Dan Rosenberg discovered that fastjar incorrectly handled file paths containing ‘…’ when unpacking archives. If a user or an automated system were tricked into unpacking a specially crafted jar file, arbitrary files could be overwritten with user privileges.
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
