| Package | Affected versions | Patched versions |
|---|---|---|
| jsrsasign | < 11.1.1 | 11.1.1 |
| jsrsasign | < 11.1.1 | 11.1.1 |
Versions of the package jsrsasign before 11.1.1 are vulnerable to Division by zero due to the RSASetPublic/KEYUTIL parsing path in ext/rsa.js and the BigInteger.modPowInt reduction logic in ext/jsbn.js. An attacker can force RSA public-key operations (e.g., verify and encryption) to collapse to deterministic zero outputs and hide “invalid key” errors by supplying a JWK whose modulus decodes to zero.
