The PGP signature parsing in Module::Signature before 0.74 allows remote attackers to cause the unsigned portion of a SIGNATURE file to be treated as the signed portion via unspecified vectors.
The product does not verify, or incorrectly verifies, the cryptographic signature for data.
https://cwe.mitre.org/data/definitions/347.html →Open in CWE collection →When converting from one data type to another, such as long to integer, data can be omitted or translated in a way that produces unexpected values. If the resulting values are used in a sensitive context, then dangerous behaviors may occur.
https://cwe.mitre.org/data/definitions/681.html →Open in CWE collection →An adversary is able to efficiently decrypt data without knowing the decryption key if a target system leaks data on whether or not a padding error happened while decrypting the ciphertext. A target system that leaks this type of information becomes the padding oracle and an adversary is able to make use of that oracle to efficiently decrypt data without knowing the decryption key by issuing on average 128*b calls to the padding oracle (where b is the number of bytes in the ciphertext block). In addition to performing decryption, an adversary is also able to produce valid ciphertexts (i.e., perform encryption) by using the padding oracle, all without knowing the encryption key.
