Description
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.
Affected configurations
• sa-exim project sa-exim 4.2.1
• canonical ubuntu linux 16.04
• debian debian linux 8.0
• debian debian linux 9.0
• debian debian linux 10.0
