Package : bouncycastle
Version : 1.44+dfsg-2+deb6u1
CVE ID : CVE-2015-7940
Debian Bug : 802671

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.
