Debian Security Advisory DSA-3487-1 [email protected]
https://www.debian.org/security/ Salvatore Bonaccorso
February 23, 2016 https://www.debian.org/security/faq
Package : libssh2
CVE ID : CVE-2016-0787
Debian Bug : 815662
Andreas Schneider reported that libssh2, a SSH2 client-side library,
passes the number of bytes to a function that expects number of bits
during the SSHv2 handshake when libssh2 is to get a suitable value for
'group order' in the Diffie-Hellman negotiation. This weakens
significantly the handshake security, potentially allowing an
eavesdropper with enough resources to decrypt or intercept SSH sessions.
For the oldstable distribution (wheezy), this problem has been fixed
in version 1.4.2-1.1+deb7u2.
For the stable distribution (jessie), this problem has been fixed in
version 1.4.3-4.1+deb8u1.
We recommend that you upgrade your libssh2 packages.
