CVE-2019-7524 (opens in a new tab)How to fix?
Upgrade Amazon-Linux:2 dovecot-debuginfo to version 1:2.2.36-6.amzn2 or higher.
This issue was patched in ALAS2-2020-1473.
NVD Description
Note: Versions mentioned in the description apply only to the upstream dovecot-debuginfo package and not the dovecot-debuginfo package as distributed by Amazon-Linux.
See How to fix? for Amazon-Linux:2 relevant fixed versions and status.
In Dovecot before 2.2.36.3 and 2.3.x before 2.3.5.1, a local attacker can cause a buffer overflow in the indexer-worker process, which can be used to elevate to root. This occurs because of missing checks in the fts and pop3-uidl components.
