Summary

The HMAC implementation (crypto/hmac.c) in the Linux kernel before 4.14.8 does not validate that the underlying cryptographic hash algorithm is unkeyed, allowing a local attacker able to use the AF_ALG-based hash interface (CONFIG_CRYPTO_USER_API_HASH) and the SHA-3 hash algorithm (CONFIG_CRYPTO_SHA3) to cause a kernel stack buffer overflow by executing a crafted sequence of system calls that encounter a missing SHA-3 initialization.

    "The SUSE Linux Enterprise 12 SP1 LTSS kernel was updated to receive
    various security and bugfixes. The following security bugs were 
    fixed :
    
      - CVE-2017-5715: Systems with microprocessors utilizing
        speculative execution and indirect branch prediction may
        allow unauthorized disclosure of information to an
        attacker with local user access via a side-channel
        analysis (bnc#1068032). The previous fix using CPU
        Microcode has been complemented by building the Linux
        Kernel with return trampolines aka 'retpolines'.
    
      - CVE-2017-18079: drivers/input/serio/i8042.c allowed
        attackers to cause a denial of service (NULL pointer
        dereference and system crash) or possibly have
        unspecified other impact because the port->exists value
        can change after it is validated (bnc#1077922).
    
      - CVE-2015-1142857: Prevent guests from sending ethernet
        flow control pause frames via the PF (bnc#1077355).
    
      - CVE-2017-17741: KVM allowed attackers to obtain
        potentially sensitive information from kernel memory,
        aka a write_mmio stack-based out-of-bounds read
        (bnc#1073311).
    
      - CVE-2017-13215: Prevent elevation of privilege
        (bnc#1075908).
    
      - CVE-2018-1000004: Prevent race condition in the sound
        system, this could have lead a deadlock and denial of
        service condition (bnc#1076017).
    
      - CVE-2017-17806: The HMAC implementation did not validate
        that the underlying cryptographic hash algorithm is
        unkeyed, allowing a local attacker able to use the
        AF_ALG-based hash interface
        (CONFIG_CRYPTO_USER_API_HASH) and the SHA-3 hash
        algorithm (CONFIG_CRYPTO_SHA3) to cause a kernel
        stack-based buffer overflow by executing a crafted
        sequence of system calls that encounter a missing SHA-3
        initialization (bnc#1073874).
    
      - CVE-2017-17805: The Salsa20 encryption algorithm did not
        correctly handle zero-length inputs, allowing a local
        attacker able to use the AF_ALG-based skcipher interface
        (CONFIG_CRYPTO_USER_API_SKCIPHER) to cause a denial of
        service (uninitialized-memory free and kernel crash) or
        have unspecified other impact by executing a crafted
        sequence of system calls that use the blkcipher_walk
        API. Both the generic implementation
        (crypto/salsa20_generic.c) and x86 implementation
        (arch/x86/crypto/salsa20_glue.c) of Salsa20 were
        vulnerable (bnc#1073792).
    
    The update package also includes non-security fixes. See advisory for
    details.

    descriptionThe SUSE Linux Enterprise 11 SP4 kernel was updated to receive various security and bugfixes. This update adds mitigations for various side channel attacks against modern CPUs that could disclose content of otherwise unreadable memory (bnc#1068032). - CVE-2017-5753: Local attackers on systems with modern CPUs featuring deep instruction pipelining could use attacker controllable speculative execution over code patterns in the Linux Kernel to leak content from otherwise not readable memory in the same address space, allowing retrieval of passwords, cryptographic keys and other secrets. This problem is mitigated by adding speculative fencing on affected code paths throughout the Linux kernel. This issue is addressed for the x86_64, the IBM Power and IBM zSeries architecture. - CVE-2017-5715: Local attackers on systems with modern CPUs featuring branch prediction could use mispredicted branches to speculatively execute code patterns that in turn could be made to leak other non-readable content in the same address space, an attack similar to CVE-2017-5753. This problem is mitigated by disabling predictive branches, depending on CPU architecture either by firmware updates and/or fixes in the user-kernel privilege boundaries. This is done with help of Linux Kernel fixes on the Intel/AMD x86_64 and IBM zSeries architectures. On x86_64, this requires also updates of the CPU microcode packages, delivered in separate updates. For IBM Power and zSeries the required firmware updates are supplied over regular channels by IBM. As this feature can have a performance impact, it can be disabled using the

