emacsclient-mail.desktop in Emacs 28.1 through 28.2 is vulnerable to Emacs Lisp code injections through a crafted mailto: URI with unescaped double-quote characters. It is fixed in 29.0.90.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - emacsclient-mail.desktop in Emacs 28.1 through 28.2 is vulnerable to Emacs Lisp code injections through a     crafted mailto: URI with unescaped double-quote characters. It is fixed in 29.0.90. (CVE-2023-27986)

Note that Nessus relies on the presence of the package as reported by the vendor.

An update of the emacs package has been released.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - emacsclient-mail.desktop in Emacs 28.1 through 28.2 is vulnerable to Emacs Lisp code injections through a
    crafted mailto: URI with unescaped double-quote characters. It is fixed in 29.0.90. (CVE-2023-27986)

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - GNU Emacs through 28.2 allows attackers to execute commands via shell metacharacters in the name of a
    source-code file, because lib-src/etags.c uses the system C library function in its implementation of the
    ctags program. For example, a victim may use the "ctags *" command (suggested in the ctags documentation)
    in a situation where the current working directory has contents that depend on untrusted input.
    (CVE-2022-45939)

  - emacsclient-mail.desktop in Emacs 28.1 through 28.2 is vulnerable to Emacs Lisp code injections through a
    crafted mailto: URI with unescaped double-quote characters. It is fixed in 29.0.90. (CVE-2023-27986)

The version of emacs installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2023-27986 advisory.

  - emacsclient-mail.desktop in Emacs 28.1 through 28.2 is vulnerable to Emacs Lisp code injections through a     crafted mailto: URI with unescaped double-quote characters. It is fixed in 29.0.90. (CVE-2023-27986)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-134 advisory.

    emacsclient-mail.desktop in Emacs 28.1 through 28.2 is vulnerable to shell command injections through a     crafted mailto: URI. This is related to lack of compliance with the Desktop Entry Specification.
    (CVE-2023-27985)

    emacsclient-mail.desktop in Emacs 28.1 through 28.2 is vulnerable to Emacs Lisp code injections through a     crafted mailto: URI with unescaped double-quote characters. (CVE-2023-27986)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
