Detail
| It was discovered that libssh, a tiny C SSH library, did not reset the state of the PRNG after accepting a connection. A server mode application that forks itself to handle incoming connections could see its children sharing the same PRNG state, resulting in a cryptographic weakness and possibly the recovery of the private key. For the oldstable distribution (squeeze), this problem has been fixed in version 0.4.5-3+squeeze2. For the stable distribution (wheezy), this problem has been fixed in version 0.5.4-1+deb7u1. For the testing distribution (jessie), this problem has been fixed in version 0.5.4-3. For the unstable distribution (sid), this problem has been fixed in version 0.5.4-3. We recommend that you upgrade your libssh packages. |