  • NASL familyHuawei Local Security Checks
    NASL idEULEROS_SA-2018-1026.NASL
    descriptionAccording to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities : - The XFRM dump policy implementation in net/xfrm/xfrm_user.c in the Linux kernel before 4.13.11 allows local users to gain privileges or cause a denial of service (use-after-free) via a crafted SO_RCVBUF setsockopt system call in conjunction with XFRM_MSG_GETPOLICY Netlink messages.(CVE-2017-16939) - The bio_map_user_iov and bio_unmap_user functions in block/bio.c in the Linux kernel before 4.13.8 do unbalanced refcounting when a SCSI I/O vector has small consecutive buffers belonging to the same page. The bio_add_pc_page function merges them into one, but the page reference is never dropped. This causes a memory leak and possible system lockup (exploitable against the host OS by a guest OS user, if a SCSI disk is passed through to a virtual machine) due to an out-of-memory condition.(CVE-2017-12190) - The assoc_array_insert_into_terminal_node function in lib/assoc_array.c in the Linux kernel before 4.13.11 mishandles node splitting, which allows local users to cause a denial of service (NULL pointer dereference and panic) via a crafted application, as demonstrated by the keyring key type, and key addition and link creation operations.(CVE-2017-12193) - The ip6_find_1stfragopt function in net/ipv6/output_core.c in the Linux kernel through 4.12.3 allows local users to cause a denial of service (integer overflow and infinite loop) by leveraging the ability to open a raw socket.(CVE-2017-7542) - The bnep_add_connection function in net/bluetooth/bnep/core.c in the Linux kernel before 3.19 does not ensure that an l2cap socket is available, which allows local users to gain privileges via a crafted application.(CVE-2017-15868) - The dccp_disconnect function in net/dccp/proto.c in the Linux kernel through 4.14.3 allows local users to gain privileges or cause a denial of service (use-after-free) via an AF_UNSPEC connect system call during the DCCP_LISTEN state.(CVE-2017-8824) - net/netfilter/nfnetlink_cthelper.c in the Linux kernel through 4.14.4 does not require the CAP_NET_ADMIN capability for new, get, and del operations, which allows local users to bypass intended access restrictions because the nfnl_cthelper_list data structure is shared across all net namespaces.(CVE-2017-17448) - The __netlink_deliver_tap_skb function in net/netlink/af_netlink.c in the Linux kernel through 4.14.4, when CONFIG_NLMON is enabled, does not restrict observations of Netlink messages to a single net namespace, which allows local users to obtain sensitive information by leveraging the CAP_NET_ADMIN capability to sniff an nlmon interface for all Netlink activity on the system.(CVE-2017-17449) - net/netfilter/xt_osf.c in the Linux kernel through 4.14.4 does not require the CAP_NET_ADMIN capability for add_callback and remove_callback operations, which allows local users to bypass intended access restrictions because the xt_osf_fingers data structure is shared across all net namespaces.(CVE-2017-17450) - The usb_destroy_configuration function in drivers/usb/core/config.c in the USB core subsystem in the Linux kernel through 4.14.5 does not consider the maximum number of configurations and interfaces before attempting to release resources, which allows local users to cause a denial of service (out-of-bounds write access) or possibly have unspecified other impact via a crafted USB device.(CVE-2017-17558) - The Salsa20 encryption algorithm in the Linux kernel before 4.14.8 does not correctly handle zero-length inputs, allowing a local attacker able to use the AF_ALG-based skcipher interface (CONFIG_CRYPTO_USER_API_SKCIPHER) to cause a denial of service (uninitialized-memory free and kernel crash) or have unspecified other impact by executing a crafted sequence of system calls that use the blkcipher_walk API. Both the generic implementation (crypto/salsa20_generic.c) and x86 implementation (arch/x86/crypto/salsa20_glue.c) of Salsa20 were vulnerable.(CVE-2017-17805) - The HMAC implementation (crypto/hmac.c) in the Linux kernel before 4.14.8 does not validate that the underlying cryptographic hash algorithm is unkeyed, allowing a local attacker able to use the AF_ALG-based hash interface (CONFIG_CRYPTO_USER_API_HASH) and the SHA-3 hash algorithm (CONFIG_CRYPTO_SHA3) to cause a kernel stack buffer overflow by executing a crafted sequence of system calls that encounter a missing SHA-3 initialization.(CVE-2017-17806) - he KEYS subsystem in the Linux kernel before 4.14.6 omitted an access-control check when adding a key to the current task

