Vulnerability Title
RustCrypto Cmov/CmovEq on aarch64 can produce wrong results if high-bits of registers are set
Vulnerability Description
RustCrypto CMOV provides conditional move CPU intrinsics which are guaranteed on major platforms to execute in constant-time and not be rewritten as branches by the compiler. From 0.1.1 until 0.5.4, the aarch64 implementations of Cmov and CmovEq in cmov/src/backends/aarch64.rs assume high bits are zero-extended when loading values smaller than a register, so set high bits such as [8..] in a Cmov selector or [16..] of self or other in the u16 and i16 CmovEq implementations can cause left.cmovz(&right, condition) to produce incorrect output. This issue is fixed in version 0.5.4.

Vulnerability Title
RustCrypto cmov 处理逻辑错误漏洞
Vulnerability Description
RustCrypto cmov是RustCrypto团队开源的一个Rust密码学库组件。 RustCrypto cmov 0.1.1版本至0.5.4之前版本存在处理逻辑错误漏洞,该漏洞源于aarch64架构中Cmov和CmovEq实现假设高位在加载小于寄存器大小的值时被零扩展,导致设置高比特位时可能产生错误输出。
