CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:N/AC:M/Au:S/C:P/I:P/A:C

Summary:
The remote host is missing an update for the 'bpftool' Linux Distribution Package(s) announced via the CESA-2020:5437 advisory.

Detection Method:
Checks if a vulnerable Linux Distribution Package version is present on the target host.

Technical Details:
The kernel Linux Distribution Packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es): * kernel: metadata validator in XFS may cause an inode with a valid, user-creatable extended attribute to be flagged as corrupt (CVE-2020-14385) * kernel: The flow_dissector feature allows device tracking (CVE-2019-18282) * kernel: Buffer over-read in crypto_authenc_extractkeys() when a payload longer than 4 bytes is not aligned. (CVE-2020-10769) * kernel: buffer uses out of index in ext3/4 filesystem (CVE-2020-14314) * kernel: umask not applied on filesystem without ACL support (CVE-2020-24394) * kernel: TOCTOU mismatch in the NFS client code (CVE-2020-25212) * kernel: improper input validation in ppp_cp_parse_cr function leads to memory corruption and read overflow (CVE-2020-25643) 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): * WARNING in set_restore_sigmask at ./arch/x86/include/asm/thread_info.h:298 sigsuspend+0x6d/0x70 (BZ#1704650) * [i40e] VFs see other VF's outgoing traffic (BZ#1845677) * [Hyper-V][RHEL7] Two fixes for kdump over network (BZ#1846667) * Loop in __run_timers() because base->timer_jiffies is very far behind causes a lockup condition. (BZ#1849716) * XFS transaction overrun when running docker on VMWARE (overlay fs) (BZ#1857203) * RHEL 7.9 NVMe/IB - Host crash encountered during array upgrade (BZ#1857397) * False positive hard lockup detected while disabling the hard lockup detector via sysctl -w kernel.watchdog=0 (BZ#1860661) * [Hyper-V][RHEL-7] Only notify Hyper-V for die events that are oops (BZ#1868130) * Linux kernel crash due to openvswitch module (BZ#1869190) * 'nodfs' option not working when using SMB2+ (BZ#1873033) * RHEL7.7 zstream - ESS - kernel panic triggered by freelist pointer corruption (BZ#1873189) * destroy_cfs_bandwidth() is called by free_fair_sched_group() without calling init_cfs_bandwidth() (BZ#1878000) * NULL pointer at nvme_rdma_setup_ctrl+0x1c2/0x8d0 [nvme_rdma] when discover E5700 (BZ#1878950) * IB Infiniband RDMA mlx5_ib is freeing a kmalloc-512 cache that it does not own causing memory corruption. (BZ#1880184) * [Azure][RHEL7] Two Patches Needed To Enable Azure Host Time-syncing in VMs (BZ#1884735) * connect AF_UNSPEC on a connecting AF_INET6 socket returns an error (BZ#1886305) * Rebuilding the grub with the CPU flag 'avx' disabled (clearcpuid=156) triggers kernel panic in xor_avx_2() (BZ#1886792) * nf_conntrack_sctp.h is not usable due to a missing commit (BZ#1887975) * Starting pvmove on top of physical volumes on MD devices causes IO error on ongoing IO (BZ#1890059)

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
