Security Fix(es) :

  - kernel: MIDI driver race condition leads to a     double-free (CVE-2018-10902)

Bug Fix(es) :

  - Previously backported upstream patch caused a change in     the behavior of page fault handler. As a consequence,     applications compiled through GNU Compiler Collection     (GCC) version 4.4.7 sometimes generated stack access     exceeding the 64K limit. Running such applications     subsequently triggered a segmentation fault. With this     update, the 64k limit check in the page fault handler     has been removed. As a result, running the affected     applications no longer triggers the segmentation fault     in the described scenario.

Note that removing the limit check does not impact the integrity of the kernel itself.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote NewStart CGSL host, running version MAIN 4.06, has kernel packages installed that are affected by multiple vulnerabilities:

  - A vulnerability was found in the     fs/inode.c:inode_init_owner() function logic of the     LInux kernel that allows local users to create files     with an unintended group ownership and with group     execution and SGID permission bits set, in a scenario     where a directory is SGID and belongs to a certain group     and is writable by a user who is not a member of this     group. This can lead to excessive permissions granted in     case when they should not. (CVE-2018-13405)

  - It was found that the raw midi kernel driver does not     protect against concurrent access which leads to a     double realloc (double free) in     snd_rawmidi_input_params() and     snd_rawmidi_output_status() which are part of     snd_rawmidi_ioctl() handler in rawmidi.c file. A     malicious local attacker could possibly use this for     privilege escalation. (CVE-2018-10902)

  - Modern Intel microprocessors implement hardware-level     micro-optimizations to improve the performance of     writing data back to CPU caches. The write operation is     split into STA (STore Address) and STD (STore Data) sub-     operations. These sub-operations allow the processor to     hand-off address generation logic into these sub-     operations for optimized writes. Both of these sub-     operations write to a shared distributed processor     structure called the 'processor store buffer'. As a     result, an unprivileged attacker could use this flaw to     read private data resident within the CPU's processor     store buffer. (CVE-2018-12126)

  - A flaw was found in the implementation of the fill     buffer, a mechanism used by modern CPUs when a cache-     miss is made on L1 CPU cache. If an attacker can     generate a load operation that would create a page     fault, the execution will continue speculatively with     incorrect data from the fill buffer while the data is     fetched from higher level caches. This response time can     be measured to infer data in the fill buffer.
    (CVE-2018-12130)

  - Uncacheable memory on some microprocessors utilizing     speculative execution may allow an authenticated user to     potentially enable information disclosure via a side     channel with local access. (CVE-2019-11091)

  - Microprocessors use a load port subcomponent to     perform load operations from memory or IO. During a load     operation, the load port receives data from the memory     or IO subsystem and then provides the data to the CPU     registers and operations in the CPUs pipelines. Stale     load operations results are stored in the 'load port'     table until overwritten by newer operations. Certain     load-port operations triggered by an attacker can be     used to reveal data about previous stale requests     leaking data back to the attacker via a timing side-     channel. (CVE-2018-12127)

The SUSE Linux Enterprise 11 SP4 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed :

CVE-2018-14617: Prevent NULL pointer dereference and panic in hfsplus_lookup() when opening a file (that is purportedly a hard link) in an hfs+ filesystem that has malformed catalog data, and is mounted read-only without a metadata directory (bsc#1102870).

CVE-2018-16276: Incorrect bounds checking in the yurex USB driver in yurex_read allowed local attackers to use user access read/writes to crash the kernel or potentially escalate privileges (bsc#1106095).

CVE-2018-15594: Ensure correct handling of indirect calls, to prevent attackers for conducting Spectre-v2 attacks against paravirtual guests (bsc#1105348).

CVE-2018-14634: Prevent integer overflow in create_elf_tables that allowed a local attacker to exploit this vulnerability via a SUID-root binary and obtain full root privileges (bsc#1108912)

CVE-2018-12896: Prevent integer overflow in the POSIX timer code that was caused by the way the overrun accounting works. Depending on interval and expiry time values, the overrun can be larger than INT_MAX, but the accounting is int based. This basically made the accounting values, which are visible to user space via timer_getoverrun(2) and siginfo::si_overrun, random. This allowed a local user to cause a denial of service (signed integer overflow) via crafted mmap, futex, timer_create, and timer_settime system calls (bnc#1099922)

CVE-2018-10940: The cdrom_ioctl_media_changed function allowed local attackers to use a incorrect bounds check in the CDROM driver CDROM_MEDIA_CHANGED ioctl to read out kernel memory (bsc#1092903)

CVE-2018-16658: Prevent information leak in cdrom_ioctl_drive_status that could have been used by local attackers to read kernel memory (bnc#1107689)

CVE-2018-6555: The irda_setsockopt function allowed local users to cause a denial of service (ias_object use-after-free and system crash) or possibly have unspecified other impact via an AF_IRDA socket (bnc#1106511)

CVE-2018-6554: Prevent memory leak in the irda_bind function that allowed local users to cause a denial of service (memory consumption) by repeatedly binding an AF_IRDA socket (bnc#1106509)

CVE-2018-15572: The spectre_v2_select_mitigation function did not always fill RSB upon a context switch, which made it easier for attackers to conduct userspace-userspace spectreRSB attacks (bnc#1102517)

