CVE-2024-34478

7.5 highEPSS 0.6%

High (7.5) in btcd project btcd. EPSS 0.6% chance of exploitation in the next 30 days. Fixed in github.com/btcsuite/btcd 0.24.0.

btcd before 0.24.0 does not correctly implement the consensus rules outlined in BIP 68 and BIP 112, making it susceptible to consensus failures. Specifically, it uses the transaction version as a signed integer when it is supposed to be treated as unsigned. There can be a chain split and loss of funds.
