GNU Emacs version 25.3.1 (and other versions most likely) ignores umask when creating a backup save file ("[ORIGINAL_FILENAME]~") resulting in files that may be world readable or otherwise accessible in ways not intended by the user running the emacs binary.

The remote Redhat Enterprise Linux 5 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - emacs: command injection flaw within enriched mode handling (CVE-2017-14482)

  - vcdiff in Emacs 20.7 to 22.1.50, when used with SCCS, allows local users to overwrite arbitrary files via     a symlink attack on temporary files. (CVE-2008-1694)

  - Emacs 21 and XEmacs automatically load and execute .flc (fast lock) files that are associated with other     files that are edited within Emacs, which allows user-assisted attackers to execute arbitrary code.
    (CVE-2008-2142)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - emacs: command injection flaw within enriched mode handling (CVE-2017-14482)

  - lisp/gnus/gnus-fun.el in GNU Emacs 24.3 and earlier allows local users to overwrite arbitrary files via a     symlink attack on the /tmp/gnus.face.ppm temporary file. (CVE-2014-3421)

  - lisp/emacs-lisp/find-gc.el in GNU Emacs 24.3 and earlier allows local users to overwrite arbitrary files     via a symlink attack on a temporary file under /tmp/esrc/. (CVE-2014-3422)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - emacs: multiple temporary file issues (CVE-2014-3424)

  - emacs: command execution via shell metacharacters (CVE-2022-48337)

  - lisp/gnus/gnus-fun.el in GNU Emacs 24.3 and earlier allows local users to overwrite arbitrary files via a     symlink attack on the /tmp/gnus.face.ppm temporary file. (CVE-2014-3421)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.