CVE-2018-10902: Protect against concurrent access to prevent double realloc (double free) in snd_rawmidi_input_params() and snd_rawmidi_output_status(). A malicious local attacker could have used this for privilege escalation (bnc#1105322)

The SUSE Linux Enterprise 12 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed :

CVE-2018-14634: Prevent integer overflow in create_elf_tables that allowed a local attacker to exploit this vulnerability via a SUID-root binary and obtain full root privileges (bsc#1108912)

CVE-2018-14617: Prevent NULL pointer dereference and panic in hfsplus_lookup() when opening a file (that is purportedly a hard link) in an hfs+ filesystem that has malformed catalog data, and is mounted read-only without a metadata directory (bsc#1102870)

CVE-2018-16276: Incorrect bounds checking in the yurex USB driver in yurex_read allowed local attackers to use user access read/writes to crash the kernel or potentially escalate privileges (bsc#1106095)

CVE-2018-12896: Prevent integer overflow in the POSIX timer code that was caused by the way the overrun accounting works. Depending on interval and expiry time values, the overrun can be larger than INT_MAX, but the accounting is int based. This basically made the accounting values, which are visible to user space via timer_getoverrun(2) and siginfo::si_overrun, random. This allowed a local user to cause a denial of service (signed integer overflow) via crafted mmap, futex, timer_create, and timer_settime system calls (bnc#1099922)

CVE-2018-13093: Prevent NULL pointer dereference and panic in lookup_slow() on a NULL inode->i_ops pointer when doing pathwalks on a corrupted xfs image. This occured because of a lack of proper validation that cached inodes are free during allocation (bnc#1100001)

CVE-2018-10940: The cdrom_ioctl_media_changed function allowed local attackers to use a incorrect bounds check in the CDROM driver CDROM_MEDIA_CHANGED ioctl to read out kernel memory (bsc#1092903)

CVE-2018-16658: Prevent information leak in cdrom_ioctl_drive_status that could have been used by local attackers to read kernel memory (bnc#1107689)

CVE-2018-6555: The irda_setsockopt function allowed local users to cause a denial of service (ias_object use-after-free and system crash) or possibly have unspecified other impact via an AF_IRDA socket (bnc#1106511)

CVE-2018-6554: Prevent memory leak in the irda_bind function that allowed local users to cause a denial of service (memory consumption) by repeatedly binding an AF_IRDA socket (bnc#1106509)

CVE-2018-10853: The KVM hypervisor did not check current privilege(CPL) level while emulating unprivileged instructions. An unprivileged guest user/process could have used this flaw to potentially escalate privileges inside guest (bsc#1097104)

CVE-2018-10902: Protect against concurrent access to prevent double realloc (double free) in snd_rawmidi_input_params() and snd_rawmidi_output_status(). A malicious local attacker could have used this for privilege escalation (bnc#1105322).

CVE-2018-10879: A local user could have caused a use-after-free in ext4_xattr_set_entry function and a denial of service or unspecified other impact by renaming a file in a crafted ext4 filesystem image (bsc#1099844)

CVE-2018-10883: A local user could have caused an out-of-bounds write in jbd2_journal_dirty_metadata(), a denial of service, and a system crash by mounting and operating on a crafted ext4 filesystem image (bsc#1099863)

CVE-2018-10880: Prevent stack-out-of-bounds write in the ext4 filesystem code when mounting and writing to a crafted ext4 image in ext4_update_inline_data(). An attacker could have used this to cause a system crash and a denial of service (bsc#1099845)

CVE-2018-10882: A local user could have caused an out-of-bound write, a denial of service, and a system crash by unmounting a crafted ext4 filesystem image (bsc#1099849)

CVE-2018-10881: A local user could have caused an out-of-bound access in ext4_get_group_info function, a denial of service, and a system crash by mounting and operating on a crafted ext4 filesystem image (bsc#1099864)

CVE-2018-10877: Prevent out-of-bound access in the ext4_ext_drop_refs() function when operating on a crafted ext4 filesystem image (bsc#1099846)

CVE-2018-10876: A use-after-free was possible in ext4_ext_remove_space() function when mounting and operating a crafted ext4 image (bsc#1099811)

CVE-2018-10878: A local user could have caused an out-of-bounds write and a denial of service or unspecified other impact by mounting and operating a crafted ext4 filesystem image (bsc#1099813)

CVE-2018-17182: An issue was discovered in the Linux kernel The vmacache_flush_all function in mm/vmacache.c mishandled sequence number overflows. An attacker can trigger a use-after-free (and possibly gain privileges) via certain thread creation, map, unmap, invalidation, and dereference operations (bnc#1108399).

The update package also includes non-security fixes. See advisory for details.

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2018:3096 advisory.

    The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with     extremely high determinism requirements.

    Security Fix(es):

    * A flaw named FragmentSmack was found in the way the Linux kernel handled reassembly of fragmented IPv4     and IPv6 packets. A remote attacker could use this flaw to trigger time and calculation expensive fragment     reassembly algorithm by sending specially crafted packets which could lead to a CPU saturation and hence a     denial of service on the system. (CVE-2018-5391)

    * kernel: out-of-bounds access in the show_timer function in kernel/time/posix-timers.c (CVE-2017-18344)
