For more information on this set of information leaks, check out https://www.suse.com/support/kb/doc/?id=7023736

The following security bugs were fixed: CVE-2018-1128: It was found that cephx authentication protocol did not verify ceph clients correctly and was vulnerable to replay attack. Any attacker having access to ceph cluster network who is able to sniff packets on network could use this vulnerability to authenticate with ceph service and perform actions allowed by ceph service. (bnc#1096748).

CVE-2018-1129: A flaw was found in the way signature calculation was handled by cephx authentication protocol. An attacker having access to ceph cluster network who is able to alter the message payload was able to bypass signature checks done by cephx protocol. (bnc#1096748).

CVE-2016-8636: Integer overflow in the mem_check_range function in drivers/infiniband/sw/rxe/rxe_mr.c allowed local users to cause a denial of service (memory corruption), obtain sensitive information or possibly have unspecified other impact via a write or read request involving the 'RDMA protocol over infiniband' (aka Soft RoCE) technology (bnc#1024908).

CVE-2017-18174: In the amd_gpio_remove function in drivers/pinctrl/pinctrl-amd.c calls the pinctrl_unregister function, leading to a double free (bnc#1080533).

CVE-2018-1091: In the flush_tmregs_to_thread function in arch/powerpc/kernel/ptrace.c, a guest kernel crash can be triggered from unprivileged userspace during a core dump on a POWER host due to a missing processor feature check and an erroneous use of transactional memory (TM) instructions in the core dump path, leading to a denial of service (bnc#1087231).

CVE-2018-1120: By mmap()ing a FUSE-backed file onto a process's memory containing command line arguments (or environment strings), an attacker can cause utilities from psutils or procps (such as ps, w) or any other program which made a read() call to the /proc/<pid>/cmdline (or /proc/<pid>/environ) files to block indefinitely (denial of service) or for some controlled time (as a synchronization primitive for other attacks) (bnc#1093158). </pid></pid>

CVE-2019-11486: The Siemens R3964 line discipline driver in drivers/tty/n_r3964.c has multiple race conditions (bnc#1133188).

CVE-2019-3882: A flaw was found in the vfio interface implementation that permits violation of the user's locked memory limit. If a device is bound to a vfio driver, such as vfio-pci, and the local attacker is administratively granted ownership of the device, it may cause a system memory exhaustion and thus a denial of service (DoS) (bsc#1131427).

CVE-2018-19407: The vcpu_scan_ioapic function in arch/x86/kvm/x86.c allowed local users to cause a denial of service (NULL pointer dereference and BUG) via crafted system calls that reach a situation where ioapic is uninitialized (bnc#1116841).

Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks.

CVE-2017-18249

A race condition was discovered in the disk space allocator of F2FS. A user with access to an F2FS volume could use this to cause a denial of service or other security impact.

CVE-2018-1128, CVE-2018-1129

The cephx authentication protocol used by Ceph was susceptible to replay attacks, and calculated signatures incorrectly. These vulnerabilities in the server required changes to authentication that are incompatible with existing clients. The kernel's client code has now been updated to be compatible with the fixed server.

CVE-2018-3639 (SSB)

Multiple researchers have discovered that Speculative Store Bypass (SSB), a feature implemented in many processors, could be used to read sensitive information from another context. In particular, code in a software sandbox may be able to read sensitive information from outside the sandbox. This issue is also known as Spectre variant 4.

This update adds a further mitigation for this issue in the eBPF (Extended Berkeley Packet Filter) implementation.

CVE-2018-5391 (FragmentSmack)

Juha-Matti Tilli discovered a flaw in the way the Linux kernel handled reassembly of fragmented IPv4 and IPv6 packets. A remote attacker can take advantage of this flaw to trigger time and calculation expensive fragment reassembly algorithms by sending specially crafted packets, leading to remote denial of service.

This was previously mitigated by reducing the default limits on memory usage for incomplete fragmented packets. This update replaces that mitigation with a more complete fix.

CVE-2018-5848

The wil6210 wifi driver did not properly validate lengths in scan and connection requests, leading to a possible buffer overflow. On systems using this driver, a local user with the CAP_NET_ADMIN capability could use this for denial of service (memory corruption or crash) or potentially for privilege escalation.

CVE-2018-12896, CVE-2018-13053

Team OWL337 reported possible integer overflows in the POSIX timer implementation. These might have some security impact.

CVE-2018-13096, CVE-2018-13097, CVE-2018-13100, CVE-2018-14614, CVE-2018-14616

Wen Xu from SSLab at Gatech reported that crafted F2FS volumes could trigger a crash (BUG, Oops, or division by zero) and/or out-of-bounds memory access. An attacker able to mount such a volume could use this to cause a denial of service or possibly for privilege escalation.

CVE-2018-13406

Dr Silvio Cesare of InfoSect reported a potential integer overflow in the uvesafb driver. A user with permission to access such a device might be able to use this for denial of service or privilege escalation.

