Security Vulnerabilities - CVEs Published In December 2017
An issue was discovered in the software on Vaultek Gun Safe VT20i products, aka BlueSteal. An attacker can remotely unlock any safe in this product line without a valid PIN code. Even though the phone application requires it and there is a field to supply the PIN code in an authorization request, the safe does not check the PIN code, so an attacker can obtain authorization using any value. Once an attacker sees the Bluetooth Low Energy (BLE) advertisement for the safe, they need only to write a BLE characteristic to enable notifications, and send a crafted getAuthor packet that returns a temporary key, and an unlock packet including that temporary key. The safe then opens after the unlock packet is processed, with no verification of PIN or other credentials.

An issue was discovered in the software on Vaultek Gun Safe VT20i products. There is no encryption of the session between the Android application and the safe. The website and marketing materials advertise that this communication channel is encrypted with "Highest Level Bluetooth Encryption" and "Data transmissions are secure via AES256 bit encryption." These claims, however, are not true. Moreover, AES256 bit encryption is not supported in the Bluetooth Low Energy (BLE) standard, so it would have to be at the application level. This lack of encryption allows an individual to learn the passcode by eavesdropping on the communications between the application and the safe.

net/netfilter/nfnetlink_cthelper.c in the Linux kernel through 4.14.4 does not require the CAP_NET_ADMIN capability for new, get, and del operations, which allows local users to bypass intended access restrictions because the nfnl_cthelper_list data structure is shared across all net namespaces.

The __netlink_deliver_tap_skb function in net/netlink/af_netlink.c in the Linux kernel through 4.14.4, when CONFIG_NLMON is enabled, does not restrict observations of Netlink messages to a single net namespace, which allows local users to obtain sensitive information by leveraging the CAP_NET_ADMIN capability to sniff an nlmon interface for all Netlink activity on the system.

net/netfilter/xt_osf.c in the Linux kernel through 4.14.4 does not require the CAP_NET_ADMIN capability for add_callback and remove_callback operations, which allows local users to bypass intended access restrictions because the xt_osf_fingers data structure is shared across all net namespaces.

A cross-origin vulnerability has been discovered in the Auth0 auth0.js library affecting versions < 8.12. This vulnerability allows an attacker to acquire authenticated users' tokens and invoke services on a user's behalf if the target site or application uses a popup callback page with auth0.popup.callback().

The Mem_File_Reader::read_avail function in Data_Reader.cpp in the Game_Music_Emu library (aka game-music-emu) 0.6.1 does not ensure a non-negative size, which allows remote attackers to cause a denial of service (application crash) via a crafted file.
