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 Internet Messaging System (NIMS) 2.6 and 3.0, and NetMail 3.1 and 3.5, is installed with a default NMAP authentication credential, which allows remote attackers to read and write mail store data if the administrator does not change the credential by using the NMAP Credential Generator.
