Name of the Vulnerable Software and Affected Versions nimiq/core-rs-albatross versions prior to 1.3.0

Description An untrusted peer can cause a validator to crash. This occurs when a signed tendermint proposal message is published where the signer is equal to validators.num validators(). The ProposalSender::send() function uses a greater-than operator instead of a greater-than-or-equal-to operator for the signer bounds check. This allows the equality case to proceed to the validators.get validator by slot band(signer) function, which triggers a panic due to an out-of-bounds index before signature verification occurs.

Recommendations Update to version 1.3.0.
