CVE-2017-7650

In Mosquitto before 1.4.12, pattern based ACLs can be bypassed by clients that set their username/client id to '' or '+'. This allows locally or remotely connected clients to access MQTT topics that they do have the rights to. The same issue may be present in third party authentication/access...

The vulnerability of the ACL component of the NoviWare operating system allows a attacker to gain access to the network interface of the novi_process_manager_daemon service and execute arbitrary code in privileged mode on the switch.

The vulnerability of NoviWare’s operating system component stems from the improper handling of unserialized network packets, which leads to buffer overflows on the stack. Exploiting this vulnerability allows a malicious actor to execute arbitrary code during the application of ACL modifications,...

The vulnerability of NoviWare’s operating system component, caused by a buffer overflow in the stack, allows an attacker to execute arbitrary code.

The vulnerability of NoviWare’s operating system component lies in the overflow of memory in the stack. Exploiting this vulnerability allows a malicious actor to execute arbitrary code during the application of ACL changes, using specially crafted network packets containing operating system...

CVE-2017-12213

The CVE-2017-12213 issue affects Cisco Catalyst 4000 Series Switches running IOS XE. It stems from an uncaught error when reassigning the auth-default-ACL dynamic ACL after 802.1x authentication fails, allowing an unauthenticated adjacent attacker to cause the dynamic ACL to fail open and forward...

kernel: Setting a POSIX ACL via setxattr doesn't clear the setgid bit

It was found that when file permissions were modified via chmod and the user modifying them was not in the owning group or capable of CAPFSETID, the setgid bit would be cleared. Setting a POSIX ACL via setxattr sets the file permissions as well as the new ACL, but doesn't clear the setgid bit in ...
