Problem Description Metamail is a package that implements MIME. Using a configurable "mailcap" file, metamail determines how to treat blocks of electronic mail text based on the content as described by email headers. Some popular packages for handling electronic mail have hooks that allow metamail to be called automatically while a message is being processed. Many buffer overflow conditions exist in version <= 2.7. The lack of boundary checks could lead to execution an arbitrary commands if the receiver processes the messages using the metamail package. The Common Vulnerabilities and Exposures (CVE) project has assigned the name CVE-1999-1263, CVE-1999-0365, and CVE-1999-0037 to this issue. This is a candidate for inclusion in the CVE list (http://cve.mitre.org), which standardizes names for security problems. http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-1999-1263 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-1999-0365 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-1999-0037 2.
