CVE-2025-29072
Nethermind Juno Potential Denial of Service (DoS) via Integer Overflow
Impact
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.
