CVE-2021-33582 (GCVE-0-2021-33582)

Vulnerability from cvelistv5 – Published: 2021-09-01 05:32 – Updated: 2024-08-03 23:50
VLAI
Summary
Cyrus IMAP before 3.4.2 allows remote attackers to cause a denial of service (multiple-minute daemon hang) via input that is mishandled during hash-table interaction. Because there are many insertions into a single bucket, strcmp becomes slow. This is fixed in 3.4.2, 3.2.8, and 3.0.16.
