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."}], "lastModified": "2026-01-22T14:53:48.393", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:rustcrypto:sm2_elliptic_curve:0.14.0:pre0:*:*:*:rust:*:*", "vulnerable": true, "matchCriteriaId": "5F5BCFE9-1585-4A90-857F-7F9E1B9C9ADA"}, {"criteria": "cpe:2.3:a:rustcrypto:sm2_elliptic_curve:0.14.0:rc0:*:*:*:rust:*:*", "vulnerable": true, "matchCriteriaId": "B584C50F-8ED4-45F4-8799-7CCFE8D4DF66"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
