Incorrect Conversion between Numeric Types in Besu Ethereum Client
Vulnerability Description
Besu is a Java-based Ethereum client. In versions newer than 22.1.3 and prior to 22.7.1, Besu is subject to an Incorrect Conversion between Numeric Types. An error in 32 bit signed and unsigned types in the calculation of available gas in the CALL operations (including DELEGATECALL) results in incorrect gas being passed into called contracts and incorrect gas being returned after call execution. Where the amount of gas makes a difference in the success or failure, or if the gas is a negative 64 bit value, the execution will result in a different state root than expected, resulting in a consensus failure in networks with multiple EVM implementations. In networks with a single EVM implementation this can be used to execute with significantly more gas than then transaction requested, possibly exceeding gas limitations. This issue is patched in version 22.7.1. As a workaround, reverting to version 22.1.3 or earlier will prevent incorrect execution.

Hyperledger Besu 安全漏洞
Vulnerability Description
Hyperledger Besu是 （Hyperledger）开源的一个应用程序。用于运行，维护，调试和监视以太坊网络中的节点。 Hyperledger Besu 22.1.3至22.7.1之前的版本存在安全漏洞，该漏洞源于其在CALL操作（包括DELEGATECALL）中计算可用gas时，32位有符号和无符号类型的错误会导致错误的gas传递到被调用的契约中，并在调用执行后返回错误的gas。如果gas的数量对成功或失败有影响，或者gas为负64位值，则执行将导致与预期不同的状态根，从而在具有多个EVM实现
