Millions of Exim mail servers exposed to zero-day RCE attacks.

A critical zero-day vulnerability in all versions of Exim mail transfer agent (MTA) software can let unauthenticated attackers gain remote code execution (RCE) on Internet-exposed servers.

Found by an anonymous security researcher and disclosed through Trend Micro's Zero Day Initiative (ZDI), the security bug (CVE-2023-42115) is due to an Out-of-bounds Write weakness found in the SMTP service.

Apple fixes iOS Kernel zero-day vulnerability on older iPhones

Apple has published security updates for older iPhones and iPads to backport patches released one week ago, addressing two zero-day vulnerabilities exploited in attacks.

"Apple is aware of a report that this issue may have been actively exploited against versions of iOS before iOS 16.6," the company said in an advisory.

The first zero-day (tracked as CVE-2023-42824) is a privilege escalation vulnerability caused by a weakness in the XNU kernel that can let local attackers elevate privileges on vulnerable iPhones and iPads.
