Doc Text:
A flaw was found in Emacs. When Emacs is used as an email client, inline MIME attachments are considered to be trusted by default, allowing a crafted LaTeX document to exhaust the disk space or the inodes allocated for the partition where the /tmp directory is located. This issue possibly results in a denial of service.
