IMAP: Line Buffer Overflow
This protocol anomaly triggers when it detects an IMAP line (from the client to the server) that is too long. This can indicate a buffer overflow attempt. NOTE: Long lines are parsed, which can generate other IMAP overflow errors.
Extended Description
This signature detects malformed IMAP messages having a command line that is too long. Receiving such a message may indicate an attack attempt. The impact of the flaw depends on how a vulnerable IMAP server handles such a malformed message.
