Description
MOOS-IvP through version 24.8.1 contains a denial of service vulnerability in the Demuxer::addMuxPacket() function. The vulnerability arises because the function trusts the packet count declared in mux headers without validating it. An attacker can exploit this by declaring an arbitrarily large packet count, causing unbounded memory allocation that exhausts system resources and results in service unavailability.

Technical Analysis
The vulnerability in MOOS-IvP (up to version 24.8.1) is a denial of service issue located in the Demuxer::addMuxPacket() function. This function improperly trusts the packet count declared in mux headers without performing validation. By crafting packets with excessively large declared counts, an attacker can trigger unbounded memory allocation, leading to resource exhaustion and denial of service conditions.
Potential Impact
Successful exploitation leads to denial of service by exhausting system memory resources due to unbounded allocation triggered by maliciously crafted mux packets. There is no impact on confidentiality or integrity reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch links are currently provided. Until a patch is available, consider applying input validation or rate limiting on mux packets if feasible to mitigate exploitation risk.
