Synopsis
The remote EulerOS host is missing multiple security updates.
Description
According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :
- An issue was discovered in the Linux kernel through 5.2.13. nbd_genl_status in drivers/block/nbd.c does not check the nla_nest_start_noflag return value. (CVE-2019-16089)
- A flaw in the processing of received ICMP errors (ICMP fragment needed and ICMP redirect) in the Linux kernel functionality was found to allow the ability to quickly scan open UDP ports. This flaw allows an off-path remote user to effectively bypass the source port UDP randomization. The highest threat from this vulnerability is to confidentiality and possibly integrity, because software that relies on UDP source port randomization are indirectly affected as well. (CVE-2021-20322)
- A use-after-free flaw was found in the Linux kernel's Bluetooth subsystem in the way user calls connect to the socket and disconnect simultaneously due to a race condition. This flaw allows a user to crash the system or escalate their privileges. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. (CVE-2021-3752)
- arch/mips/net/bpf_jit.c in the Linux kernel before 5.4.10 can generate undesirable machine code when transforming unprivileged cBPF programs, allowing execution of arbitrary code within the kernel context. This occurs because conditional branches can exceed the 128 KB limit of the MIPS architecture. (CVE-2021-38300)
- prealloc_elems_and_freelist in kernel/bpf/stackmap.c in the Linux kernel before 5.14.12 allows unprivileged users to trigger an eBPF multiplication integer overflow with a resultant out-of-bounds write. (CVE-2021-41864)
- The firewire subsystem in the Linux kernel through 5.14.13 has a buffer overflow related to drivers/media/firewire/firedtv-avc.c and drivers/media/firewire/firedtv-ci.c, because avc_ca_pmt mishandles bounds checking. (CVE-2021-42739)
Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
Solution
Update the affected kernel packages.
Public Exploits

How to Run
Here is how to run the EulerOS 2.0 SP10 : kernel (EulerOS-SA-2022-1208) 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 Huawei Local Security Checks plugin family.
- On the right side table select EulerOS 2.0 SP10 : kernel (EulerOS-SA-2022-1208) plugin ID 158396.
- 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 EulerOS_SA-2022-1208.nasl -t <IP/HOST>
Run the plugin with audit trail message on the console:
/opt/nessus/bin/nasl -a EulerOS_SA-2022-1208.nasl -t <IP/HOST>
Run the plugin with trace script execution written to the console (useful for debugging):
/opt/nessus/bin/nasl -T - EulerOS_SA-2022-1208.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 EulerOS_SA-2022-1208.nasl -t <IP/HOST>
Go back to menu.
