Multiple buffer overflows in Novell NetMail before 3.52e FTF2 allow remote attackers to execute arbitrary code (1) by appending literals to certain IMAP verbs when specifying command continuation requests to IMAPD, resulting in a heap overflow; and (2) via crafted arguments to the STOR command to the Network Messaging Application Protocol (NMAP) daemon, resulting in a stack overflow.

Stack-based buffer overflow in the IMAP daemon (IMAPD) in Novell NetMail before 3.52e FTF2 allows remote authenticated users to execute arbitrary code via unspecified vectors involving the APPEND command.

Novell NetMail automatically processes HTML in an attachment without prompting the user to save or open it, which makes it easier for remote attackers to conduct web-based attacks and steal cookies.
