NixOS vulnerability analysis and mitigation
Overview
An issue was discovered in GoBGP before version 3.35.0. The vulnerability exists in pkg/packet/rtr/rtr.go where the software does not verify that the input length corresponds to a situation in which all bytes are available for an RTR message (NVD, GitHub Commit).
Technical details
The vulnerability is classified as an Off-by-one Error (CWE-193). The CVSS v3.1 base score is 6.8 (MEDIUM) with the vector string CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:N/I:N/A:H. The issue stems from insufficient validation of input length in the RTR message handling component (NVD).
Impact
The vulnerability could lead to a situation where the application attempts to process RTR messages without having all required bytes available, potentially resulting in application crashes or other undefined behavior (NVD).
Mitigation and workarounds
Users should upgrade to GoBGP version 3.35.0 or later which contains the fix for this vulnerability. The fix has been implemented in commit 5693c58a4815cc6327b8d3b6980f0e5aced28abe (GitHub Commit, GitHub Compare).
