In addition this update disables the insecure Dual_EC_DRBG algorithm (which was unused anyway, see [link moved to references] for further information) and no longer uses the RdRand feature available on some Intel CPUs as a sole source of entropy unless explicitly requested.
For the stable distribution (wheezy), these problems have been fixed in version 1.0.1e-2+deb7u1.
For the unstable distribution (sid), these problems have been fixed in version 1.0.1e-5.
