  "title": "libjwt3: LibJWT is a C JSON Web Token Library",
  "description": "LibJWT is a C JSON Web Token Library. Starting in version 3.0.0 and prior to version 3.3.0, the JWK parsing for RSA-PSS did not protect against a NULL value when expecting to parse JSON string values. A specially crafted JWK file could exploit this behavior by using integers in places where the code expected a string. This was fixed in v3.3.0. A workaround is available. Users importing keys through a JWK file should not do so from untrusted sources. Use the \u0060jwk2key\u0060 tool to check for validity of a JWK file. Likewise, if possible, do not use JWK files with RSA-PSS keys.",
