Description: Various vulnerabilities have been reported in NetMail, which can be exploited by malicious people to conduct cross-site scripting attacks or compromise a vulnerable system.
1) Input passed to various calendar display fields in the Modweb agent is not properly sanitised before being returned to users. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
2) An unspecified boundary error when processing a very large name on folder rename through the WebAccess or WebMail client can cause a buffer overflow.
3) Unspecified boundary errors in the handling of long command tags in the IMAP agent can cause heap-based buffer overflows.
4) An integer overflow error in the IMAP command continuation function can cause a heap-based buffer overflow and allows execution of arbitrary code.
