high Nessus Plugin ID 158337

Language:

Synopsis

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

Description

The remote SUSE Linux SLES12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:0555-1 advisory.

- The vgacon subsystem in the Linux kernel before 5.8.10 mishandles software scrollback. There is a vgacon_scrolldelta out-of-bounds read, aka CID-973c096f6a85. (CVE-2020-28097)

- A flaw double-free memory corruption in the Linux kernel HCI device initialization subsystem was found in the way user attach malicious HCI TTY Bluetooth device. A local user could use this flaw to crash the system. This flaw affects all the Linux kernel versions starting from 3.13. (CVE-2021-3564)

- In gadget_dev_desc_UDC_show of configfs.c, there is a possible disclosure of kernel heap memory due to a race condition. This could lead to local information disclosure with System execution privileges needed.
User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID:
A-160822094References: Upstream kernel (CVE-2021-39648)

- In ufshcd_eh_device_reset_handler of ufshcd.c, there is a possible out of bounds read due to a missing bounds check. This could lead to local information disclosure with System execution privileges needed.

A-194696049References: Upstream kernel (CVE-2021-39657)

- A read-after-free memory flaw was found in the Linux kernel's garbage collection for Unix domain socket file handlers in the way users call close() and fget() simultaneously and can potentially trigger a race condition. This flaw allows a local user to crash the system or escalate their privileges on the system.
This flaw affects Linux kernel versions prior to 5.16-rc4. (CVE-2021-4083)

- A denial of service flaw for virtual machine guests in the Linux kernel's Xen hypervisor subsystem was found in the way users call some interrupts with high frequency from one of the guests.A local user could use this flaw to starve the resources resulting in a denial of service. (CVE-2021-28711) (CVE-2021-4135)

- A use-after-free exists in drivers/tee/tee_shm.c in the TEE subsystem in the Linux kernel through 5.15.11.
This occurs because of a race condition in tee_shm_get_from_id during an attempt to free a shared memory object. (CVE-2021-44733)

- pep_sock_accept in net/phonet/pep.c in the Linux kernel through 5.15.8 has a refcount leak.
(CVE-2021-45095)

- kernel: possible privileges escalation due to missing TLB flush (CVE-2022-0330)

- kernel: failing usercopy allows for use-after-free exploitation (CVE-2022-22942)

- An issue was discovered in fs/nfs/dir.c in the Linux kernel before 5.16.5. If an application sets the O_DIRECTORY flag, and tries to open a regular file, nfs_atomic_open() performs a regular lookup. If a regular file is found, ENOTDIR should occur, but the server instead returns uninitialized data in the file descriptor. (CVE-2022-24448)

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

Solution

Update the affected packages.
