CVE-2020-28013 (opens in a new tab)Amendment
The Amazon-Linux security team deemed this advisory irrelevant for Amazon-Linux:2018.03.
NVD Description
Note: Versions mentioned in the description apply only to the upstream exim package and not the exim package as distributed by Amazon-Linux.
Exim 4 before 4.94.2 allows Heap-based Buffer Overflow because it mishandles "-F '.('" on the command line, and thus may allow privilege escalation from any user to root. This occurs because of the interpretation of negative sizes in strncpy.
