Title:	Slackware: Security Advisory (SSA:2016-014-01)
Summary:	The remote host is missing an update for the 'openssh' package(s) announced via the SSA:2016-014-01 advisory.
Description:	Summary: The remote host is missing an update for the 'openssh' package(s) announced via the SSA:2016-014-01 advisory. Vulnerability Insight: New openssh packages are available for Slackware 13.0, 13.1, 13.37, 14.0, 14.1, and -current to fix security issues. Here are the details from the Slackware 14.1 ChangeLog: +--------------------------+ patches/packages/openssh-7.1p2-i486-1_slack14.1.txz: Upgraded. This update fixes an information leak and a buffer overflow. In particular, the information leak allows a malicious SSH server to steal the client's private keys. Thanks to Qualys for reporting this issue. For more information, see: [links moved to references] ***************************************************************** * IMPORTANT: READ BELOW ABOUT POTENTIALLY INCOMPATIBLE CHANGES * ***************************************************************** Rather than backport the fix for the information leak (which is the only hazardous flaw), we have upgraded to the latest OpenSSH. As of version 7.0, OpenSSH has deprecated some older (and presumably less secure) algorithms, and also (by default) only allows root login by public-key, hostbased and GSSAPI authentication. Make sure that your keys and authentication method will allow you to continue accessing your system after the upgrade. The release notes for OpenSSH 7.0 list the following incompatible changes to be aware of: * Support for the legacy SSH version 1 protocol is disabled by default at compile time. * Support for the 1024-bit diffie-hellman-group1-sha1 key exchange is disabled by default at run-time. It may be re-enabled using the instructions at [link moved to references] * Support for ssh-dss, ssh-dss-cert-* host and user keys is disabled by default at run-time. These may be re-enabled using the instructions at [link moved to references] * Support for the legacy v00 cert format has been removed. * The default for the sshd_config(5) PermitRootLogin option has changed from 'yes' to 'prohibit-password'. * PermitRootLogin=without-password/prohibit-password now bans all interactive authentication methods, allowing only public-key, hostbased and GSSAPI authentication (previously it permitted keyboard-interactive and password-less authentication if those were enabled). (* Security fix *) +--------------------------+ Affected Software/OS: 'openssh' package(s) on Slackware 13.0, Slackware 13.1, Slackware 13.37, Slackware 14.0, Slackware 14.1, Slackware current. Solution: Please install the updated package(s). CVSS Score: 4.6 CVSS Vector: AV:N/AC:H/Au:S/C:P/I:P/A:P
