Denial of Service (DoS) Affecting sqlite3 package, versions >=1.5.0, <1.5.1

Affected versions of this package are vulnerable to Denial of Service (DoS) via the FTS3 extension, due to 32-bit signed integer overflow. In order to exploit this vulnerability, the attacker must have full SQL access and must be able to construct a corrupt database with over 2GB of FTS3 content.

Users who are unable to upgrade the sqlite3 gem can compile and link sqlite3 against external libsqlite >= 3.39.4, which will also address these same issues.

Denial of Service (DoS) describes a family of attacks, all aimed at making a system inaccessible to its intended and legitimate users.

Unlike other vulnerabilities, DoS attacks usually do not aim at breaching security. Rather, they are focused on making websites and services unavailable to genuine users resulting in downtime.

One popular Denial of Service vulnerability is DDoS (a Distributed Denial of Service), an attack that attempts to clog network pipes to the system by generating a large volume of traffic from many machines.

When it comes to open source libraries, DoS vulnerabilities allow attackers to trigger such a crash or crippling of the service by using a flaw either in the application code or from the use of open source libraries.

Two common types of DoS vulnerabilities:

• High CPU/Memory Consumption- An attacker sending crafted requests that could cause the system to take a disproportionate amount of time to process. For example, commons-fileupload:commons-fileupload.

• Crash - An attacker sending crafted requests that could cause the system to crash. For Example, npm ws package

• GitHub Commit
• GitHub Release
