Descriptions

In Emacs before 29.3, Gnus treats inline MIME contents as trusted.

En Emacs anterior a 29.3, Gnus trata el contenido MIME en línea como confiable.

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.

Multiple vulnerabilities have been discovered in GNU Emacs and Org Mode, the worst of which could lead to arbitrary code execution. Versions greater than or equal to 26.3-r16:26 are affected.
