13 Mar 2014

Affected Packages:

libssh

Vulnerable:

Yes

Security database references:

In Mitre's CVE dictionary: CVE-2014-0017.

More information:

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.

We recommend that you upgrade your libssh packages.
