Synopsis

The remote Red Hat host is missing one or more security updates for kernel-alt.

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.

The kernel-alt packages provide the Linux kernel version 4.x.

Security Fix(es):

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

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

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

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

* 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: Null pointer dereference in drop_sysctl_table() in fs/proc/proc_sysctl.c (CVE-2019-20054)

* kernel: memory leak in mwifiex_tm_cmd in drivers/net/wireless/marvell/mwifiex/cfg80211.c (CVE-2019-20095)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Bug Fix(es):

* rhel-alt-76z bsd process accounting(acct(2)) does not work (BZ#1763618)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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