Vulnerability Title
RustCrypto Has Insufficient Length Validation in decrypt() in SM2-PKE
Vulnerability Description
RustCrypto: Elliptic Curves is general purpose Elliptic Curve Cryptography (ECC) support, including types and traits for representing various elliptic curve forms, scalars, points, and public/secret keys composed thereof. In versions 0.14.0-pre.0 and 0.14.0-rc.0, a denial-of-service vulnerability exists in the SM2 public-key encryption (PKE) implementation: the decrypt() path performs unchecked slice::split_at operations on input buffers derived from untrusted ciphertext. An attacker can submit short/undersized ciphertext or carefully-crafted DER-encoded structures to trigger bounds-check panics (Rust unwinding) which crash the calling thread or process. This issue has been patched via commit e60e991.

Vulnerability Type
输入验证不恰当
Vulnerability Title
RustCrypto: Elliptic Curves 输入验证错误漏洞
Vulnerability Description
RustCrypto: Elliptic Curves是Rust Crypto开源的一个Rust加密库。 RustCrypto: Elliptic Curves 0.14.0-pre.0版本和0.14.0-rc.0版本存在输入验证错误漏洞，该漏洞源于SM2公钥加密实现中对源自不受信任密文的输入缓冲区执行未检查的切片分割操作，可能导致拒绝服务攻击。
