CVE-2017-12972

CVE-2017-12972 : Nimbus JOSE+JWT before 4.39 has no integer-overflow check when converting length values from bytes to bits, enabling a remote attacker to perform a HMAC bypass by shifting AAD and ciphertext so different plaintext yields the same HMAC. Public records show this vulnerability discu...

CVE-2017-12972

In Nimbus JOSE+JWT before 4.39, there is no integer-overflow check when converting length values from bytes to bits, which allows attackers to conduct HMAC bypass attacks by shifting Additional Authenticated Data AAD and ciphertext so that different plaintext is obtained for the same HMAC...

CVE-2017-12973

Nimbus JOSE+JWT prior to 4.39 proceeds after detecting an invalid HMAC in authenticated AES-CBC decryption, enabling a padding oracle attack. Affected: Nimbus JOSE+JWT library (Connect2id). Risk: padding oracle could leak data or enable exploitation. Remediation: upgrade to version 4.39 or later ...

Timing Attacks

Malcolm Fell jwt is vulnerable to timing attacks. The library does not compare hashes in constant time, which allows malicious users to use the timing of the request to progressively identify a valid hash...

CVE-2017-8034

The Cloud Controller and Router in Cloud Foundry CAPI-release capi versions prior to v1.32.0, Routing-release versions prior to v0.159.0, CF-release versions prior to v267 do not validate the issuer on JSON Web Tokens JWTs from UAA. With certain multi-zone UAA configurations, zone administrators...

Code injection

A bug in the standard library ScalarMult implementation of curve P-256 for amd64 architectures in Go before 1.7.6 and 1.8.x before 1.8.2 causes incorrect results to be generated for specific input points. An adaptive attack can be mounted to progressively extract the scalar input to ScalarMult by...
