CVE-2015-7940

The Bouncy Castle Java library before 1.51 does not validate a point is withing the elliptic curve, which makes it easier for remote attackers to obtain private keys via a series of crafted elliptic curve Diffie Hellman (ECDH) key exchanges, aka an "invalid curve attack."

Access vector NETWORK

A vulnerability exploitable with network access means the vulnerable software is bound to the network stack and the attacker does not require local network access or local access. Such a vulnerability is often termed "remotely exploitable". An example of a network attack is an RPC buffer overflow.

Access complexity LOW

Specialized access conditions or extenuating circumstances do not exist. The following are examples:

The affected product typically requires access to a wide range of systems and users, possibly anonymous and untrusted (e.g., Internet-facing web or mail server).
The affected configuration is default or ubiquitous.
The attack can be performed manually and requires little skill or additional information gathering.
The race condition is a lazy one (i.e., it is technically a race but easily winnable).

Authentication NONE

Authentication is not required to exploit the vulnerability.

Confidentiality impact PARTIAL

There is considerable informational disclosure. Access to some system files is possible, but the attacker does not have control over what is obtained, or the scope of the loss is constrained. An example is a vulnerability that divulges only certain tables in a database.

Integrity impact NONE

There is no impact to the integrity of the system.

Availability impact NONE

There is no impact to the availability of the system.
