Synopsis

The remote SUSE host is missing one or more security updates.

Description

The SUSE Linux Enterprise 12 SP2 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed :

CVE-2021-3347: A use-after-free was discovered in the PI futexes during fault handling, allowing local users to execute code in the kernel (bnc#1181349).

CVE-2020-29569: Fixed a potential privilege escalation and information leaks related to the PV block backend, as used by Xen (bnc#1179509).

CVE-2020-29568: Fixed a denial of service issue, related to processing watch events (bnc#1179508).

CVE-2020-25211: Fixed a flaw where a local attacker was able to inject conntrack netlink configuration that could cause a denial of service or trigger the use of incorrect protocol numbers in ctnetlink_parse_tuple_filter (bnc#1176395).

CVE-2020-0444: Fixed a bad kfree due to a logic error in audit_data_to_entry (bnc#1180027).

CVE-2020-0465: Fixed multiple missing bounds checks in hid-multitouch.c that could have led to local privilege escalation (bnc#1180029).

CVE-2020-0466: Fixed a use-after-free due to a logic error in do_epoll_ctl and ep_loop_check_proc of eventpoll.c (bnc#1180031).

CVE-2020-15436: Fixed a use after free vulnerability in fs/block_dev.c which could have allowed local users to gain privileges or cause a denial of service (bsc#1179141).

CVE-2020-27068: Fixed an out-of-bounds read due to a missing bounds check in the nl80211_policy policy of nl80211.c (bnc#1180086).

CVE-2020-27777: Fixed a privilege escalation in the Run-Time Abstraction Services (RTAS) interface, affecting guests running on top of PowerVM or KVM hypervisors (bnc#1179107).

CVE-2020-27786: Fixed an out-of-bounds write in the MIDI implementation (bnc#1179601).

CVE-2020-27825: Fixed a race in the trace_open and buffer resize calls (bsc#1179960).

CVE-2020-29660: Fixed a locking inconsistency in the tty subsystem that may have allowed a read-after-free attack against TIOCGSID (bnc#1179745).

CVE-2020-29661: Fixed a locking issue in the tty subsystem that allowed a use-after-free attack against TIOCSPGRP (bsc#1179745).

CVE-2020-28974: Fixed a slab-out-of-bounds read in fbcon which could have been used by local attackers to read privileged information or potentially crash the kernel (bsc#1178589).

CVE-2020-28915: Fixed a buffer over-read in the fbcon code which could have been used by local attackers to read kernel memory (bsc#1178886).

CVE-2020-25669: Fixed a use-after-free read in sunkbd_reinit() (bsc#1178182).

CVE-2020-25285: A race condition between hugetlb sysctl handlers in mm/hugetlb.c could be used by local attackers to corrupt memory, cause a NULL pointer dereference, or possibly have unspecified other impact (bnc#1176485 ).

CVE-2020-15437: Fixed a NULL pointer dereference which could have allowed local users to cause a denial of service (bsc#1179140).

CVE-2020-36158: Fixed a potential remote code execution in the Marvell mwifiex driver (bsc#1180559).

CVE-2020-11668: Fixed the mishandling of invalid descriptors in the Xirlink camera USB driver (bnc#1168952).

CVE-2020-25668: Fixed a use-after-free in con_font_op() (bsc#1178123).

CVE-2020-27673: Fixed an issue where rogue guests could have caused denial of service of Dom0 via high frequency events (XSA-332 bsc#1177411)

CVE-2019-20934: Fixed a use-after-free in show_numa_stats() because NUMA fault statistics were inappropriately freed (bsc#1179663).

CVE-2019-19063: Fixed two memory leaks in the rtl_usb_probe() which could eventually have allowed attackers to cause a denial of service (memory consumption) (bnc#1157298 ).

CVE-2019-6133: Fixed an issue where the 'start time' protection mechanism could have been bypassed and therefore authorization decisions are improperly cached (bsc#1128172).

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

How to Run

Here is how to run the SUSE SLES12 Security Update : kernel (SUSE-SU-2021:0437-1) as a standalone plugin via the Nessus web user interface (https://localhost:8834/):

  1. Click to start a New Scan.
  2. Select Advanced Scan.
  3. Navigate to the Plugins tab.
  4. On the top right corner click to Disable All plugins.
  5. On the left side table select SuSE Local Security Checks plugin family.
  6. On the right side table select SUSE SLES12 Security Update : kernel (SUSE-SU-2021:0437-1) plugin ID 146476.
  7. Specify the target on the Settings tab and click to Save the scan.
  8. Run the scan.

Here are a few examples of how to run the plugin in the command line. Note that the examples below demonstrate the usage on the Linux / Unix platform.

Basic usage:

/opt/nessus/bin/nasl suse_SU-2021-0437-1.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a suse_SU-2021-0437-1.nasl -t <IP/HOST>

Run the plugin with trace script execution written to the console (useful for debugging):

/opt/nessus/bin/nasl -T - suse_SU-2021-0437-1.nasl -t <IP/HOST>

Run the plugin with using a state file for the target and updating it (useful for running multiple plugins on the target):

/opt/nessus/bin/nasl -K /tmp/state suse_SU-2021-0437-1.nasl -t <IP/HOST>

Go back to menu.
