  "description": "MIME::Parser::FileUnder versions before 5.521 for Perl reuse a pre-created output directory and follow symlinks in it, letting local users redirect attachment writes.  Each message is written to a directory named msg-\u003Ctime\u003E-\u003Cpid\u003E-\u003Cn\u003E under the output base, and an existing directory of that name is used as is. A file name counts as unused when nothing exists at that path, which holds for a dangling symlink, and the body file is then opened in a way that follows the link.  When the output base is writable by other users, as with output_under(\u0022/tmp\u0022), a local user can pre-create the directory with a symlink named like an attachment. The parser then writes the attachment to the link target with the privileges of the parsing process.",
