lisp/net/browse-url.el in GNU Emacs 24.3 and earlier allows local users to overwrite arbitrary files via a symlink attack on a /tmp/Mosaic.##### temporary file.

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.

Emacs has been updated to fix the following issues :

  - Several cases of insecure usage of temporary files.
    (CVE-2014-3421 / CVE-2014-3422 / CVE-2014-3423 /     CVE-2014-3424)

  - Use of vc-annotate for renamed files when using Git.

Updated emacs packages fix security vulnerabilities :

Steve Kemp discovered multiple temporary file handling issues in Emacs. A local attacker could use these flaws to perform symbolic link attacks against users running Emacs (CVE-2014-3421, CVE-2014-3422, CVE-2014-3423, CVE-2014-3424).

emacs was updated to fix four security issues.

These security issues were fixed :

  - Avoid unsecure usage of temporary files (CVE-2014-3421).
