Summary

An integer overflow in Nethermind Juno before v.12.05 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.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
