  script_tag(name:"insight", value:"It was discovered that the Cyrus IMAP server was prone to a denial of service attack via input that is mishandled during hash-table interaction. Furthermore it allowed privilege escalation because an HTTP request may be interpreted in the authentication context of an unrelated previous request that arrived over the same connection.

For Debian 9 stretch, these problems have been fixed in version 2.5.10-3+deb9u3.

We recommend that you upgrade your cyrus-imapd packages.

For the detailed security status of cyrus-imapd please refer to its security tracker page at: [link moved to references]

Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: [link moved to references]");
