OpenSSH 7.1p1
Posted Aug 25, 2015
Authored by Damien Miller | Site openssh.com

This is a Linux/portable port of OpenBSD's excellent OpenSSH. OpenSSH is based on the last free version of Tatu Ylonen's SSH with all patent-encumbered algorithms removed, all known security bugs fixed, new features reintroduced, and many other clean-ups.

Changes: This is a bugfix release. OpenSSH 7.0 contained a logic error in PermitRootLogin= prohibit-password/without-password that could, depending on compile-time configuration, permit password authentication to root while preventing other forms of authentication. This problem was reported by Mantas Mikulenas.

Western Digital Arkeia Remote Code Execution
Posted Jul 13, 2015
Authored by xistence | Site metasploit.com

This Metasploit module exploits a code execution flaw in Western Digital Arkeia version 11.0.12 and below. The vulnerability exists in the 'arkeiad' daemon listening on TCP port 617. Because there are insufficient checks on the authentication of all clients, this can be bypassed. Using the ARKFS_EXEC_CMD operation it's possible to execute arbitrary commands with root or SYSTEM privileges. The daemon is installed on both the Arkeia server as well on all the backup clients. The module has been successfully tested on Windows, Linux, OSX, FreeBSD and OpenBSD.

Red Hat Security Advisory 2015-0425-02
Posted Mar 5, 2015
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2015-0425-02 - OpenSSH is OpenBSD's SSH protocol implementation. These packages include the core files necessary for both the OpenSSH client and server. It was discovered that OpenSSH clients did not correctly verify DNS SSHFP records. A malicious server could use this flaw to force a connecting client to skip the DNS SSHFP record check and require the user to perform manual host verification of the DNS SSHFP record. It was found that when OpenSSH was used in a Kerberos environment, remote authenticated users were allowed to log in as a different user if they were listed in the ~/.k5users file of that user, potentially bypassing intended authentication restrictions.

It was found that OpenSSH did not properly handle certain AcceptEnv parameter values with wildcard characters. A remote attacker could use this flaw to bypass intended environment variable restrictions.

Red Hat Security Advisory 2013-1591-02

Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2013-1591-02 - OpenSSH is OpenBSD's Secure Shell protocol implementation. These packages include the core files necessary for the OpenSSH client and server. The default OpenSSH configuration made it easy for remote attackers to exhaust unauthorized connection slots and prevent other users from being able to log in to a system. This flaw has been addressed by enabling random early connection drops by setting MaxStartups to 10:30:100 by default. For more information, refer to the sshd_config man page. These updated openssh packages include numerous bug fixes and enhancements. Space precludes documenting all of these changes in this advisory. Users are directed to the Red Hat Enterprise Linux 6.5 Technical Notes, linked to in the References, for information on the most significant of these changes.

Red Hat Security Advisory 2013-0519-02

Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2013-0519-02 - OpenSSH is OpenBSD's Secure Shell protocol implementation. These packages include the core files necessary for the OpenSSH client and server. Due to the way the pam_ssh_agent_auth PAM module was built in Red Hat Enterprise Linux 6, the glibc's error() function was called rather than the intended error() function in pam_ssh_agent_auth to report errors. As these two functions expect different arguments, it was possible for an attacker to cause an application using pam_ssh_agent_auth to crash, disclose portions of its memory or, potentially, execute arbitrary code.

A denial of service flaw was found in the OpenSSH GSSAPI authentication implementation. A remote, authenticated user could use this flaw to make the OpenSSH server daemon use an excessive amount of memory, leading to a denial of service. GSSAPI authentication is enabled by default.

Firewall Builder With GUI 5.1.0.3599
Posted Mar 29, 2012
Site fwbuilder.org

Firewall Builder consists of a GUI and set of policy compilers for various firewall platforms. It helps users maintain a database of objects and allows policy editing using simple drag-and-drop operations. The GUI and policy compilers are completely independent, which provides for a consistent abstract model and the same GUI for different firewall platforms. It currently supports iptables, ipfilter, ipfw, OpenBSD pf, Cisco PIX and FWSM, and Cisco routers access lists.

Changes: Packages for Windows and Mac OS X are now distributed under the GPL, and the source code includes all files necessary to build on Linux, *BSD, Windows, and Mac OS X. This release also includes a few bugfixes in the policy compiler for iptables and for the build problem on Gentoo.
