Synopsis
The remote Debian host is missing a security-related update.
Description
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.
Solution
Upgrade the openssl packages.
For the stable distribution (wheezy), this problem has been fixed in version 1.0.1e-2+deb7u5.
