Description

Mail Notification contains a flaw that may allow a remote denial of service. The issue is triggered when an out of context continuation response sent by a malicious IMAP server causes a null pointer dereference to occur in the IMAP code strcmp() function, and results in loss of availability for the service. Note: To exploit this vulnerability the attacker must first hijack the connection between Mail Notification and the IMAP server.
