Detailed descriptions of the vulnerabilities can be found at: [link moved to references]

It's important that you upgrade the libssl1.0.0 package and not just the openssl package.

All applications linked to openssl need to be restarted. You can use the checkrestart tool from the debian-goodies package to detect affected programs. Alternatively, you may reboot your system.

For the stable distribution (wheezy), these problems have been fixed in version 1.0.1e-2+deb7u12.

For the testing distribution (jessie), these problems will be fixed soon.

For the unstable distribution (sid), these problems have been fixed in version 1.0.1i-1.

We recommend that you upgrade your openssl packages.");
