Wireshark ‘dissectors/asn1/ros/packet-ros-template.c’ Denial of Service Vulnerability
Description: In Wireshark 2.2.0 to 2.2.6, the ROS dissector could crash with a NULL pointer dereference. This was addressed in epan/dissectors/asn1/ros/packet-ros-template.c by validating an OID. Impact: Attackers can exploit this issue to crash the affected application, resulting in denial-of-service conditions. Mitigation: Upgrade to Wireshark 2.2.7 or later.

FreeRADIUS TLS CVE-2017-9148 Authentication Bypass Vulnerability
Description: The TLS session cache in FreeRADIUS before 3.0.14 fails to reliably prevent resumption of an unauthenticated session, which allows remote attackers (such as malicious 802.1X supplicants) to bypass authentication via PEAP or TTLS. Impact: An attacker can exploit this issue to bypass the authentication mechanism and perform unauthorized actions. This may lead to further attacks. FreeRADIUS versions prior to 3.0.14 are vulnerable. Mitigation: Updates...
