Oracle Coherence (Caching, CacheStore and Invocation Components) is prone to a remote vulnerability that allows attackers to take advantage of a Java deserialization vulnerability. By exploiting known methods, it is possible to remotely connect to the Coherence port via T3 protocol to invoke the extract method of the ReflectionExtractor class, which allows the execution of system commands. ExtractorComparator class is used to access ReflectionExtractor class, a bypass for the original patch for CVE-2020-2555.
A remote code execution vulnerability exists when the Windows TCP/IP stack improperly handles ICMPv6 Router Advertisement packets. An attacker who successfully exploited this vulnerability could gain the ability to execute code on the target server or client. To exploit this vulnerability, an attacker would have to send specially crafted ICMPv6 Router Advertisement packets to a remote Windows computer. The update addresses the vulnerability by correcting how the Windows TCP/IP stack handles ICMPv6 Router Advertisement packets.

smtp_mailaddr in smtp_session.c in OpenSMTPD 6.6, as used in OpenBSD 6.6 and other products, allows remote attackers to execute arbitrary commands as root via a crafted SMTP session, as demonstrated by shell metacharacters in a MAIL FROM field. This affects the "uncommented" default configuration. The issue exists because of an incorrect return value upon failure of input validation.
