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)

- kernel: powerpc: incomplete Spectre-RSB mitigation leads to information exposure (CVE-2019-18660)

- kernel: Heap overflow in mwifiex_update_bss_desc_with_ie function in marvell/mwifiex/scan.c (CVE-2019-3846)

- kernel: af_alg_release() in crypto/af_alg.c neglects to set a NULL value for a certain structure member, which leads to a use-after-free in sockfs_setattr (CVE-2019-8912)

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