is there any 100% working method to update openssl to the non vulnerable version on Debian Wheezy. I do not want to upgrade the whole OS, nor would I like to install a non official package.
Is there any solution right now ?
For the stable distribution (wheezy), this problem has been fixed in version 1.0.1e-2+deb7u5.
so, assuming you have:
deb http://security.debian.org/ wheezy/updates main contrib non-free
in your /etc/apt/sources.list file
apt-get update apt-cache policy openssl apt-get install openssl
apt-cache policy openssl will show you candidate updates
apt-get install openssl will upgrade to last openssl version
apt-cache policy openssl and check version at Installed: line is equal or superior to: 1.0.1e-2+deb7u5
upgrading openssl package should upgrade libssl1.0.0 as it's a dependency
