A critical security vulnerability has been discovered and fixed in the popular open-source Exim email server software, which could allow a remote attacker to simply crash or potentially execute malicious code on targeted servers. Exim maintainers today released an urgent security update— Exim version 4.92.3 —after publishing an early warning two days ago, giving system administrators an early head-up on its upcoming security patches that affect all versions of the email server software from 4.92 up to and including then-latest version 4.92.2. Exim is a widely used, open source mail transfer agent (MTA) developed for Unix-like operating systems like Linux, Mac OSX or Solaris, which runs almost 60 percent of the Internet's email servers today for routing, delivering and receiving email messages. This is the second time in this month when the Exim maintainers have released an urgent security update. Earlier this month, the team patched a critical remote code execution flaw (...

A critical remote code execution vulnerability has been discovered in the popular open-source Exim email server software, leaving at least over half a million email servers vulnerable to remote hackers. Exim maintainers today released Exim version 4.92.2 after publishing an early warning two days ago, giving system administrators a heads-up on its upcoming security patches that affect all versions of the email server software up to and including then-latest 4.92.1. Exim is a widely used, open source mail transfer agent (MTA) software developed for Unix-like operating systems such as Linux, Mac OSX or Solaris, which runs almost 60% of the internet's email servers today for routing, delivering and receiving email messages. Tracked as CVE-2019-15846 , the security vulnerability only affects Exim servers that accept TLS connections, potentially allowing attackers to gain root-level access to the system "by sending an SNI ending in a backslash-null sequence during the ini...

Security operations centers (SOCs) are under pressure from both sides: threats are growing more complex and frequent, while security budgets are no longer keeping pace. Today's security leaders are expected to reduce risk and deliver results without relying on larger teams or increased spending. At the same time, SOC inefficiencies are draining resources. Studies show that up to half of all alerts are false positives, with some reports citing false positive rates as high as 99 percent . This means highly trained analysts spend a disproportionate amount of time chasing down harmless activity, wasting effort, increasing fatigue, and raising the chance of missing real threats. In this environment, the business imperative is clear: maximize the impact of every analyst and every dollar by making security operations faster, smarter, and more focused.
