CVE-2019-19920
sa-exim 4.2.1 allows attackers to execute arbitrary code if they can write a .cf file or a rule.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.25%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
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.
