- Affected Packages:
- Security database references:
- In the Debian bugtracking system: Bug 802671.
In Mitre's CVE dictionary: CVE-2015-7940.
- More information:
The Bouncy Castle Java library before 1.51 does not validate that a point is within 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."
For Debian 6
Squeeze, this issue has been fixed in version 1.44+dfsg-2+deb6u1 of bouncycastle.
Many thanks to upstream author Peter Dettmann who reviewed the backport that we prepared.
