[slackware-security] libssh (SSA:2016-057-01)

New libssh packages are available for Slackware 14.0, 14.1, and -current to
fix a security issue.


Here are the details from the Slackware 14.1 ChangeLog:
+--------------------------+
patches/packages/libssh-0.7.3-i486-1_slack14.1.txz: Upgraded.
Fixed weak key generation. Due to a bug in the ephemeral secret key
generation for the diffie-hellman-group1 and diffie-hellman-group14
methods, ephemeral secret keys of size 128 bits are generated, instead
of the recommended sizes of 1024 and 2048 bits, giving a practical
security of 63 bits.
For more information, see:
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2016-0739
(* Security fix *)
