Overview

Veilid before version 0.1.9 contains a critical vulnerability (CVE-2023-40711) that was discovered and disclosed in August 2023. The vulnerability affects the data decompression functionality when receiving envelopes, as the software fails to properly validate the size of uncompressed data (NVD).

Technical details

The vulnerability has been assigned a CVSS v3.1 base score of 7.5 (HIGH) with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H. The technical issue stems from the lack of size validation during the decompression of data when processing envelope receipts. This vulnerability is classified as CWE-787 (Out-of-bounds Write) (NVD).

Impact

When exploited, this vulnerability can lead to a denial of service condition through an out-of-memory abort. This occurs when an attacker sends specially crafted packet data to the system, causing it to consume excessive memory resources during the decompression process (NVD).

Mitigation and workarounds

The vulnerability has been fixed in Veilid version 0.1.9. Users and administrators are strongly advised to upgrade to this version or later to protect against potential attacks (Veilid Changelog).
