Synopsis

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

Description

The remote CentOS Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the CESA-2021:1578 advisory.

- kernel: memory leak in sof_set_get_large_ctrl_data() function in sound/soc/sof/ipc.c (CVE-2019-18811)

- kernel: use-after-free caused by a malicious USB device in the drivers/usb/misc/adutux.c driver (CVE-2019-19523)

- kernel: use-after-free bug caused by a malicious USB device in the drivers/usb/misc/iowarrior.c driver (CVE-2019-19528)

- kernel: possible out of bounds write in kbd_keycode of keyboard.c (CVE-2020-0431)

- kernel: NULL pointer dereferences in ov511_mode_init_regs and ov518_mode_init_regs in drivers/media/usb/gspca/ov519.c (CVE-2020-11608)

- kernel: DoS by corrupting mountpoint reference counter (CVE-2020-12114)

- kernel: Integer overflow in Intel(R) Graphics Drivers (CVE-2020-12362)

- kernel: use-after-free in usb_sg_cancel function in drivers/usb/core/message.c (CVE-2020-12464)

- kernel: buffer uses out of index in ext3/4 filesystem (CVE-2020-14314)

- kernel: Use After Free vulnerability in cgroup BPF component (CVE-2020-14356)

- kernel: NULL pointer dereference in serial8250_isa_init_ports function in drivers/tty/serial/8250/8250_core.c (CVE-2020-15437)

- kernel: umask not applied on filesystem without ACL support (CVE-2020-24394)

- kernel: TOCTOU mismatch in the NFS client code (CVE-2020-25212)

- kernel: incomplete permission checking for access to rbd devices (CVE-2020-25284)

- kernel: race condition between hugetlb sysctl handlers in mm/hugetlb.c (CVE-2020-25285)

- kernel: improper input validation in ppp_cp_parse_cr function leads to memory corruption and read overflow (CVE-2020-25643)

- kernel: perf_event_parse_addr_filter memory (CVE-2020-25704)

- kernel: use-after-free in kernel midi subsystem (CVE-2020-27786)

- kernel: child process is able to access parent mm through hfi dev file handle (CVE-2020-27835)

- kernel: slab-out-of-bounds read in fbcon (CVE-2020-28974)

- kernel: fork: fix copy_process(CLONE_PARENT) race with the exiting ->real_parent (CVE-2020-35508)

- kernel: fuse: fuse_do_getattr() calls make_bad_inode() in inappropriate situations (CVE-2020-36322)

- kernel: use after free in tun_get_user of tun.c could lead to local escalation of privilege (CVE-2021-0342)

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.

  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 centos8_RHSA-2021-1578.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a centos8_RHSA-2021-1578.nasl -t <IP/HOST>

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

/opt/nessus/bin/nasl -T - centos8_RHSA-2021-1578.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 centos8_RHSA-2021-1578.nasl -t <IP/HOST>

Go back to menu.
