CVE-2025-29072
CVSS v3.1
7.5
High
| Vector | AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
Nethermind Juno versions prior to 0.12.5
Description
The issue is caused by an integer overflow within the Sierra bytecode decompression logic in the "cairo-lang-starknet-classes" library. This allows remote attackers to trigger an infinite loop and high CPU usage by submitting a malicious Declare v2/v3 transaction, resulting in a denial-of-service condition for affected Starknet full-node implementations.
Recommendations
For versions prior to 0.12.5, update to version 0.12.5 or later to resolve the issue. As a temporary workaround, consider restricting access to the "cairo-lang-starknet-classes" library to minimize the risk of exploitation. Avoid processing malicious Declare v2/v3 transactions until the issue is resolved.
Fix
Integer Overflow
Allocation of Resources Without Limits
