - The aio_mount function in fs/aio.c in the Linux kernel     does not properly restrict execute access, which makes     it easier for local users to bypass intended SELinux     W^X policy restrictions.(CVE-2016-10044)

  - It was found that the fix for CVE-2016-9576 was     incomplete: the Linux kernel's sg implementation did     not properly restrict write operations in situations     where the KERNEL_DS option is set. A local attacker to     read or write to arbitrary kernel memory locations or     cause a denial of service (use-after-free) by     leveraging write access to a /dev/sg     device.(CVE-2016-10088)

  - A use-after-free flaw was found in the Linux kernel     which enables a race condition in the L2TPv3 IP     Encapsulation feature. A local user could use this flaw     to escalate their privileges or crash the     system.(CVE-2016-10200)

  - Mounting a crafted EXT4 image read-only leads to an     attacker controlled memory corruption and     SLAB-Out-of-Bounds reads.(CVE-2016-10208)

  - The Linux kernel allows remote attackers to execute     arbitrary code via UDP traffic that triggers an unsafe     second checksum calculation during execution of a recv     system call with the MSG_PEEK flag. This may create a     kernel panic or memory corruption leading to privilege     escalation.(CVE-2016-10229)

  - The overlayfs implementation in the Linux kernel     through 4.5.2 does not properly maintain POSIX ACL     xattr data, which allows local users to gain privileges     by leveraging a group-writable setgid     directory.(CVE-2016-1575)

  - The overlayfs implementation in the Linux kernel     through 4.5.2 does not properly restrict the mount     namespace, which allows local users to gain privileges     by mounting an overlayfs filesystem on top of a FUSE     filesystem, and then executing a crafted setuid     program.(CVE-2016-1576)

  - A syntax vulnerability was discovered in the kernel's     ASN1.1 DER decoder, which could lead to memory     corruption or a complete local denial of service     through x509 certificate DER files. A local system user     could use a specially created key file to trigger     BUG_ON() in the public_key_verify_signature() function     (crypto/asymmetric_keys/public_key.c), to cause a     kernel panic and crash the system.(CVE-2016-2053)

  - A flaw was discovered in the way the Linux kernel dealt     with paging structures. When the kernel invalidated a     paging structure that was not in use locally, it could,     in principle, race against another CPU that is     switching to a process that uses the paging structure     in question. A local user could use a thread running     with a stale cached virtual-i1/4zphysical translation to     potentially escalate their privileges if the     translation in question were writable and the physical     page got reused for something critical (for example, a     page table).(CVE-2016-2069)

  - A divide-by-zero vulnerability was found in a way the     kernel processes TCP connections. The error can occur     if a connection starts another cwnd reduction phase by     setting tp-i1/4zprior_cwnd to the current cwnd (0) in     tcp_init_cwnd_reduction(). A remote, unauthenticated     attacker could use this flaw to crash the kernel     (denial of service).(CVE-2016-2070)

  - It was discovered that the atl2_probe() function in the     Atheros L2 Ethernet driver in the Linux kernel     incorrectly enabled scatter/gather I/O. A remote     attacker could use this flaw to obtain potentially     sensitive information from the kernel     memory.(CVE-2016-2117)

  - The create_fixed_stream_quirk function in     sound/usb/quirks.c in the snd-usb-audio driver in the     Linux kernel before 4.5.1 allows physically proximate     attackers to cause a denial of service (NULL pointer     dereference or double free, and system crash) via a     crafted endpoints value in a USB device     descriptor.(CVE-2016-2184)

  - The ati_remote2_probe function in     drivers/input/misc/ati_remote2.c in the Linux kernel     before 4.5.1 allows 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.(CVE-2016-2185)

  - The powermate_probe function in     drivers/input/misc/powermate.c in the Linux kernel     before 4.5.1 allows 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.(CVE-2016-2186)

  - The gtco_probe function in drivers/input/tablet/gtco.c     in the Linux kernel through 4.5.2 allows 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.(CVE-2016-2187)

  - The iowarrior_probe function in     drivers/usb/misc/iowarrior.c in the Linux kernel before     4.5.1 allows 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.(CVE-2016-2188)

  - A flaw was found in the USB-MIDI Linux kernel driver: a     double-free error could be triggered for the 'umidi'     object. An attacker with physical access to the system     could use this flaw to escalate their     privileges.(CVE-2016-2384)

  - The snd_seq_ioctl_remove_events function in     sound/core/seq/seq_clientmgr.c in the Linux kernel     before 4.4.1 does not verify FIFO assignment before     proceeding with FIFO clearing, which allows local users     to cause a denial of service (NULL pointer dereference     and OOPS) via a crafted ioctl call.(CVE-2016-2543)

  - Race condition in the queue_delete function in     sound/core/seq/seq_queue.c in the Linux kernel before     4.4.1 allows local users to cause a denial of service     (use-after-free and system crash) by making an ioctl     call at a certain time.(CVE-2016-2544)