    descriptionSeveral vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks. - CVE-2017-8824 Mohamed Ghannam discovered that the DCCP implementation did not correctly manage resources when a socket is disconnected and reconnected, potentially leading to a use-after-free. A local user could use this for denial of service (crash or data corruption) or possibly for privilege escalation. On systems that do not already have the dccp module loaded, this can be mitigated by disabling it:echo >> /etc/modprobe.d/disable-dccp.conf install dccp false - CVE-2017-16538 Andrey Konovalov reported that the dvb-usb-lmedm04 media driver did not correctly handle some error conditions during initialisation. A physically present user with a specially designed USB device can use this to cause a denial of service (crash). - CVE-2017-16644 Andrey Konovalov reported that the hdpvr media driver did not correctly handle some error conditions during initialisation. A physically present user with a specially designed USB device can use this to cause a denial of service (crash). - CVE-2017-16995 Jann Horn discovered that the Extended BPF verifier did not correctly model the behaviour of 32-bit load instructions. A local user can use this for privilege escalation. - CVE-2017-17448 Kevin Cernekee discovered that the netfilter subsystem allowed users with the CAP_NET_ADMIN capability in any user namespace, not just the root namespace, to enable and disable connection tracking helpers. This could lead to denial of service, violation of network security policy, or have other impact. - CVE-2017-17449 Kevin Cernekee discovered that the netlink subsystem allowed users with the CAP_NET_ADMIN capability in any user namespace to monitor netlink traffic in all net namespaces, not just those owned by that user namespace. This could lead to exposure of sensitive information. - CVE-2017-17450 Kevin Cernekee discovered that the xt_osf module allowed users with the CAP_NET_ADMIN capability in any user namespace to modify the global OS fingerprint list. - CVE-2017-17558 Andrey Konovalov reported that that USB core did not correctly handle some error conditions during initialisation. A physically present user with a specially designed USB device can use this to cause a denial of service (crash or memory corruption), or possibly for privilege escalation. - CVE-2017-17712 Mohamed Ghannam discovered a race condition in the IPv4 raw socket implementation. A local user could use this to obtain sensitive information from the kernel. - CVE-2017-17741 Dmitry Vyukov reported that the KVM implementation for x86 would over-read data from memory when emulating an MMIO write if the kvm_mmio tracepoint was enabled. A guest virtual machine might be able to use this to cause a denial of service (crash). - CVE-2017-17805 It was discovered that some implementations of the Salsa20 block cipher did not correctly handle zero-length input. A local user could use this to cause a denial of service (crash) or possibly have other security impact. - CVE-2017-17806 It was discovered that the HMAC implementation could be used with an underlying hash algorithm that requires a key, which was not intended. A local user could use this to cause a denial of service (crash or memory corruption), or possibly for privilege escalation. - CVE-2017-17807 Eric Biggers discovered that the KEYS subsystem lacked a check for write permission when adding keys to a process

On systems that do not already have the dccp module loaded, this can be mitigated by disabling it:echo >> /etc/modprobe.d/disable-dccp.conf install dccp false - CVE-2017-15868 Al Viro found that the Bluebooth Network Encapsulation Protocol (BNEP) implementation did not validate the type of the second socket passed to the BNEPCONNADD ioctl(), which could lead to memory corruption. A local user with the CAP_NET_ADMIN capability can use this for denial of service (crash or data corruption) or possibly for privilege escalation. - CVE-2017-16538 Andrey Konovalov reported that the dvb-usb-lmedm04 media driver did not correctly handle some error conditions during initialisation. A physically present user with a specially designed USB device can use this to cause a denial of service (crash). - CVE-2017-16939 Mohamed Ghannam reported (through Beyond Security
