Nethermind Juno Potential Denial of Service (DoS) via Integer Overflow
CVE-2025-29072 · GHSA-wq32-8rp4-w2mc
- Affected
- Go github.com/NethermindEth/juno < 0.12.5
- Fixed in
- 0.12.5· Vendor fix available
- Issue
- An integer overflow in Nethermind Juno before v0.12.5 within the Sierra bytecode decompression logic within the "cairo-lang-starknet-classes" library could allow remote attackers to trigger an infinite loop (and high CPU usage) by submitting a malicious Declare v2/v3 transaction. This results in a denial-of-service condition for affected Starknet full-node implementations.
Recommended action: Upgrade to 0.12.5 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
