CyberRota Analysis
AI-GeneratedThe re2 library for Node.js versions prior to 1.25.2 is vulnerable due to improper handling of the `lastIndex` property, which can lead to an out-of-bounds heap read and potentially crash the process when processing non-ASCII inputs. This vulnerability may expose limited heap information and poses a risk to applications relying on this library for regular expression operations. Developers and organizations using re2 in their Node.js applications should prioritize upgrading to version 1.25.2 or later to mitigate this risk.

Original NVD Description
re2 provides Node.js bindings for Google's RE2 regular expression engine. Prior to 1.25.2, re2 validates lastIndex against the UTF-8 byte length of a subject but uses it as a UTF-16 code-unit offset in exec, test, match, replace, and split, allowing an attacker-influenced lastIndex on a non-ASCII subject to trigger an out-of-bounds heap read and an uncatchable process crash, with limited heap information disclosure in some cases. This issue is fixed in 1.25.2.
