Vulnerability Information

Severity: High
Vulnerability Published: 2022-03-16
Patch Published: 2022-04-14
CVE [?]: CVE-2021-39698, CVE-2022-27666
CPE [?]: cpe:/o:novell:suse_linux:15, p-cpe:/a:novell:suse_linux:kernel-livepatch-5_3_18-24_102-default, p-cpe:/a:novell:suse_linux:kernel-livepatch-5_3_18-150300_59_49-default

Synopsis

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

Description

The remote SUSE Linux SLES15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:1224-1 advisory.

- In aio_poll_complete_work of aio.c, there is a possible memory corruption due to a use after free. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-185125206References: Upstream kernel (CVE-2021-39698)

- A heap buffer overflow flaw was found in IPsec ESP transformation code in net/ipv4/esp4.c and net/ipv6/esp6.c. This flaw allows a local attacker with a normal user privilege to overwrite kernel heap objects and may cause a local privilege escalation threat. (CVE-2022-27666)

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

Solution

Update the affected kernel-livepatch-5_3_18-150300_59_49-default and / or kernel-livepatch-5_3_18-24_102-default packages.

How to Run

Here is how to run the SUSE SLES15 Security Update : kernel (Live Patch 14 for SLE 15 SP3) (SUSE-SU-2022:1224-1) as a standalone plugin via the Nessus web user interface (https://localhost:8834/):

Click to start a New Scan.
Select Advanced Scan.
Navigate to the Plugins tab.
On the top right corner click to Disable All plugins.
On the left side table select SuSE Local Security Checks plugin family.
On the right side table select SUSE SLES15 Security Update : kernel (Live Patch 14 for SLE 15 SP3) (SUSE-SU-2022:1224-1) plugin ID 159751.
Specify the target on the Settings tab and click to Save the scan.
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-2022-1224-1.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a suse_SU-2022-1224-1.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-2022-1224-1.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-2022-1224-1.nasl -t <IP/HOST>

Go back to menu.
