Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:1493 advisory.

- kernel: heap-based buffer overflow in mwifiex_process_country_ie() function in drivers/net/wireless/marvell/mwifiex/sta_ioctl.c (CVE-2019-14895)

- kernel: heap overflow in marvell/mwifiex/tdls.c (CVE-2019-14901)

- kernel: powerpc: local user can read vector registers of other users' processes via an interrupt (CVE-2019-15031)

- kernel: a NULL pointer dereference in drivers/net/wireless/ath/ath10k/usb.c leads to a crash (CVE-2019-15099)

- kernel: out-of-bounds array access in
__xfrm_policy_unlink (CVE-2019-15666)

- kernel: when cpu.cfs_quota_us is used allows attackers to cause a denial of service against non-cpu-bound applications (CVE-2019-19922)

- kernel: triggering AP to send IAPP location updates for stations before the required authentication process has completed can lead to DoS (CVE-2019-5108)

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.
