Linux Kernel CVE-2019-17133 Buffer Overflow Vulnerability

Description

Linux Kernel is prone to a buffer-overflow vulnerability. Attackers can exploit this issue to execute arbitrary code on the affected application. Failed attempts will likely cause a denial-of-service condition. Linux kernel versions through 5.3.2 are vulnerable.

Recommendations

Block external access at the network boundary, unless external parties require service.
Filter access to the affected computer at the network boundary if global access isn’t needed. Restricting access to only trusted computers and networks might greatly reduce the likelihood of a successful exploit.

Run all software as a nonprivileged user with minimal access rights.
To limit the potential damage that successful exploits may achieve, run all nonadministrative software as an unprivileged user.

Deploy network intrusion detection systems to monitor network traffic for malicious activity.
Deploy NIDS to monitor network traffic for signs of anomalous or suspicious activity. This may indicate exploit attempts or activity that results from successful exploits.

Implement multiple redundant layers of security.
Various memory-protection schemes (such as nonexecutable and randomly mapped memory segments) may hinder an attacker’s ability to exploit this vulnerability to execute arbitrary code.

Updates are available. Please see the references or vendor advisory for more information.
