[GLSA-200602-14] noweb: Insecure temporary file creation

Vulnerability Assessment Summary
noweb: Insecure temporary file creation

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200602-14
(noweb: Insecure temporary file creation)

Javier Fernandez-Sanguino has discovered that the lib/toascii.nw
and shell/roff.mm scripts insecurely create temporary files with
predictable filenames.

Impact

A local attacker could create symbolic links in the temporary file
directory, pointing to a valid file somewhere on the filesystem. When
an affected script is called, this would result in the file being
overwritten with the rights of the user running the script.

Workaround

There is no known workaround at this time.
