NVD Description
Note: Versions mentioned in the description apply only to the upstream procmail package and not the procmail package as distributed by RHEL.
See How to fix? for RHEL:7 relevant fixed versions and status.
Heap-based buffer overflow in the loadbuf function in formisc.c in formail in procmail 3.22 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted e-mail message because of a hardcoded realloc size, a different vulnerability than CVE-2014-3618.