CVE-2018-14610, CVE-2018-14611, CVE-2018-14612, CVE-2018-14613

Wen Xu from SSLab at Gatech reported that crafted Btrfs volumes could trigger a crash (Oops) and/or out-of-bounds memory access. An attacker able to mount such a volume could use this to cause a denial of service or possibly for privilege escalation.

CVE-2018-15471 ((XSA-270)

Felix Wilhelm of Google Project Zero discovered a flaw in the hash handling of the xen-netback Linux kernel module. A malicious or buggy frontend may cause the (usually privileged) backend to make out of bounds memory accesses, potentially resulting in privilege escalation, denial of service, or information leaks.

https://xenbits.xen.org/xsa/advisory-270.html

CVE-2018-16862

Vasily Averin and Pavel Tikhomirov from Virtuozzo Kernel Team discovered that the cleancache memory management feature did not invalidate cached data for deleted files. On Xen guests using the tmem driver, local users could potentially read data from other users' deleted files if they were able to create new files on the same volume.

CVE-2018-17972

Jann Horn reported that the /proc/*/stack files in procfs leaked sensitive data from the kernel. These files are now only readable by users with the CAP_SYS_ADMIN capability (usually only root)

CVE-2018-18281

Jann Horn reported a race condition in the virtual memory manager that can result in a process briefly having access to memory after it is freed and reallocated. A local user could possibly exploit this for denial of service (memory corruption) or for privilege escalation.

CVE-2018-18690

Kanda Motohiro reported that XFS did not correctly handle some xattr (extended attribute) writes that require changing the disk format of the xattr. A user with access to an XFS volume could use this for denial of service.

CVE-2018-18710

It was discovered that the cdrom driver does not correctly validate the parameter to the CDROM_SELECT_DISC ioctl. A user with access to a cdrom device could use this to read sensitive information from the kernel or to cause a denial of service (crash).

CVE-2018-19407

Wei Wu reported a potential crash (Oops) in the KVM implementation for x86 processors. A user with access to /dev/kvm could use this for denial of service.

For Debian 8 'Jessie', these problems have been fixed in version 4.9.144-3.1~deb8u1. This version also includes fixes for Debian bugs #890034, #896911, #907581, #915229, and #915231; and other fixes included in upstream stable updates.

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

The SUSE Linux Enterprise 15 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-2018-14613: Prevent invalid pointer dereference in io_ctl_map_page() when mounting and operating a crafted btrfs image, caused by a lack of block group item validation in check_leaf_item (bsc#1102896).

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-2018-13093: 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-2018-13094: Prevent OOPS that may have occured for a corrupted xfs image after xfs_da_shrink_inode() is called with a NULL bp (bnc#1100000)

CVE-2018-13095: Prevent denial of service (memory corruption and BUG) that could have occurred for a corrupted xfs image upon encountering an inode that is in extent format, but has more extents than fit in the inode fork (bnc#1099999)

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-2018-16658: 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-2018-10938: A crafted network packet sent remotely by an attacker forced the kernel to enter an infinite loop in the cipso_v4_optptr() function leading to a denial-of-service (bnc#1106016)

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

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.

Multiple vulnerabilities were discovered in Ceph, a distributed storage and file system: The cephx authentication protocol was suspectible to replay attacks and calculated signatures incorrectly, 'ceph mon' did not validate capabilities for pool operations (resulting in potential corruption or deletion of snapshot images) and a format string vulnerability in libradosstriper could result in denial of service.

The SUSE Linux Enterprise 12 SP3 azure kernel was updated to 4.4.155 to receive various security and bugfixes.

The following security bugs were fixed :

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-2018-13095: Prevent denial of service (memory corruption and BUG) that could have occurred for a corrupted xfs image upon encountering an inode that is in extent format, but has more extents than fit in the inode fork (bnc#1099999)

CVE-2018-13094: Prevent OOPS that may have occured for a corrupted xfs image after xfs_da_shrink_inode() is called with a NULL bp (bnc#1100000)

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

CVE-2018-10940: 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-2018-6555: 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-2018-1129: A flaw was found in the way signature calculation was handled by cephx authentication protocol. An attacker having access to ceph cluster network who is able to alter the message payload was able to bypass signature checks done by cephx protocol (bnc#1096748)

CVE-2018-1128: It was found that cephx authentication protocol did not verify ceph clients correctly and was vulnerable to replay attack. Any attacker having access to ceph cluster network who is able to sniff packets on network can use this vulnerability to authenticate with ceph service and perform actions allowed by ceph service (bnc#1096748)

CVE-2018-10938: A crafted network packet sent remotely by an attacker forced the kernel to enter an infinite loop in the cipso_v4_optptr() function leading to a denial-of-service (bnc#1106016)

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).

