SQLite CVE-2019-8457 Out of Bounds Read Heap Buffer Overflow Vulnerability



Date Discovered

October 16, 2019


SQLite is prone to a remote heap-based buffer-overflow vulnerability. Attackers can exploit this issue to crash the application, resulting in a denial-of-service condition. Due to the nature of this issue, arbitrary code execution may be possible but this has not been confirmed.

Run all software as a nonprivileged user with minimal access rights.
To reduce the impact of latent vulnerabilities, always run nonadministrative software as an unprivileged user with minimal access rights.

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 includes but is not limited to requests that include NOP sleds and unexplained incoming and outgoing traffic. This may indicate exploit attempts or activity that results from successful exploits.

Do not accept or execute files from untrusted or unknown sources.
To reduce the likelihood of successful exploits, do not open files that originate from untrusted sources.

Do not follow links provided by unknown or untrusted sources.
To reduce the likelihood of successful exploits, never visit sites of questionable integrity or follow links provided by unfamiliar or untrusted sources.

Implement multiple redundant layers of security.
Memory-protection schemes (such as nonexecutable stack and heap configurations and randomly mapped memory segments) will complicate exploits of memory-corruption vulnerabilities.

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