The remote SUSE Linux SLES11 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2020:14354-1 advisory.

  - ** DISPUTED ** An issue was discovered in the MPT3COMMAND case in _ctl_ioctl_main in     drivers/scsi/mpt3sas/mpt3sas_ctl.c in the Linux kernel through 5.1.5. It allows local users to cause a     denial of service or possibly have unspecified other impact by changing the value of ioc_number between     two kernel reads of that value, aka a double fetch vulnerability. NOTE: a third party reports that this     is unexploitable because the doubly fetched value is not used. (CVE-2019-12456)

  - A heap-based buffer overflow vulnerability was found in the Linux kernel, version kernel-2.6.32, in     Marvell WiFi chip driver. A remote attacker could cause a denial of service (system crash) or, possibly     execute arbitrary code, when the lbs_ibss_join_existing function is called after a STA connects to an AP.
    (CVE-2019-14896)

  - A stack-based buffer overflow was found in the Linux kernel, version kernel-2.6.32, in Marvell WiFi chip     driver. An attacker is able to cause a denial of service (system crash) or, possibly execute arbitrary     code, when a STA works in IBSS mode (allows connecting stations together without the use of an AP) and     connects to another STA. (CVE-2019-14897)

    CVE-2020-0305     In cdev_get of char_dev.c, there is a possible use-after-free due to a race condition. This could lead to     local escalation of privilege with System execution privileges needed. User interaction is not needed for     exploitation.Product: AndroidVersions: Android-10Android ID: A-153467744     CVE-2020-10732     A flaw was found in the Linux kernel's implementation of Userspace core dumps. This flaw allows an     attacker with a local account to crash a trivial program and exfiltrate private kernel data.
    CVE-2020-10751     A flaw was found in the Linux kernels SELinux LSM hook implementation before version 5.7, where it     incorrectly assumed that an skb would only contain a single netlink message. The hook would incorrectly     only validate the first netlink message in the skb and allow or deny the rest of the messages within the     skb with the granted permission without further processing.
    CVE-2020-10773     A stack information leak flaw was found in s390/s390x in the Linux kernels memory manager functionality,     where it incorrectly writes to the /proc/sys/vm/cmm_timeout file. This flaw allows a local user to see the     kernel data.

    CVE-2020-10942     In the Linux kernel before 5.5.8, get_raw_socket in drivers/vhost/net.c lacks validation of an sk_family     field, which might allow attackers to trigger kernel stack corruption via crafted system calls.
    CVE-2020-11565
    ** DISPUTED ** An issue was discovered in the Linux kernel through 5.6.2. mpol_parse_str in mm/mempolicy.c     has a stack-based out-of-bounds write because an empty nodelist is mishandled during mount option parsing,     aka CID-aa9f7d5172fa. NOTE: Someone in the security community disagrees that this is a vulnerability     because the issue is a bug in parsing mount options which can only be specified by a privileged user, so     triggering the bug does not grant any powers not already held..
    CVE-2020-11668     In the Linux kernel before 5.6.1, drivers/media/usb/gspca/xirlink_cit.c (aka the Xirlink camera USB     driver) mishandles invalid descriptors, aka CID-a246b4d54770.
    CVE-2020-12465     An array overflow was discovered in mt76_add_fragment in drivers/net/wireless/mediatek/mt76/dma.c in the     Linux kernel before 5.5.10, aka CID-b102f0c522cf. An oversized packet with too many rx fragments can     corrupt memory of adjacent pages.
    CVE-2020-12655     An issue was discovered in xfs_agf_verify in fs/xfs/libxfs/xfs_alloc.c in the Linux kernel through 5.6.10.

    CVE-2020-12659     An issue was discovered in the Linux kernel before 5.6.7. xdp_umem_reg in net/xdp/xdp_umem.c has an out-     of-bounds write (by a user with the CAP_NET_ADMIN capability) because of a lack of headroom validation.
    CVE-2020-12770     An issue was discovered in the Linux kernel through 5.6.11. sg_write lacks an sg_remove_request call in a     certain failure case, aka CID-83c6f2390040.
    CVE-2020-12826     A signal access-control issue was discovered in the Linux kernel before 5.6.5, aka CID-7395ea4e65c2.
    Because exec_id in include/linux/sched.h is only 32 bits, an integer overflow can interfere with a     do_notify_parent protection mechanism. A child process can send an arbitrary signal to a parent process in     a different security domain. Exploitation limitations include the amount of elapsed time before an integer     overflow occurs, and the lack of scenarios where signals to a parent process present a substantial     operational threat.

    CVE-2020-8649     There is a use-after-free vulnerability in the Linux kernel through 5.5.2 in the vgacon_invert_region     function in drivers/video/console/vgacon.c.

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

Note that Nessus has not tested for these issues 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 5.19.1. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-5.19.1 advisory.

  - In Network Security Services (NSS) before 3.46, several cryptographic primitives had missing length     checks. In cases where the application calling the library did not perform a sanity check on the inputs it     could result in a crash due to a buffer overflow. (CVE-2019-17006)

  - Heap buffer overflow in the TFTP protocol handler in cURL 7.19.4 to 7.65.3. (CVE-2019-5482)

  - In all versions of cpio before 2.13 does not properly validate input files when generating TAR archives.
    When cpio is used to create TAR archives from paths an attacker can write to, the resulting archive may     contain files with permissions the attacker did not have or in paths he did not have access to. Extracting     those archives from a high-privilege user without carefully reviewing them may lead to the compromise of     the system. (CVE-2019-14866)

  - If an HTTP/2 client connecting to Apache Tomcat 10.0.0-M1 to 10.0.0-M7, 9.0.0.M1 to 9.0.37 or 8.5.0 to     8.5.57 exceeded the agreed maximum number of concurrent streams for a connection (in violation of the     HTTP/2 protocol), it was possible that a subsequent request made on that connection could contain HTTP     headers - including HTTP/2 pseudo headers - from a previous request rather than the intended headers. This     could lead to users seeing responses for unexpected resources. (CVE-2020-13943)

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Optimizer). Supported     versions that are affected are 5.6.45 and prior, 5.7.27 and prior and 8.0.17 and prior. Easily exploitable     vulnerability allows low privileged attacker with network access via multiple protocols to compromise     MySQL Server. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang     or frequently repeatable crash (complete DOS) of MySQL Server. (CVE-2019-2974)
