Vulnerability from fkie_nvd - Published: 2019-12-22 18:15 - Updated: 2026-06-17 02:27
Severity
Summary
sa-exim 4.2.1 allows attackers to execute arbitrary code if they can write a .cf file or a rule. This occurs because Greylisting.pm relies on eval (rather than direct parsing and/or use of the taint feature). This issue is similar to CVE-2018-11805.
