Cisco Security Advisory – A vulnerability in Cisco NX-OS Software running on Cisco Nexus 3000 Series Switches and Cisco Nexus 3500 Platform Switches could allow an unauthenticated, remote attacker to log in to the device with the privileges of the root user with bash shell access. The vulnerability is due to a user account that has a default and static password. This account is created at installation and cannot be changed or deleted without impacting the functionality of the system. An attacker could exploit this vulnerability by connecting to the affected system using this default account. The account can be used to authenticate remotely to the device via Telnet (or SSH on a specific release) and locally on the serial console. Cisco has released software updates that address this vulnerability. Workarounds that address this vulnerability are available.

Cisco Security Advisory – A vulnerability in the TCP stack of Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition. The vulnerability is due to improper processing of certain TCP packets in the closing sequence of a TCP session while the affected device is in a TIME_WAIT state. An attacker could exploit this vulnerability by sending a specific TCP packet to an affected device on a TCP session that is already in a TIME_WAIT state. An exploit could allow the attacker to cause a reload of the TCP stack on the affected device, resulting in a DoS condition. This vulnerability can be exploited using either IPv4 or IPv6 packets. The vulnerability can be triggered by a crafted sequence of TCP packets destined for TCP ports listening on the device. The packets may use the IPv4 or IPv6 unicast address of any interface configured on the device. This vulnerability can be triggered only by traffic destined to an affected device and cannot be exploited using traffic that transits an affected device. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

Red Hat Security Advisory 2016-0346-01 – PostgreSQL is an advanced object-relational database management system. An integer overflow flaw, leading to a heap-based buffer overflow, was found in the PostgreSQL handling code for regular expressions. A remote attacker could use a specially crafted regular expression to cause PostgreSQL to crash or possibly execute arbitrary code.
