This revision to the recent OpenSSL update, DSA-2896-1, checks for some services that may use OpenSSL in a way that they expose the vulnerability. Such services are proposed to be restarted during the upgrade to help in the actual deployment of the fix. The list of services that are checked is not comprehensive. For a more detailed check, it is recommended to use the checkrestart tool from the debian-goodies package. Note that client applications also need to be restarted. In case of doubt a full system restart is recommended. For reference, the original advisory text follows. A vulnerability has been discovered in OpenSSL"s support for the TLS/DTLS Hearbeat 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 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 is not affected by this vulnerability.
