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

This updated advisory text mentions the additional non-security changes and notes the need to install new binary packages.

CVE-2019-0136

It was discovered that the wifi soft-MAC implementation (mac80211) did not properly authenticate Tunneled Direct Link Setup (TDLS) messages.
A nearby attacker could use this for denial of service (loss of wifi connectivity).

CVE-2019-9506

Daniele Antonioli, Nils Ole Tippenhauer, and Kasper Rasmussen discovered a weakness in the Bluetooth pairing protocols, dubbed the 'KNOB attack'. An attacker that is nearby during pairing could use this to weaken the encryption used between the paired devices, and then to eavesdrop on and/or spoof communication between them.

This update mitigates the attack by requiring a minimum encryption key length of 56 bits.

CVE-2019-11487

Jann Horn discovered that the FUSE (Filesystem-in-Userspace) facility could be used to cause integer overflow in page reference counts, leading to a use-after-free. On a system with sufficient physical memory, a local user permitted to create arbitrary FUSE mounts could use this for privilege escalation.

By default, unprivileged users can only mount FUSE filesystems through fusermount, which limits the number of mounts created and should completely mitigate the issue.

CVE-2019-15211

The syzkaller tool found a bug in the radio-raremono driver that could lead to a use-after-free. An attacker able to add and remove USB devices could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation.

CVE-2019-15212

The syzkaller tool found that the rio500 driver does not work correctly if more than one device is bound to it. An attacker able to add USB devices could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation.

CVE-2019-15215

The syzkaller tool found a bug in the cpia2_usb driver that leads to a use-after-free. An attacker able to add and remove USB devices could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation.

CVE-2019-15216

The syzkaller tool found a bug in the yurex driver that leads to a use-after-free. An attacker able to add and remove USB devices could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation.

CVE-2019-15218

The syzkaller tool found that the smsusb driver did not validate that USB devices have the expected endpoints, potentially leading to a NULL pointer dereference. An attacker able to add USB devices could use this to cause a denial of service (BUG/oops).

CVE-2019-15219

The syzkaller tool found that a device initialisation error in the sisusbvga driver could lead to a NULL pointer dereference. An attacker able to add USB devices could use this to cause a denial of service (BUG/oops).

CVE-2019-15220

The syzkaller tool found a race condition in the p54usb driver which could lead to a use-after-free. An attacker able to add and remove USB devices could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation.

CVE-2019-15221

The syzkaller tool found that the line6 driver did not validate USB devices' maximum packet sizes, which could lead to a heap buffer overrun. An attacker able to add USB devices could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation.

CVE-2019-15292

The Hulk Robot tool found missing error checks in the Appletalk protocol implementation, which could lead to a use-after-free. The security impact of this is unclear.

CVE-2019-15538

Benjamin Moody reported that operations on XFS hung after a chgrp command failed due to a disk quota. A local user on a system using XFS and disk quotas could use this for denial of service.

CVE-2019-15666

The Hulk Robot tool found an incorrect range check in the network transformation (xfrm) layer, leading to out-of-bounds memory accesses.
A local user with CAP_NET_ADMIN capability (in any user namespace) could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation.

CVE-2019-15807

Jian Luo reported that the Serial Attached SCSI library (libsas) did not correctly handle failure to discover devices beyond a SAS expander. This could lead to a resource leak and crash (BUG). The security impact of this is unclear.

CVE-2019-15924

The Hulk Robot tool found a missing error check in the fm10k Ethernet driver, which could lead to a NULL pointer dereference and crash (BUG/oops). The security impact of this is unclear.

CVE-2019-15926

It was found that the ath6kl wifi driver did not consistently validate traffic class numbers in received control packets, leading to out-of-bounds memory accesses. A nearby attacker on the same wifi network could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation.

For Debian 8 'Jessie', these problems have been fixed in version 4.9.189-3. This version also includes a fix for Debian bug #930904, and other fixes included in upstream stable updates.

We recommend that you upgrade your linux-4.9 and linux-latest-4.9 packages. You will need to use 'apt-get upgrade --with-new-pkgs' or 'apt upgrade' as the binary package names have changed.

The SUSE Linux Enterprise 15 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed :

CVE-2019-15291: There was a NULL pointer dereference, caused by a malicious USB device in the flexcop_usb_probe function in the drivers/media/usb/b2c2/flexcop-usb.c driver (bnc#1146540).

