Ubuntu Security Notice 6497-1 - Maxim Levitsky discovered that the KVM nested virtualization implementation for AMD processors in the Linux kernel did not properly handle x2AVIC MSRs. An attacker in a guest VM could use this to cause a denial of service. Alon Zahavi discovered that the NVMe-oF/TCP subsystem in the Linux kernel did not properly handle queue initialization failures in certain situations, leading to a use-after-free vulnerability. A remote attacker could use this to cause a denial of service or possibly execute arbitrary code.

Databases and configuration files can be stored on the server. Databases, logs, and config files can be signed for tamper resistance. In addition to forwarding reports to the log server via authenticated TCP/IP connections, several other logging facilities (e-mail, console, and syslog) are available. Tested on Linux, AIX, HP-UX, Unixware, Sun and Solaris.

6a237f1c777a41ac37dd258a60fea4c6b14f00330ae8d0a6cca7fc1b9bd18c62This Metasploit module exploits a vulnerability in the SmarterTools SmarterMail software for version numbers 16.x and below or for build numbers below 6985. The vulnerable versions and builds expose three .NET remoting endpoints on port 17001, namely /Servers, /Mail and /Spool. For example, a typical installation of SmarterMail Build 6970 will have the /Servers endpoint exposed to the public at tcp://0.0.0.0:17001/Servers, where serialized .NET commands can be sent through a TCP socket connection. The three endpoints perform deserialization of untrusted data (CVE-2019-7214), allowing an attacker to send arbitrary commands to be deserialized and executed. This module exploits this vulnerability to perform .NET deserialization attacks, allowing remote code execution for any unauthenticated user under the context of the SYSTEM account. Successful exploitation results in full administrative control of the target server under the NT AUTHORITY\SYSTEM account. This vulnerability was patched in Build 6985, where the 17001 port is no longer publicly accessible, although it can be accessible locally at 127.0.0.1:17001. Hence, this would still allow for a privilege escalation vector if the server is compromised as a low-privileged user.
c00513d64b0afbcf82cfd8c3569e9b9bd32c506402e79960d11808c409ea5c44Proof of concept exploit for a remotely trigger-able heap buffer overflow vulnerability in iOS 11.4.1 and macOS 10.13.6. This exploit can be used to crash any vulnerable iOS or macOS device that is connected to the same network as the attacker's computer. The vulnerability can be triggered without any user interaction on the victim's device. The exploit involves sending a TCP packet with non-zero options in the IP and TCP headers.
