Vulnerability Title
Go JOSE affect by a panic in JWE decryption
Vulnerability Description
Go JOSE provides an implementation of the Javascript Object Signing and Encryption set of standards in Go, including support for JSON Web Encryption (JWE), JSON Web Signature (JWS), and JSON Web Token (JWT) standards. Prior to 4.1.4 and 3.0.5, decrypting a JSON Web Encryption (JWE) object will panic if the alg field indicates a key wrapping algorithm (one ending in KW, with the exception of A128GCMKW, A192GCMKW, and A256GCMKW) and the encrypted_key field is empty. The panic happens when cipher.KeyUnwrap() in key_wrap.go attempts to allocate a slice with a zero or negative length based on the length of the encrypted_key. This code path is reachable from ParseEncrypted() / ParseEncryptedJSON() / ParseEncryptedCompact() followed by Decrypt() on the resulting object. Note that the parse functions take a list of accepted key algorithms. If the accepted key algorithms do not include any key wrapping algorithms, parsing will fail and the application will be unaffected. This panic is also reachable by calling cipher.KeyUnwrap() directly with any ciphertext parameter less than 16 bytes long, but calling this function directly is less common. Panics can lead to denial of service. This vulnerability is fixed in 4.1.4 and 3.0.5.

Vulnerability Title
Go JOSE 安全漏洞
Vulnerability Description
Go JOSE是Go JOSE开源的一个 Go 中 JOSE 标准的实现。 Go JOSE 4.1.4之前版本和3.0.5之前版本存在安全漏洞，该漏洞源于解密JSON Web Encryption对象时，如果alg字段指示密钥包装算法且encrypted_key字段为空，可能导致程序崩溃和拒绝服务。
