AV:N/AC:L/Au:N/C:P/I:N/A:N

A vulnerability has been discovered in OpenSSL’s support for the
TLS/DTLS Heartbeat extension. Up to 64KB of memory from either client or
server can be recovered by an attacker. This vulnerability might allow an
attacker to compromise the private key and other sensitive data in
memory.

All users are urged to upgrade their openssl packages (especially
libssl1.0.0) and restart applications as soon as possible.

According to the currently available information, private keys should be
considered as compromised and regenerated as soon as possible. More
details will be communicated at a later time.

The oldstable distribution (squeeze) is not affected by this
vulnerability.

For the stable distribution (wheezy), this problem has been fixed in
version 1.0.1e-2+deb7u5.

For the testing distribution (jessie), this problem has been fixed in
version 1.0.1g-1.

For the unstable distribution (sid), this problem has been fixed in
version 1.0.1g-1.

We recommend that you upgrade your openssl packages.
