Debian Security Advisory DSA-3488-1 security@debian.org
https://www.debian.org/security/ Salvatore Bonaccorso
February 23, 2016 https://www.debian.org/security/faq
- -------------------------------------------------------------------------
Package : libssh
CVE ID : CVE-2016-0739
Debian Bug : 815663
Aris Adamantiadis discovered that libssh, a tiny C SSH library,
incorrectly generated a short ephemeral secret for the
diffie-hellman-group1 and diffie-hellman-group14 key exchange methods.
The resulting secret is 128 bits long, instead of the recommended sizes
of 1024 and 2048 bits respectively. This flaw could allow an
eavesdropper with enough resources to decrypt or intercept SSH sessions.
For the oldstable distribution (wheezy), this problem has been fixed in
version 0.5.4-1+deb7u3. This update also includes fixes for
CVE-2014-8132 and CVE-2015-3146, which were previously scheduled for the
next wheezy point release.
For the stable distribution (jessie), this problem has been fixed in
version 0.6.3-4+deb8u2.
We recommend that you upgrade your libssh packages.
