- 漏洞讨论

A vulnerability has been reported for mpack/munpack 1.5. Reportedly, it is possible to cause munpack to create files outside of a designated directory. When mpack/munpack receives a MIME encoded message with an attachment that refers to a file, using a '../' sequence followed by the filename, it may decode the attachment outside of a designated directory.
