Description

The aeson library is not safe to use to consume untrusted JSON input. A remote user could abuse this flaw to produce a hash collision in the underlying unordered-containers library by sending specially crafted JSON data, resulting in a denial of service.

• CWE-328Use of Weak HashThe product uses an algorithm that produces a digest (output value) that does not meet security expectations for a hash function that allows an adversary to reasonably determine the original input (preimage attack), find another input that can produce the same hash (2nd preimage attack), or find multiple inputs that evaluate to the same hash (birthday attack).
• CWE-326Inadequate Encryption StrengthThe product stores or transmits sensitive data using an encryption scheme that is theoretically sound, but is not strong enough for the level of protection required.
