Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:0174 advisory.

- kernel: Use-after-free due to race condition in AF_PACKET implementation (CVE-2018-18559)

- Kernel: speculative bounds check bypass store (CVE-2018-3693)

- kernel: Heap overflow in mwifiex_uap_parse_tail_ies function in drivers/net/wireless/marvell/mwifiex/ie.c (CVE-2019-10126)

- kernel: Count overflow in FUSE request leading to use-after-free issues. (CVE-2019-11487)

- kernel: heap overflow in mwifiex_set_uap_rates() function of Marvell Wifi Driver leading to DoS (CVE-2019-14814)

- kernel: heap-overflow in mwifiex_set_wmm_params() function of Marvell WiFi driver leading to DoS (CVE-2019-14815)

- kernel: heap overflow in mwifiex_update_vs_ie() function of Marvell WiFi driver (CVE-2019-14816)

- kernel: buffer overflow in cfg80211_mgd_wext_giwessid in net/wireless/wext-sme.c (CVE-2019-17133)
