Summary
cyrus-imapd vulnerabilities
Details
It was discovered that non-authentication-related HTTP requests could be interpreted in an authentication context by a Cyrus IMAP Server when multiple requests arrived over the same connection. An unauthenticated attacker could possibly use this issue to perform a privilege escalation attack. This issue only affected Ubuntu 18.04 LTS. (CVE-2019-18928)
Matthew Horsfall discovered that Cyrus IMAP Server utilized a poor string hashing algorithm that could be abused to control where data was being stored. An attacker could possibly use this issue to perform a denial of service. This issue only affected Ubuntu 18.04 LTS and Ubuntu 20.04 LTS. (CVE-2021-33582)
Damian Poddebniak discovered that Cyrus IMAP Server could interpret specially crafted commands to exploit a memory issue. An authenticated attacker could possibly use this issue to perform a denial of service. This issue only affected Ubuntu 22.04 LTS and Ubuntu 24.04 LTS. (CVE-2024-34055)
