For the stable distribution (wheezy), these problems have been fixed in version 1.0.1e-2+deb7u10. All applications linked to openssl need to be restarted. You can use the tool checkrestart from the package debian-goodies to detect affected programs or reboot your system. There's also a forthcoming security update for the Linux kernel later the day (CVE-2014-3153), so you need to reboot anyway. Perfect timing, isn't it?
For the unstable distribution (sid), these problems will be fixed soon.
We recommend that you upgrade your openssl packages.
Affected Software/OS:
'openssl' package(s) on Debian 7.
Solution:
Please install the updated package(s).
CVSS Score:
6.8
