Off-by-one error in the SMTP daemon in GroupWise Internet Agent (GWIA) in Novell GroupWise 6.5x, 7.0, 7.01, 7.02, 7.03, 7.03HP1a, and 8.0 allows remote attackers to execute arbitrary code via a long e-mail address in a malformed RCPT command, leading to a buffer overflow.

Multiple buffer overflows in the Internet Agent (aka GWIA) component in Novell GroupWise 7.x before 7.03 HP3 and 8.x before 8.0 HP2 allow remote attackers to execute arbitrary code via (1) a crafted e-mail address in an SMTP session or (2) an SMTP command.

Integer overflow in the WebConsole component in gwia.exe in GroupWise Internet Agent (GWIA) in Novell GroupWise 8.0 before 8.0.3 HP1 and 2012 before SP1 might allow remote attackers to execute arbitrary code via a crafted request that triggers a heap-based buffer overflow, as demonstrated by a request with -1 in the Content-Length HTTP header.
