GHSA-PRXX-4M38-9M83

Vulnerability from github – Published: 2022-05-24 19:12 – Updated: 2022-05-24 19:12

Details

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.

Severity ?

7.5 (High)
