Name of the Vulnerable Software and Affected Versions RustCrypto versions 0.14.0-pre.0 through 0.14.0-rc.0

Description The RustCrypto Elliptic Curves library provides general purpose Elliptic Curve Cryptography (ECC) support. A denial-of-service issue exists in the SM2 PKE decryption path where an invalid elliptic-curve point (C1) is decoded and the resulting value is unwrapped without validation. Specifically, AffinePoint::from encoded point(&encoded c1) may return a None value when the supplied coordinates are syntactically valid but do not lie on the SM2 curve, leading to a panic due to the use of .unwrap().

Recommendations Update to a version past 0.14.0-rc.0.
