Discussion

Cyrus IMAP Server 'index_get_ids()' NULL Pointer Dereference Denial Of Service Vulnerability

Cyrus IMAP Server is prone to a remote denial-of-service vulnerability caused by a NULL-pointer dereference.

Attackers can exploit this issue to cause the server to dereference an invalid memory location, resulting in a denial-of-service condition. Due to the nature of this issue, arbitrary code-execution may be possible; however, this has not been confirmed.

Versions prior to Cyrus IMAP Server 2.4.11 are vulnerable.
