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.

Buffer overflow in the Modweb agent for Novell NetMail 3.52 before 3.52C, when renaming folders, may allow attackers to execute arbitrary code.

Buffer overflow in the IMAP command continuation function in Novell NetMail 3.52 before 3.52C may allow remote attackers to execute arbitrary code.

Multiple buffer overflows in Novell NetMail (NIMS) 3.0.3 before 3.0.3C allows remote attackers to cause a denial of service and possibly execute arbitrary code via (1) WebAdmin or (2) ModWeb.

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.

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.

Buffer overflows in IMAP Agent (imapd) for Novell NetMail (NIMS) 3.0.3 before 3.0.3A allows remote attackers to cause a denial of service.

Cross-site scripting (XSS) vulnerability in the ModWeb agent for Novell NetMail 3.52 before 3.52C allows remote attackers to inject arbitrary web script or HTML via calendar display fields.
