Description

MOOS-IvP through 24.8.1 contains multiple buffer overflow vulnerabilities in IvP function string decoders that trust attacker-controlled length fields without validation. Attackers can craft malicious encoded strings with mismatched declared and actual field lengths to overflow heap and stack buffers, potentially achieving remote code execution through MOOS variables or alog files.

Affected products

• moos-ivp: before 24.8.1 — fixed in 24.8.1

How to fix

Upgrade to a fixed version: moos-ivp 24.8.1. Check the vendor advisory for mitigations.
