The SUSE Linux Enterprise 15 kernel was updated to receive various security and bugfixes. The following security bugs were fixed :

  - CVE-2018-15572: The spectre_v2_select_mitigation     function in arch/x86/kernel/cpu/bugs.c did not always     fill RSB upon a context switch, which made it easier for     attackers to conduct userspace-userspace spectreRSB     attacks (bnc#1102517 bnc#1105296).

  - CVE-2018-10902: It was found that the raw midi kernel     driver did 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 (bnc#1105322).

  - CVE-2018-9363: A buffer overflow in bluetooth HID report     processing could be used by malicious bluetooth devices     to crash the kernel or potentially execute code     (bnc#1105292).

  - CVE-2018-10853: A KVM guest userspace to guest kernel     write was fixed, which could be used by guest users to     crash the guest kernel (bnc#1097104).

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

This update for the Linux Kernel 3.12.61-52_133 fixes several issues.
The following security issues were fixed :

  - CVE-2018-3646: Local attackers in virtualized guest     systems could use speculative code patterns on     hyperthreaded processors to read data present in the L1     Datacache used by other hyperthreads on the same CPU     core, potentially leaking sensitive data, even from     other virtual machines or the host system (bsc#1099306).

  - CVE-2018-10853: A flaw was found in kvm. In which     certain instructions such as sgdt/sidt call     segmented_write_std didn't propagate access correctly.
    As such, during userspace induced exception, the guest     can incorrectly assume that the exception happened in     the kernel and panic. (bsc#1097108).

  - CVE-2017-11600: net/xfrm/xfrm_policy.c did not ensure     that the dir value of xfrm_userpolicy_id is     XFRM_POLICY_MAX or less, which allowed local users to     cause a denial of service (out-of-bounds access) or     possibly have unspecified other impact via an     XFRM_MSG_MIGRATE xfrm Netlink message (bsc#1096564)

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.