CVE-2018-9363: Prevent buffer overflow in hidp_process_report (bsc#1105292)

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-2018-10879: 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-2018-10878: 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-2018-10876: A use-after-free was possible in ext4_ext_remove_space() function when mounting and operating a crafted ext4 image (bsc#1099811)

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

CVE-2018-10881: 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-2018-10882: 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-2018-10880: 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)

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2018:2261 advisory.

    Red Hat Ceph Storage is a scalable, open, software-defined storage platform     that combines the most stable version of the Ceph storage system with a     Ceph management platform, deployment utilities, and support services.

    Security Fix(es):

    * ceph: cephx protocol is vulnerable to replay attack (CVE-2018-1128)

    * ceph: cephx uses weak signatures (CVE-2018-1129)

    * ceph: ceph-mon does not perform authorization on OSD pool ops (CVE-2018-10861)

    For more details about the security issue(s), including the impact, a CVSS     score and other related information refer to the CVE page(s) listed in the Reference section.

    Enhancement(s):

    * Ceph OSDs now logs when they shutdown due to disk operations timing out by default. (BZ#1568897)

    * The `radosgw-admin orphans find` command can inadvertently remove data objects still in use, if followed     by another operation, such as, a `rados rm` command. Users are now warned before attempting to produce     lists of potentially orphaned objects. (BZ#1573656)

    * The 'ceph-osdomap-tool' now has a 'compact' command to perform offline compaction on an OSD's 'omap'     directory. (BZ#1574231)

    * For S3 and Swift protocols, an option to list buckets/containers in natural (partial) order has been     added. Listing containers in sorted order is canonical in both protocols, but is costly, and not required     by some client applications. The performance and workload cost of S3 and Swift bucket/container listings     is reduced for sharded buckets/containers when the `allow_unordered` extension is used. (BZ#1595374)

    * An asynchronous mechanism for executing the Ceph Object Gateway garbage collection using the `librados`     APIs has been introduced. The original garbage collection mechanism serialized all processing, and lagged     behind applications in specific workloads. Garbage collection performance has been significantly improved,     and can be tuned to specific site requirements. (BZ#1595383)

    Bug Fix(es):

    These updated ceph packages include numerous bug fixes. Space precludes     documenting all of these changes in this advisory. Users are directed to the Red Hat Ceph Storage 2.5     Release Notes for information on the most significant bug fixes for this release:

    Bug Fix(es):

    * Previously, Ceph RADOS Gateway (RGW) instances in zones configured for multi-site replication would     crash if configured to disable sync (rgw_run_sync_thread = false). Therefor, multi-site replication     environments could not start dedicated non-replication RGW instances. With this update, the     rgw_run_sync_thread option can be used to configure RGW instances that will not participate in     replication even if their zone is replicated. (BZ#1552202)

    * Previously, when increasing max_mds from 1 to 2, if the Metadata Server (MDS) daemon was in the     starting/resolve state for a long period of time, then restarting the MDS daemon lead to assert. This     caused the Ceph File System (CephFS) to be in degraded state. With this update, increasing max_mds no     longer causes CephFS to be in degraded state. (BZ#1566016)

    * Previously, the transition to containerized Ceph left some ceph-disk unit files. The files were     harmless, but appeared as failing. With this update, executing the switch-from-non-containerized-to-     containerized-ceph-daemons.yml playbook disables the ceph-disk unit files too. (BZ#1577846)

    * Previously, the entries_behind_master metric output from the rbd mirror image status CLI tool did     not always reduce to zero under synthetic workloads. This could cause a false alarm that there is an issue     with RBD mirroring replications. With this update, the metric is now updated periodically without the need     for an explicit I/O flush in the workload. (BZ#1578509)

    * Previously, when using the pool create command with expected_num_objects, placement group (PG)     directories were not pre-created at pool creation time as expected, resulting in performance drops when     filestore splitting occurred. With this update, the expected_num_objects parameter is now passed through     to filestore correctly, and PG directories for the expected number of objects are pre-created at pool     creation time. (BZ#1579039)

    * Previously, internal RADOS Gateway (RGW) multi-site sync logic behaved incorrectly when attempting to     sync containers with S3 object versioning enabled. Objects in versioning-enabled containers would fail to     sync in some scenariosfor example, when using s3cmd sync to mirror a filesystem directory. With this     update, RGW multi-site replication logic has been corrected for the known failure cases. (BZ#1580497)

    * When restarting OSD daemons, the ceph-ansible restart script goes through all the daemons by listing     the units with systemctl list-units. Under certain circumstances, the output of the command contains extra     spaces, which caused parsing and restart to fail. With this update, the underlying code has been changed     to handle the extra space.

    * Previously, the Ceph RADOS Gateway (RGW) server treated negative byte-range object requests (bytes=0--     1) as invalid. Applications that expect the AWS behavior for negative or other invalid range requests saw     unexpected errors and could fail. With this update, a new option rgw_ignore_get_invalid_range has been     added to RGW. When rgw_ignore_get_invalid_range is set to true, the RGW behavior for invalid range     requests is backwards compatible with AWS.
