Dist Slackware Esm H88
Recent libssh updates for Slackware resolve a critical key generation vulnerability. It's essential to update promptly to maintain system security and protect integrity.
New libssh packages are available for Slackware 14.0, 14.1, and -current to fix a security issue

Summary

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: https://www.cve.org/CVERecord?id=CVE-2016-0739 (* Security fix *)