CVE-2019-14821: An out-of-bounds access issue was found in the way the KVM hypervisor implements the Coalesced MMIO write operation. It operates on an MMIO ring buffer 'struct kvm_coalesced_mmio' object, wherein write indices 'ring->first' and 'ring->last' value could be supplied by a host user-space process. An unprivileged host user or process with access to '/dev/kvm' device could use this flaw to crash the host kernel, resulting in a denial of service or potentially escalating privileges on the system (bnc#1151350).

CVE-2017-18595: A double free may be caused by the function allocate_trace_buffer in the file kernel/trace/trace.c (bnc#1149555).

CVE-2019-9506: The Bluetooth BR/EDR specification up to and including version 5.1 permitted sufficiently low encryption key length and did not prevent an attacker from influencing the key length negotiation.
This allowed practical brute-force attacks (aka 'KNOB') that could decrypt traffic and injected arbitrary ciphertext without the victim noticing (bnc#1137865 bnc#1146042).

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

The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has kernel packages installed that are affected by multiple vulnerabilities:

  - An issue was discovered in the Linux kernel before     4.18.7. In block/blk-core.c, there is an
    __blk_drain_queue() use-after-free because a certain     error case is mishandled. (CVE-2018-20856)

  - A flaw was found in the Linux kernel. A heap based     buffer overflow in mwifiex_uap_parse_tail_ies function     in drivers/net/wireless/marvell/mwifiex/ie.c might lead     to memory corruption and possibly other consequences.
    (CVE-2019-10126)

  - A vulnerability was found in Linux kernel's, versions up     to 3.10, implementation of overlayfs. An attacker with     local access can create a denial of service situation     via NULL pointer dereference in ovl_posix_acl_create     function in fs/overlayfs/dir.c. This can allow attackers     with ability to create directories on overlayfs to crash     the kernel creating a denial of service (DOS).
    (CVE-2019-10140)

  - A flaw that allowed an attacker to corrupt memory and     possibly escalate privileges was found in the mwifiex     kernel module while connecting to a malicious wireless     network. (CVE-2019-3846)

  - The Bluetooth BR/EDR specification up to and including     version 5.1 permits sufficiently low encryption key     length and does not prevent an attacker from influencing     the key length negotiation. This allows practical brute-     force attacks (aka KNOB) that can decrypt traffic and     inject arbitrary ciphertext without the victim noticing.
    (CVE-2019-9506)

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

The version of AOS installed on the remote host is prior to 5.11.3. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-5.11.3 advisory.

  - A heap overflow flaw was found in the Linux kernel, all versions 3.x.x and 4.x.x before 4.18.0, in Marvell     WiFi chip driver. The vulnerability allows a remote attacker to cause a system crash, resulting in a     denial of service, or execute arbitrary code. The highest threat with this vulnerability is with the     availability of the system. If code execution occurs, the code will run with the permissions of root. This     will affect both confidentiality and integrity of files on the system. (CVE-2019-14901)

  - OpenSLP as used in ESXi and the Horizon DaaS appliances has a heap overwrite issue. VMware has evaluated     the severity of this issue to be in the Critical severity range with a maximum CVSSv3 base score of 9.8.
    (CVE-2019-5544)

  - In Sudo before 1.8.28, an attacker with access to a Runas ALL sudoer account can bypass certain policy     blacklists and session PAM modules, and can cause incorrect logging, by invoking sudo with a crafted user     ID. For example, this allows bypass of !root configuration, and USER= logging, for a sudo -u     \#$((0xffffffff)) command. (CVE-2019-14287)

  - Empty or malformed p256-ECDH public keys may trigger a segmentation fault due values being improperly     sanitized before being copied into memory and used. This vulnerability affects Firefox ESR < 60.8, Firefox     < 68, and Thunderbird < 60.8. (CVE-2019-11729)

  - When encrypting with a block cipher, if a call to NSC_EncryptUpdate was made with data smaller than the     block size, a small out of bounds write could occur. This could have caused heap corruption and a     potentially exploitable crash. This vulnerability affects Thunderbird < 68.3, Firefox ESR < 68.3, and     Firefox < 71. (CVE-2019-11745)

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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - The Bluetooth BR/EDR specification up to and including version 5.1 permits sufficiently low encryption key     length and does not prevent an attacker from influencing the key length negotiation. This allows practical     brute-force attacks (aka KNOB) that can decrypt traffic and inject arbitrary ciphertext without the     victim noticing. (CVE-2019-9506)

Note that Nessus relies on the presence of the package as reported by the vendor.
